Abstract Recent progresses have been advanced in many topics of interests to rock mechanics, geosciences, and multi-disciplinary interactions. These progresses are associated with deepening of shafts and lengthening of tunnels in many underground research laboratories (URLs) and facilities, designing and initiations of different heater and radioactive tracer experiments, enlarging existing or excavating of new experimental halls, and monitoring and measuring of disturbed/damaged zones and rock burst processes under stresses in underground tunnels. In this review and summary, we describe what an International Society for Rock Mechanics (ISRM) URL Networking Commission has learned since its formation in 2011. Various workshops, meetings, presentations, and literature reviews contribute to our better understanding and exchanges associated with this URL and other ISRM Commissions. We realize that there are interests and progresses not only in the URL Networking but also in many excavation studies associated with underground power plants (both hydropower and nuclear types), in many field experiments for understanding coupled thermal-hydro-chemical-biological processes, and in increasing activities associated with field demonstrations and assessments of energy recovery and waste sequestration studies. The summary in this presentation will tailor to supplement many related presentations planned in the 8th Asian Rock Mechanics Symposium.

ABSTRACT: Waste-less mining is becoming a key issue in industrialized nations such as Japan and European countries where mining activities are shrinking and environmental sensitivities are increasing. The Kamioka mine, a leading metal mine located in the mountainous region of Japan, has launched a couple of underground space businesses and battery scrap recycling. The Kamioka mine has initiated experimental programs of CAES (Compressed Air Energy Storage) and decompressed air chamber as well as underground test sites for explosives. These testing projects having yielded some successful results, however, the most epoch-making one must be the Super-KAMIOKANDE (KAMIOKA Nucleon Decay Experiment) project. It is a scientific program to detect astronomical neutrinos in a subsurface observatory excavated at a depth of about l000m below the surface for insulation. We have discussed and reviewed the qualified and informed underground technologies having been applied for the Super-KAMIOKANDE project. RÉSUMÉ: L'exploitation minière sans gaspillage est devenue recemment dans les pays industrialises comme Ie Japon ou les pays europeens où l'importance des activites minières diminue continuellement et où les considerations environnementales s'intensifient une question de première importance. La mine de Kamioka, l'une des plus grandes mines du Japon situee dans la region montagneuse, a lance plusieurs projets concernant l'exploitation de l'espace souterrain ainsi que Ie recyclage de batteries usagees. On a entrepris dans la mine de Kamioka divers projets experimentaux en rapport avec Ie stockage d'energie produite par l'air cornprirne (CAES/Compressed Air Energy Storage), de chambre il air decornpresse ainsi que des sites experimentaux d'essais pour les matieres explosives. Ces programmes d'essais ont produit des resultats couronnes de succes et prometteurs. Toutefois, Ie projet faisant vraiment date doit etre probablement le projet Super-KAMIOKANDE (denomination abregee pour Ie Projet experimental de decomposition des Nucleons de Kamioka). II s'agit d'un programme scientifique visant il detecter les neutrinos venus de l'espace dans un observatoire souterrain creuse sous la surface du sot il une profondeur approximative de 1.000 metres afin d'etre isole de l'exterieur, Nous avons examine et fait la synthese dans cette etude des techniques souterraines de pointe et hautement informatisees appliquees lors de la construction du Super-KAMIOKANDE dans la mine de Kamioka. ZUSAMMENFASSUNG: Verlustloser Bergbau wird in den industrialisierten Nationen wie Japan oder europaischen Lander in denen der Bergbau allmahlich abnimmt wahrend die Umweltbewuβtheit immer wieder störker werden, zunehmend bedeutend. Kamioka, eine der leitende Erzgrube im japanischen Gebirge, setzte ein paar Untertage-raumgeschaft und die Aufbereitung der Altbatterien in Gang. Bergwerk Kamioka leitete auch einige Versuchsprogramme einschlieβlich CAES (Druckluft-energieaufbewahrung), druckentlasteter Kammer so wie Untertage-pruefungsraum fuer Sprengstoffe. Diese Versuchsprojekte brach einige erfolgreichen Ergebnisse jedoch das auβerst epochemachende Projekt war das Super-KAMIOKANDE (Kamioka Nukleonzerfallexperiment) Projekt. Das ist ein wissenschaftliche Programm um astronomische Neutrinos, in eine unterirdische Beobachtungskammer die absichtlich fuer Isolierung l000m unter der Erdoberflache ausgeraumt wurde, zu entdecken. Die hochentwickelte und informatorische untertagige Ausbruchtechniken die durch lange Erfahrung des Untertageausbaus in Bergwerk Kamioka entwickelt wurde und auf den Ausbau der super-KAMIOKANDE angewandt wurde, werden erörtert und zusammengefaβt. 1 INTRODUCTION The Kamioka mine is located in Gifu Prefecture and at an elevation of 400 m in the heart of the high and massive mountain range called the Japanese Alps, approximately 60km inland from the Sea of Japan (Fig. 1). The mine has a long history and dates. back to around 720 AD, initially having opened as a gold, silver, and copper mine. However, the production of zinc and lead ore became dominant, and at last modernized lead and zinc smelters were constructed during the second half of 1800s. In the fiscal year of 1997, the mine excavated 2278 t/day of Zn-Pb crude ores with the average grades of 3.70% Zn, 0.26% Pb, and 17g/t Ag, from which 35,253 t/year of zinc concentrates and 1945 t/year of lead concentrates were processed as well.

ABSTRACT This paper provides an overview of the status of the design and construction planning for a new generation of deep Underground Research Laboratories (URL’s). These facilities are under preliminary design for candidate sites in Asia, Europe and North America. As currently scoped, all the proposed underground facilities would be large. To provide the platform necessary to support a major research thrust the life cycle facility costs will represent a significant long-term budgetary commitment on the part of the sponsoring agencies. To improve the viability of these laboratory ventures the paper stresses the need for adroit collaboration between research stakeholders, designer and builders throughout the siting, design and construction process. A process that properly integrates a consideration of ground conditions and site constraints in the development of final design solutions will best guarantee the delivery of a set of fit-for-purpose and cost-effective underground facilities 1. INTRODUCTION The demand for research space at depth has grown rapidly in recent years. The scientific goals that drive the desire to perform deep research are compelling, but space is limited. Most Underground Research Laboratories (URL’s) built to date are sited at shallow depth, and the research conducted within them highly targeted to study key issues related to specific end-uses, most notably those associated with the long-term storage of nuclear waste. The few deeper URL’s that have been built are generally compact, hosting physics experiments devised to investigate important astrophysics phenomena and the study of elemental particles. These facilities have typically been built adjacent to operating mine and transportation tunnels where researchers can share access and services with a parent operator. The handful of deep URL’s in operation today cannot accommodate the growing demand for space at depth identified by underground researchers, including physicists, biologists, geologists, earth scientist and rock engineers. In the last decade the need to develop more deep space for research has been recognized by the international community. A number of studies have been launched to evaluate the feasibility and cost of expanding existing sites or constructing new laboratories at locations in Asia, Europe, and North America. A wide range of underground openings are planned for construction within the scope of these new studies. Opening inventories include long exploratory galleries and large volume, wide span caverns. Kilometers of small cross-section galleries are needed to explore conditions within the host rock mass and gain access to laboratory sites. Large caverns, with mined volumes in excess of half a million cubic meters and spans of up to 70m, are required to contain major new physics experiments. The engineering specification of some of these laboratory spaces may also include provisions for the safe storage of large quantities of toxic and cryogenic fluids. The design challenges associated with delivering cost-effective solutions for URL’s are discussed in the paper by reference to the decades of experience gained in the developing and operating of existing laboratory facilities. The paper will also describe some of the new URL sites that are currently under consideration for the siting of major new experiments.

ABSTRACT Construction of a Deep Underground Science and Engineering Laboratory (DUSEL) has been proposed under the auspices of the US National Science Foundation.The DUSEL facility will provide a diverse group of scientists and engineers with a dedicated underground facility capable of supporting a broad spectrum of fundamental and applied research at depth in the Earth's crust. In 2005, NSF selected two sites for funded conceptual study. The two sites are at the Henderson Mine in Colorado and the Homestake Mine in South Dakota. Both sites take advantage of existing mined facilities to provide access and infrastructure support to the DUSEL. This paper discusses key aspects of an integrated design and research program being developed to support the construction of a large-deep cavern to house a new generation of physics detector. The detector proposals are being developed to pursue research into the properties and behaviors of fundamental particles, the neutrino and the proton. As currently scoped, these proposals call for the excavation of large-span caverns, over 50m wide, mined at depths in excess of a kilometer. The paper discusses the main engineering features of the project and emphasizes the need to select the most appropriate state-of-the-art technologies in site investigation, excavation, ground treatment and reinforcement in order to deliver a safe, cost-effective, and fit-for-purpose opening. The DUSEL will also include opportunities for earth scientists and engineers to study key aspects of rock mass behavior at depth, notably under conditions of high stress, a key challenge faced by today's underground engineering community. The paper proposes that adroit coordination between earth scientists and the engineers responsible for cavern design and construction can be mutually beneficial. In particular, an integrated planning effort that allows the cavern engineers to incorporate discrete research tasks aimed at improving cavern design and construction technologies, within the scope of the DUSEL experimental umbrella, may significantly enhance the viability of cavern-based physics experiment, such as the Long Baseline, and advance the state-of-the-art in cavern engineering. 1 INTRODUCTION For over half a century the particle physics community has used underground space to house major experiments. These underground experiments have allowed the physicists to probe into the fundamental nature of matter.To support this research, tunnels up to 27 km long have been bored and caverns up to 40m in span excavated. The overburden not only provides shielding to protect the surface environment from the radiation emitted by the research equipment, but also serves to range-out the cosmic particles that inhibit the ability of detection systems to uniquely identify the most delicate particle signatures. of a Long Baseline experiment. 2 KEY CAVERN DESIGN REQUIREMENTS Although most design criteria for physics caverns are somewhat comparable to those of other underground facilities built to fulfill more conventional functions associated with civil or mining applications, the size and depth of the Long Baseline cavern will present engineers with some unusual, if not unique, design challenges. In particular, as currently scoped, these caverns are, without exception, very large.

Abstract Since the formation of the International Society for Rock Mechanics (ISRM) Commission on Underground Research Laboratory (URL) Networking in 2011, we have attended and organized URL-related meetings. During 2013 -2014, the gatherings of Commissioners include the 3 SINOROCK, 47 ARMA symposium, 13 TAUP (Topics in Astroparticle and Underground Physics) conference, 2013 AGU annual fall meeting, 2013 EUROCK symposium, 4iDUST (inter-Disciplinary Underground Science and Technology) conference, and the 8 ARMS (Asia Rock Mechanics Symposium). The 2015 planned activities include the 4 URL Workshop associated with the 13 ISRM Congress. Recent progress in planned heater tests in radioactive waste URLs, designs of large excavations in deep physics facilities, and other underground studies are reviewed in this article. Rock mechanics findings and multi-disciplinary studies are among topics of interest to the ISRM Commission. Heater tests for better understanding of the coupled thermal-hydro-mechanical-chemical processes are of interest to radioactive repository assessments and for other thermal storage and geothermal production projects. Large excavations in physics laboratories are driven by the needs associated with designing and housing next generation of experiments to detect rare events. Some existing physics laboratories are interested to use available spaces for geo-sciences studies, including microbiological research for deep life. We review the progress in these topics and welcome inputs on case histories and planned developments in URLs. The inputs from the geo-engineering and rock mechanics communities are essential for our continuing efforts of the ISRM URL Networking Commission.. 1. INTRODUCTION An Underground Research Laboratory (URL) Workshop was held on September 11, 2011, in Beijing, China, in association with the 12 International Society for Rock Mechanics (ISRM) Congress. This was the 3 URL Workshop, and it follows the 1 URL Workshop on 2003 in Johannesburg [1] and the 2nd URL Workshop on 2007 in Lisbon. This 3 URL Workshop had 22 lectures in 5 sessions. The ISRM URL Networking Commission was formed after this URL Workshop. In this paper, we reviewed primarily presentations in meetings after the 3 URL Workshop. An early literature review was presented at the 2010 ARMS in New Delhi [2] of URL activities before the 3 URL Workshop. An overview of the 3 URL Workshop lectures and other subsequent meeting sessions in following years are presented in 2015 in the 13 ISRM Congress [3]. Underground studies have been conducted primarily either to evaluate the capacities of different formations to isolate wastes or to explore resources at depths. Many researches are conducted in sites for radioactive waste assessments to project over geological time scales, for physics detectors for rare event detections, for multi-disciplinary collaborations, and for energy resources productions and for environmental isolations. For the ISRM URL Networking Commission, we use the term URL for any facility dedicated to all these research activities. We focus on recent advances in understanding various processes conducted in URLs. The ISRM URL Networking Commission dedicates to evaluate these studies in various workshops and meetings, including the series of Asian Rock Mechanics Symposia (ARMS), EUROCK annual meetings, regional ISRM-sponsored symposia, American Geophysical Union (AGU) meetings, American Physical Society (APS) meetings, and other topical meetings organized after 2011. We focus on recent advances in understanding various processes conducted in URLs, and on known plans and designs for expansions.
