As large open pit slopes increase in depth, with feasibility studies now underway for slopes over 1.4 km, it is becoming increasingly necessary to investigate nonconventional rock slope failure mechanisms. In massive brittle rock slopes, both natural and engineered (e.g. open pit mines), potential failure surfaces are often assumed as fully persistent continuous planes [1]. However, this is not the case for most slopes and where a certain percentage of rock bridges are present along the discontinuity, which increases the stability, ignoring their existence may lead to conservative design Many authors have demonstrated the importance of rock bridges on the stability of slopes [2-8].

Multi-stage stimulation has become the norm for unconventional reservoir development. However, one of the primary obstacles to optimizing completions in shale reservoirs has been the lack of hydraulic fracture models that can properly simulate complex fracture propagation often observed in these formations. Different modeling approaches recently have been developed to simulate complex fracture networks in naturally fractured formations [1, 2, 3, 4, 5, 6, 7].

For the geosequestration of CO2, fluid injection is the triggering force for the hydro-mechanical change of reservoir, and ground heaving and shear slip of fracture are critical issues for the stability CO2 reservoir. When a fluid is injected into the reservoir, the increased pore pressure makes the ground heave. For example, at the In Salah project in Algeria, approximately 5 mm/year of ground heaving was observed, with the affected area being several kilometers from the injection well [1].

The Statfjord field is a large oil field located in the Northern part of the Viking Graben in the North Sea. The field has been in production since 1979 and has recently entered its late life phase. Since January 2009 the water injection has stopped and the field development went towards deep depressurization to produce solution gas. This requires the production of large amounts of water, approximately 800 MillionSm3. Initially one of the options for the disposal of the produced water was through injection into overlying shallow aquifer reservoirs, the Utsira and the Hordaland formations. This article presents the results and the interpretation of these well tests and how these test results influence the design of the water injection scheme. To increase the confidence of our interpretation, we compare them with results from other wells and independent testing methods.

The TRJV mine consisted of two major segments; the Getchell Main Underground (GMU) mine and the Turquoise Ridge (TR) mine segment. The Getchell underground segment is currently shutdown. The primary ground control uses bolting, mesh, and shotcrete. It includes the use of cemented rock fill and a quick mining sequence to minimize ground exposure time and unraveling ground.

In the mining and civil engineering industries, slope stability analyses have become essential to ensure site safety, maximize ore removal, and limit interruptions to production. Care should be taken however as these programs will all compute different results and usually produce varying individual slip surfaces. The factor of safety values obtained from these programs must be carefully analyzed with the realization that the limit equilibrium method (LEM) and the shear strength reduction technique (SSR) may produce FOS values different from one another. As noted, Stead et al (2006) [1] recommends combining the use of both the LEM and numerical modeling techniques to ensure maximum certainty and utilize the advantages to both methods.

In large-scale granular systems, the material behavior depends on the grain-scale dynamics, which in turn evolve with changing large-scale conditions. As a result, the large-scale and the grain-scale are inextricably linked. Despite this multiscale nature of the material, it is standard practice to simulate systems of practical interest by continuum mechanics approaches such as the finite element method (FEM) [1, 2]. These approaches typically require a continuum mechanics representation of the constitutive relationship between stress and deformation. Because this representation must be written in continuum form, it lacks explicit representation of the grain-scale dynamics [1, 3]. In contrast to continuum mechanics approaches, discrete approaches such as the discrete element method (DEM) capture grain-scale phenomena [4, 5].

The effective properties of random heterogeneous materials are usually considered using either the concept of a representative volume element (RVE) or a repetitive unit cell (RUC) with a random arrangement of reinforcement. The approaches naturally raise questions about the suitable size of the RUC or RVE and the corresponding boundary conditions used to solve the boundary value problems. The approach advocated in the present paper is based on Maxwell''s idea [1] that a cluster representing the microstructure of the material, being embedded into an infinite space with the properties of the matrix, affects the fields at large distances from the cluster in the same way as an equivalent inhomogeneity whose properties are equal to the effective ones. Maxwell [1] did not account for the interactions between the constituencies in the cluster and for their geometrical arrangements. In [2, 3], Maxwell''s concept was modified to evaluate the effective properties of linearly elastic, transversely isotropic, unidirectional multi-phase composites with perfect and imperfect interfaces. Unlike in Maxwell''s original method, the key aspect of the approach was to precisely account for the interactions between all the constituents in the cluster that represent the material in question. The shapes of the microstructural elements considered in these papers were circular cylinders.

The advantage of rebar and shotcrete composite backfill fences are the ease in construction, high strength and limited footprint within the mine. This paper discusses the critical aspects of design, the strength of the fence and the imposed load of the backfill. Construction of these fences is typically done by embedment and grouting of rebar within the walls, the construction of a rebar lattice, placement of adhering surface, and the spraying of the shotcrete to the desired thickness. The effect of each of these steps to the behavior of the fence is discussed from practical examples. The effect of the placement of backfill from the point of imposed loads on the barricades is investigated. The effect of fill rate, backfill pulp density and fill heights are discussed. The thickness of shotcrete and the depth of embedment of rebar within are discussed

The composite rebar, shotcrete barricade fence is a common barricade for confining paste backfill within a mined stope [1, 2, 3]. The advantages of this barricade are the limited footprint, that it can be constructed using typical ground control materials at a minesite, and that it is strong in comparison to other barricades [4]. Typically, the composite barricade is used in narrow vein with Good to Fair Rock Mass. Cayeli Mine and Goldcorp’s Red Lake Mine are two examples. The composite fill barricades are now being used in mines where the host rock is heavily altered, and the use of paste is required to provide a competent back; Yukon Zinc Corp’s Wolverine Mine and Newcrest’s Goswong/Kencana Mine are two examples of these operations. Two key design aspects to consider with the use of the composite fill barricade; are the construction of the fill barricade and the imposed load placed on the barricade by the backfill.
