“…The deformation observed at the cavern was within acceptable limit. Hoek and Moy (1993) have discussed about the yielded zone of powerhouse caverns located close to the toe slope and gave recommendations to adjust the rock support based on the actual stability condition during cavern excavation. Similarly, all yielded bolt elements were restrained within the disturbed zone, which constitutes 1/2 to 1/3 of rock bolt lengths in cavern roof and walls.…”

Evaluation of an underground powerhouse cavern's stability is a challenging task and needs to be carried out carefully by taking care of its location, orientation and dimensioning. This article deals with the stability evaluation of a large underground powerhouse cavern, which is located at the toe of the valley side slope where the depth varies between 59m (minimum) and 70m (maximum). The planned powerhouse cavern has a dimension consisting 130m length, 23m wide and 48 m high. The manuscript evaluates the extent of pre-construction phase engineering geological investigations of the project, discusses on the selection of input parameters and carries out assessment on the displacement conditions at the cavern and also assesses the extent of yielded zone at the toe slope. Finally, recommendations are suggested on the location and orientation of the powerhouse cavern, uncertainties involved in numerical analysis and boundary conditions for 2D and 3D models under gravitational field stress.

A passport to success in mineral mining is the detailed geomechanical information on enclosing rock mass and structure of a mineral deposit. These data are used as a framework for the rock mass stability estimation. These data are taken into account in critical decision-making on mine design, which finally determines the mine safety and performance. The authors review the current methods of acquisition of geotechnical data at the stage of geological exploration. The structural model is constructed for Shiraldzhin gold deposit in Kyrgyzstan. The structural modeling used the data of geophysical measurements in 6 boreholes. It is shown that construction of a geotechnical database helps design future parameters of a mining system. Geophysical borehole investigations have an advantage over the conventional coring techniques in terms of cost and accuracy. The geophysical borehole measurements using a borehole image scanner requires maintenance of borehole parameters: diameter not less than HQ; angle not less 55°; mouth casing down to bedding rocks. Finally, the major requirement is scanning to be accomplished immediately after drilling (within one day depending on rock stability).
