... the heat transfer modeling can be found in [4]. 2. FLUID FLOW & HEAT TRANSFER A schematic view of heat extraction from a fracture or a fracture zone in rock is illustrated in Figure 1. With only a few exceptions such as the finite element solution by [5-7] and the boundary element model in [8], the heat...

.... The study concluded that it was feasible to extract a 90 m high by 70 m wide destress slot in front of the shaft in order to stress shadow and protect it during subsequent mining of the shaft pillar ore. The study was accepted, a comprehensive instrumentation program was put in place and detailed planning...

... following system installation, seismic velocity, stress and geomechanical data, indicated that the majority of microseismic activity was related to the development of a large stress arch over the mined out panels. During extraction of the 400 panel a back failure in previously cable bolt supported ground...

... ABSTRACT : This paper describes an integrated program of rock mass classification, instrumentation, and numerical modelling used at the David Bell Mine. This program was used as a planning tool so that the extraction of a critical sill pillar in the mine could be successfully achieved...
