摘要：
Reliable prediction of rock mass deformation, mine stability, mine water inflow and mine gas emission is not only essential for improving mine safety and reduction of coal production costs, but also important for the assessment of environmental impact of mining. This prediction requires the accurate simulation of complex, highly non-linear and irreversible processes including the mechanics of rock deformation and failure due to coal mining and the consequent water flow and gas desorption and flow.
