Abstract:
According to the engineering disasters resulting from fault activation caused by mining,the research status of mining rock mass catastrophic response mechanism and law near faults is summarized.It includes fault formation mechanism,rock mass catastrophic response to mining engineering near faults and safety mining near large fault.Four aspects of further researches are prospected,including the geological mechanics mechanism of fault generation and original stress distribution characteristics of rock mass near faults in mining engineering,obstacles and conduction mechanism of fault on the mining induced stress,disaster-causing mechanism induced by the combined actions of mining stress and fault and coal safety mining and disaster prevention near fault.It is better to study the mining rock mass catastrophic response mechanism influenced with fault considered both the mining engineering and stress field,energy field during the process of fault formation and movement.The fault characteristics can be related to the mine disaster prevention.It is expected to provide technical support for rock mass disaster response and disaster prevention in mining under the influence of fault.
