Research status and prospect of mining catastrophic response ofrock mass under the influence of fault

  • 摘要: 针对采动可能引起断层活化进而导致工程灾害,从断层形成机制、断层附近岩体采矿工程响应及致灾、大断层附近安全开采3个方面综述了断层影响下岩体采动灾害响应机制和规律研究现状。对煤矿开采尺度下断层形成的地质力学机制及区域原岩应力分布特征、断层对采动应力阻碍及传导作用机制、采动应力与断层相互作用下致灾机理、近断层煤炭安全开采与灾害防治等4方面的进一步研究提出了展望;将断层形成和运动过程中应力场、能量场与采动相结合,可以更好地研究断层影响下岩体采动灾变响应,利用断层特性可以防治相关矿山灾害,以期为认识断层影响下岩体采动灾变响应及灾害预防提供技术支持。

     

    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.
