针对冲击地压影响因素多样性而难以准确评价的问题,在某一工作面开采前期采用多因素耦合法,对煤岩结构、地质结构、覆岩空间结构运动和预留煤柱等5个影响因素的可能影响范围和程度进行危险性分析;并划分出工作面的危险区域及其程度;最后,在开采过程中采用微震监测的方法分析5个因素所影响的区域,并分别进行验证;结果证明运用微震监测和多因素耦合理论进行分析,可以有效地实现对冲击地压的预测预警。
In view of the difficulty of accurately evaluating the influence factors of rock burst, the influence of rock mass structure, geological structure, spatial structure movement of overlying strata and reserved coal pillar are influenced by the multi-factor coupling method in a certain working face before mining. Finally, during the mining process, microseismic monitoring method was used to analyze the five affected areas and verify the results separately. Results It is proved that the application of microseismic monitoring and multi-factor coupling theory can effectively predict and predict rockburst.
