摘要
通过开采保护层区域防治冲击地压措施能有效解决灾害严重矿井生产接续与灾害治理工程相互制约的问题,优化生产布局、采掘部署,兴安煤矿经过开采四水平南23层二区一段后,23层工作面顶板能够断裂,应力得到充分释放,可判定准备回采21层工作面受下伏23层保护,通过回采实践,提供了可参考的依据,在今后的技术工作中值得广泛借鉴与推广应用。
The prevention and control measures of rockburst in the mining protective layer area can effectively solve the problem of mutual restriction between mine production continuity and disaster control engineering, and optimize the production layout and mining deployment. After mining the first section of zone 2, layer 23 in the south of level 4 in Xing’an Coal Mine, the roof plate of layer 23 working face can be broken and the stress can be fully released. It can be determined that the working face of layer 21 ready to be mined is protected by the underlying layer 23. Through mining practice, It provides a reference basis, which is worthy of extensive reference, popularization and application in the future technical work.
