摘要
综采作业面过断层期间,顶板破碎性较强,实现对过断层期间作业面顶板的有效控制意义重大。以此为着手点,结合工程实际,对空顶区安全防控和回采期顶板管理进行了综合分析,希望能够为其他矿井相似工程的开展提供借鉴和参考。
During the overfault of fully mechanized mining face, the roof fracture is strong, and it is of great significance to rea-lize effective control of working face roof during fault crossing. Taking this as the starting point and combining with the enginee-ring practice, this paper made a comprehensive analysis of the prevention and control of the empty top area for safety and the roof management during the stoping period, in the hope of providing reference for other similar mine projects.
