摘要
余吾煤业井田地质条件复杂,断层带分布范围较广,基于此,开展了余吾煤业断层构造区巷道围岩稳定性控制研究。通过KDZ1114-6A30矿井地质探测仪对断层产状进行现场勘探,并利用ARAMIS M/E微震定位设备对断层构造与采掘活动之间的影响关系进行分析研究,提出了采用锚-喷-注三重加固方案来提高巷道围岩的完整性和稳定性,进而起到防治冲击地压的作用。研究结果为断层构造区工作面的安全高效回采提出了一种新的监测和防治思路。
Because of the complicated geological conditions and wide distribution of fault zones,the stability control of surrounding rock in the coal mine fault structure area is carried out. The KDZ1114-6A30 mine geology detector field exploration of fault occurrence,and to analyze the influence between faults and mining activities using the ARAMIS M/E microseismic positioning device,the anchor-Spray-note three heavy reinforcement scheme to improve the integrity and stability of the surrounding rock,which leads to the prevention of rock burst effect. The results of this study provide a new method for monitoring and controlling the safety and high efficiency of the working face in the fault zone.
