摘要
随着开采深度的增加、开采范围的扩大和开采强度的加大,矿井发生煤矿冲击地压事件呈现明显的上升趋势。近年来,我国不断发生煤矿冲击地压事故,给矿井安全生产带来了严重的挑战。在这样的背景下,做好煤矿采区冲击地压安全监测工作就显得尤为重要。本文对梁宝寺矿3400采区煤层在工作面开采中冲击地压的形成进行分析,对危险区域进行了划分,并提出了在开采过程中通过卸压解除危害的具体防治措施,为开采煤层防止冲击地压,保证矿井安全生产提供了有效的技术支撑。
With the increase of mining depth, the expansion of mining scope and increase of mining intensity the event of which coal mine occurs rock burst shows obvious rising trend. In recent years, China has constantly roc k burst accident of coal mine, poses a serious challenge to the mine production safety. In this context the security monitoring of which do a good job of rock burst in mining areas of coal mine is particularly important. In this paper the formation of rock burst is analyzed in the face mining of 3400 mining area in Liangbaosi coal mine, the danger zone is divided, and in the mining process by pressure relief relieving hazards prevention and control measures are proposed, for preventing rock burst in mining coal seams and ensuring mine safety production provide effective technical support.
