摘要
针对复合型坚硬顶板的六采区,通过对工作面生产过程的矿压显现进行了全面观测和力学分析。根据复合型坚硬顶板条件下工作面的矿压显现规律进行深孔爆破卸压设计,并应用工作面的回采生产,在生产过程中消除了冲击地压现象,实现了回采工作面的安全生产,提高区域资源回收率,延长矿井服务年限2 a,投资小,效果好,为矿区的社会稳定带来巨大的社会效益。
In view of the compound hard roof of Six picks the area, through carrying on the comprehensive servation and the mechanics analysis appeared to pressure appears of the working face production process. We carry on the hole demolition uploading pressure design according to the rule of pressure appears of working face under the compound hard roof condition, and use the working face pick. It eliminated the impact geostatic pressure phenomenon in the production process, realized the safety in production of working face, enhanced the region resources returns - ratio, lengthened the mine service years two years. It invested slightly and gained good effect, and brought the huge social benefit for mining area society stabilization.
