高阳煤矿特厚煤层巷道支护研究
|
摘要
为了解决汾西矿业(集团)有限责任公司高阳煤矿二采区区段煤柱减小后工作面顺槽的支护问题,以该矿二采区9-10-11号煤层21107工作面运输顺槽为工程背景,根据其煤层及顶底板情况,提出"锚杆+金属网+钢筋梁+锚索"联合支护方案。将该联合支护方案运用于现场实践中,取得良好支护效果。
In order to solve the problem of supporting the working face trench in the second mining area of Gaoyang Coal Mine, Fenxi Mining(Group) Co., Ltd. after the reduction of coal pillars, a combined support scheme of "bolt +metal mesh + steel bar beam + anchor cable" is proposed based on the engineering background of 21107 working face transportation trench in No. 9-10-11 coal seam of the second mining area of Fenxi Mining(Group) Co., Ltd. The combined support scheme has been applied to field practice, and good support effect has been achieved.
