摘要
山西永聚煤业有限公司主采的10#煤层顶板为裂隙溶洞极度发育石灰岩,巷道难以稳定控制,矿方和太原理工大学共同研究,通过工程检测和三维数值计算与拟合研究,探索合理有效地巷道支护方式。
The roof of 10# coal seam mainly mined in Shanxi Yong Ju Coal Co. Ltd, is the limestone with extreme development fracture cave, the roadway supporting is difficult, by jointing research with Taiyuan University of Technology, compared the result of the engineering test and 3D numerical calculation, and explored the reasonable and effective roadway support method.
