摘要
神华宁夏煤业集团清水营煤矿属于"三软"煤层开采,软岩巷道的支护问题严重制约了矿井的安全生产,加剧了采掘接续紧张。本文结合地质资料及现场实际情况,提出了切实可靠的支护方案,有效地提高了巷道的稳定性,增加了巷道施工的安全性,这对软岩条件下煤矿安全开采具有重要意义。
Shenhua Ningxia Coal Industry Group Qingshuiying Coal Mine belongs to the soft coal seam. Soft rock tunnel supporting seriously restricted the safety production of mine, intensified mining tension. Combined with actual situation, this paper puts forward the practical and reliable support program, effectively improves the stability of roadway and increases the safety of tunnel construction. It is of significance to coal mine safety under the condition of the soft rock mining.
