摘要
经对厚煤层矿山压力分析,确定巷道支护形式,并介绍煤层压力集中区送巷道支护遇到的技术问题和处理措施,解决了矿山压力对切眼巷的破坏,取得良好效果。
On the analysis of mine ground pressure of thick seams, roadway supporting mode was determined. The paper also introduced the problems and solutions in the supporting roadways in the pressure concentrated areas, which has achieved ideal effects in solving the destruction of the pressure on the open-off cut roadways.
