近距离煤层停采线内错6 m支护方案的研究实践

Research and Practice of Offset 6m Support Scheme in Close Coal Seam Stop Line

充分分析停采线变化前后矿压显现规律,对比研究支护方案,使得停采线前移14 m。研究结果为近距离煤层下回采工作面停采线内错6 m时,采用何种联合支护方式能够有效支护巷道顶板这一生产难题提供了可靠的参考依据。

The ore-pressure pattern before and after the change of stoppage line was fully analyzed,and the supporting scheme was compared,which made the stoppage line move 14 m forward.The results provide a reliable reference for the production problem of roadway roof which can be effectively supported by the joint support method when the stoppage line is offset 6 m under the close coal seam.
