综采工作面过高应力区技术措施应用分析

Application Analysis of Technical Measures for Fully Mechanized Working Face Passing Through High Stress Area

本文针对山西某矿井8306工作面由于受断层及上覆采空区煤柱叠加应力影响,而导致工作面机道顶板破碎、应力集中的难题,制定了综采工作面过高应力区技术措施,确保了工作面安全回采,取得了显著效果。

In view of the problem that 8306 working face of a coal mine in Shanxi is affected by the superimposed stress of fault and overlying goaf coal pillar,which leads to the broken roof and stress concentration of working face,this paper formulates the technical measures for fully mechanized working face to pass through the high stress area,ensures the safe mining of working face,and achieves remarkable results.
