羊泉煤矿4401工作面揭露多条断层，在断层区域存在发生冲击地压的可能。本文采用应力监测、锚杆受力监测和钻屑法进行冲击地压监测，为本区域冲击地压的防治提供了保障。根据对4401工作面冲击地压监测方法的研究与应用，对下一步高复杂应力条件下煤层开采具有一定的指导意义。
羊泉煤礦4401工作麵揭露多條斷層，在斷層區域存在髮生遲擊地壓的可能。本文採用應力鑑測、錨桿受力鑑測和鑽屑法進行遲擊地壓鑑測，為本區域遲擊地壓的防治提供瞭保障。根據對4401工作麵遲擊地壓鑑測方法的研究與應用，對下一步高複雜應力條件下煤層開採具有一定的指導意義。
양천매광4401공작면게로다조단층，재단층구역존재발생충격지압적가능。본문채용응력감측、묘간수력감측화찬설법진행충격지압감측，위본구역충격지압적방치제공료보장。근거대4401공작면충격지압감측방법적연구여응용，대하일보고복잡응력조건하매층개채구유일정적지도의의。
Many faults were exposed in 4401 working face of Yang Quan coal mine, which has the possibility in the presence of rock burst in the fault region. This paper used the force of bolt stress monitoring, stress monitoring and method of drilling bits to monitor the rock burst, provided a guarantee for the prevention of rockburst in this area. according to the research and application of monitoring methods of rockburst in 4401 working face, has certain guiding signiifcance for the next step mining in the complex stress condition.
