摘　　要：我国神东地区蕴藏着丰富的浅埋煤层,神东矿区在进行第一柱采煤层开采时曾采取房柱式开采,因此在进行第二柱采煤层开采时部分矿井存在工作面过上覆采空区及煤柱区的现象,这进一步引发了许多技术难题。据统计,由于上覆煤柱的影响,工作面在推进的过程中曾发生多起压架事件。如何确保工作面在煤柱区下的安全高效高产,是矿区亟需解决的技术难题。There are abundant shallow coal seams in Shendong area of China.Room and pillar mining was adopted in Shendong mining area when mining the first main coal seam.Therefore,during the mining of the second main coal seam,some mines have the phenomenon that the working face passes through the goaf and coal pillar area of the overlying room,which further causes many technical problems.According to statistics,due to the influence of overlying coal pillars,there are too many pressure frame events in the process of advancing in the working face.How to ensure the safety,high efficiency and high yield of the working face under the coal pillar area is an urgent technical problem to be solved in the mining area.
