厚煤层综采工作面过背斜构造技术实践

Technical Practice of Over-anticline Structure in Fully-mechanized Mining Face of Thick Coal Seam

以汾西矿业集团水峪煤矿61123综采工作面为背景,通过分析工作面顶板情况,确定合理的加强支护方式,以确保工作面安全通过背斜构造,同时确定合理的调架方式,以解决由于构造致使工作面顶板破碎和支架倾斜的问题,最终使工作面安全通过该构造。

Taking the 61123 fully mechanized mining face of Shuiyu coal mine of fenxi mining group as the background, through analyzing the roof situation of the working face, the reasonable strengthening supporting way is determined to ensure the safety of the face passing through the anticline structure, and the reasonable way of adjusting the frame at the same time. In order to solve the problems of roof breakage and support tilting due to the structure, the working face can pass safely through the structure.
