摘　　要：为解决开拓大巷下开采造成巷道变形大,影响正常使用的问题,通过开采前影响分析,确定工作面开采方案,采用工作面膏体充填开采减沉、大巷分区段提前加固、大巷底板随鼓随卧底等措施,保证了轨道运输大巷的正常使用。In order to solve the problem that the roadway has great deformation and affects the normal use caused by mining under the open main roadway,through the analysis of the influence before mining,the mining scheme of the working face is determined.Measures such as reducing the subsidence of the working face by paste filling,strengthening the main roadway section in advance and undercover with the floor of the main roadway are adopted to ensure the normal use of the rail transportation main roadway.
