Practical research on supporting technology for continuous mining and filling working face branch roadway
In order to solve the problems of large subsidence of the roof and continuous deformation of the branch roadway surrounding rock in the continuous mining and filling working face,taking the No.1101 working face in the No.1 filling area of Limin Mine as the engineering background,according to its production geological conditions,a numerical calculation model was established through the physical and mechanical properties of the branch roadway surrounding rock in the continuous mining and filling working face.The stabil-ity of the branch roadway surrounding rock under different mining methods,production cycles,and surrounding rock states was compre-hensively analyzed,and the differentiated supporting technology for the continuous mining and filling branch roadway in Limin Mine was determined.The industrial test results on site show that the application effect of this technology is good,providing reference and inspira-tion for the filling mining process of each roadway under similar conditions.
