Abstract:
According to the situation that some triangular coal cannot be produced in the final stage of the 301 fully mechanized working face of Changchun Coal Mine and it will continue to be detained in the normal driving direction, we explore the feasibility of the rotary mining scheme respectively from the technical experience, main equipment, personnel quality of labor and management level to calculate and introduce the roadway forms and methods of rotary mining in 301 fully-mechanized working face in detail. The successful implementation of the rotary mining scheme increases the service life of the working face and improves the recovery rate of the raw coal.
