Research and Application of Rotating Mining Technology in the Filling Working Face of Jingu Mine
Aiming at the difficult problem of irregular layout of the stoping working face and the need for rotating mining in the No.11 coal seam of Jingu Mine in Guxian of Shanxi Province,which is affected by the old kiln goaf damage area,ground village buildings and others,taking the 11101 filling working face as the engineering background,this paper studies the rotating mining technology of the filling working face using theoretical analysis and on-site measurement methods.In order to improve the safety and implementation efficiency of rotating mining,a rotating mining technology scheme is proposed to advance the construction of the roadway allocation at the north side of the 11101 tape groove corner at the end of the rotation of the working face,which safely and efficiently achieves a large angle rotation mining of 48°-50°.The method of construction rotating mining and roadway allocation is suitable for the rotating mining project of the No.11 coal seam in Jingu Mine.It is successfully applied to the 11101 filling working face and promoted throughout the mine,greatly improving the coal recovery rate and mine production efficiency.
