ABUTMENT PRESSURE DISTRIBUTION AND ITS TRANSFER LAW IN FLOOR OF DEEP ISOLATED FULLY-MECHANIZED MINING FACES USING SUBLEVEL CAVING
|
Abstract:
Based on the mining condition of No.4403 isolated fully-mechanized mining face with the sublevel caving in Dongtan Coalmine,the transfer of the abutment pressure in the floor is studied. The results provide a basis for controlling additional roadway deformation efficiently and ensure the regular production of the mine.
