Research on Safety Management of Fully Mechanized Mining Face with Stratified Broken Roof under Large Inclination Angle
The fully mechanized mining face with stratified broken roof under large inclination angle mainly faces problems such as poor equipment stability,easy rolling of coal gangues,roof broken,difficult control of pseudo tilt and so on.During the stoping process,equipment anti toppling and anti slip management,roof management,anti gangue rolling management and others all constrain the safe and efficient production of the working face.By analyzing the above-mentioned technical and management difficulties encountered during the stoping process of the ji formation west wing re-mining working face in Pingmei Holding Xiangshan Mine,the equipment type selection and mining scheme are determined,and anti toppling anti slip measures for the coal mining machine and hydraulic support,strengthened management measures for the broken roof,and anti gangue rolling measures for the working face etc,are formulated,which avoid problems such as support tilting,conveyor sliding,roof leakage,injury from rolling gangues and so on during the production process,and achieve safe and efficient production of the working face.
