Joint control method of surrounding rock of coal seam roadway under the vision of green ecology
Due to the serious deformation and damage of surrounding rock in coal seam roadway and the great difficulty in control,under the advocacy of green ecology,the joint control technology for surrounding rock in coal seam roadway was studied.Based on the mechan-ical information and supporting structure material information of surrounding rock in coal seam roadway,the stress distribution in the mining face of the surrounding rock in coal seam roadway was analyzed and simulated,and a simulation model for surrounding rock in roadway was constructed using FLAC method.Taking the section of a coal seam roadway in a certain area as the research objective,we achieved the reinforcement of the roof of the surrounding rock of the coal seam roadway,and completed the research on the joint control technology of the surrounding rock of the coal seam roadway under the advocacy of green ecology.The experimental results show that un-der the maximum pressure of 10 MPa,the strength of C30 in the filling body of the retained roadway reaches the design index.The plas-tic range of roof surrounding rock is small,and the designed joint control technology of surrounding rock can improve the stability of sur-rounding rock in coal seam roadway.
