摘要
地应力对巷道稳定性影响较大,确定合理的巷道布置方向应考虑地应力因素。在青云煤业公司东翼二采区实测地应力基础上,对东翼二采区回采巷道合理的布置方向进行了分析。
The crustal stress has great influence on roadway stability.The crustal stress should be considered in determining reasonable roadway layout direction.Based on the measured crustal stress in the second mining area of the east wing of Qingyun Coal Industry Company,this paper analyzed the reasonable layout direction of the mining roadway in the second mining area of the east wing.
