巷道锚杆支护的力学稳定性模拟实验

Simulation of Mechanical Stability of Roadway Bolting

巷道支护是煤矿开采中的重要环节。如何有效地对煤巷进行支护成为了困扰煤矿企业的难题。文章利用锚杆支护模拟实验分析了回风巷道和辅助运输巷道的围岩应力分布和巷道移动量,为今后巷道支护工作的开展提供了可靠的实验依据。

Roadway support is an important link in coal mining, How to effectively support ior coal roadways has become the puzzle problems in coal mine enterprises. In the papaer, the surrounding rock stress distribution and roadways elisplacement of the air return roadway and auxiliary transportation roadway are analyzed by using the bolt support simulation experiment. The reliable exoerimental basis are orovided for the future roadway suooort.
