摘要
了解煤矿地下岩层的地应力情况可以帮助评估矿井工作面和巷道的稳定性,从而为安全生产提供重要参考。本文基于应力解除法对陈家山煤矿井下地应力状态及分布规律展开研究。依据研究结果,建议采用巷道轴向与最大水平主应力平行布置方式,有利于巷道顶底板的稳定。
Understanding the geostress of underground rock layers in coal mines can help evaluate the stability of mining faces and tunnels,providing important references for safety production.This article conducts research on the underground stress state and distribution law of Chenjiashan coal mine based on the stress relief method.Based on the research results,it is recommended to adopt a parallel arrangement between the axial direction of the tunnel and the maximum horizontal principal stress,which is conducive to the stability of the roof and floor of the tunnel.
