煤矿深部开采软岩巷道支护措施分析

Analysis on Support Measures of Soft Rock Roadway in Deep Mining of Coal Mine

伴随着开采深度的加大,为了提升煤矿的安全性和稳定性,就要对深部开采软岩巷道予以合理性支护处理,减少巷道变形破坏以及围岩不稳造成的损失,打造安全高效的煤矿开采环境,实现经济效益和社会效益的双赢。本文结合案例分析了煤矿深部开采软岩巷道变形控制要点,并结合数值模拟分析了相应的最佳支护模型。

With the increase in mining depth,in order to improve the safety and stability of coal mines,it is necessary to rationally support the soft rock roadway in deep mining,reduce the roadway deformation and damage and the loss caused by the instability of the surrounding rock,and create a safe and efficient coal mining environment to achieve win-win economic and social benefits.This paper analyzes the key points of deformation control of soft rock roadway in deep coal mining in combination with cases,and analyzes the corresponding optimal support model in combination with numerical simulation.
