陕西铅硐山矿业有限公司巷道地压分析

Analysis of Roadway Pressure in Shaanxi Qiandongshan Mining Co.,Ltd.

随着铅硐山井下开采逐渐向深部延伸,采矿受采空区、断层等地压影响越来越大,部分中段巷道出现片帮、顶板开裂、底鼓等现象。本文主要通过建立模型,进行深入研究、分析,得出巷道应力分布,获得各中段巷道地压显现规律。

With the roadway mining of Qiandongshan gradually extending to the deep, the mining affected by the goaf, fault and other ground pressure is growing, some of the middle section of the roadway appears spalling, roof cracking, bottom drum phenomenon. In this paper, through the establishment of the model, in-depth study and analysis, it obtained the stress distribution of roadway, access to the middle of the roadway pressure law.
