两次采动影响下巷道底鼓实测对比分析

Measurement and Comparative Analysis of Floor Heave of Roadway under the Influence of Double Mining

本文针对高河煤矿目前面临的巷道底鼓研究成果的缺失,以E2305工作面胶带巷为例,对该巷道经历E2303工作面和E2305工作面两次采动影响的巷道底鼓变形进行实测对比分析。结果显示,E2305胶带巷受双采动影响后,巷道底鼓现象严重,需要采取有效的巷道补强支护进行控制。本文研究成果为高河煤矿巷道底鼓研究和控制提供理论参考。

In view of the lack of research results of the roadway floor heave currently in Gaohe Coal Mine,taking the E2305 working face belt lane as an example,the floor heave of roadway under the influence of double mining in the E2303 working face and in the E2305 working face is measured and compared.The results show that after the E2305 tape lane is affected by double mining,the floor heave of roadway is serious,and it is necessary to take effective roadway reinforcement support to control the bottom drum phenomenon of the roadway.The research results are intended to provide a theoretical reference for the research and control of the tunnel bottom drum in Gaohe Coal Mine.
