迎采动面沿空掘巷受邻近工作面动压影响分析

The influence of adjacent working face on dynamic pressure of road-way driving along goaf

沿空掘进巷道有完全沿上区段采空区边沿掘进巷道和留窄煤柱掘进巷道两种之分。本文重点在于研究山西某矿掘进巷道受邻近工作面采动动压影响规律,实地对山西某矿2215轨道顺槽和2217回采工作面现场监测,通过巷道围岩变形量,绘出巷道围岩变形量折线图,得出了掘进巷道在受邻近工作面采动影响期间不同阶段特征,对巷道支护系数做出合理修正。

There are two types of roadway along the goaf in the goaf along the goaf, and the difference between the roadway and the roadway with narrow coal pillar. This paper focuses on the researeh of Shanxi mine roadway affeeted by adjacent mining face dy- namic pressure effect of the field of a mine in Shanxi, the 2215 track trough and 2217 working face by site monitoring, deformation of surrounding rock of roadway deformation of surrounding rock, draw the line graph, the excavation roadway under mining influ- ence during the adjacent working face the characteristics of different phases, make reasonable correction coefficient of roadway.
