孟村煤矿中央带式输送机大巷层位调整技术实践

Practice of horizon adjustment technology of central belt conveyor roadway in Mengcun Coal Mine

针对孟村煤矿中央开拓大巷布置在严重冲击地压煤层中的现状,以中央带式输送机大巷为例,通过分析大巷工程概况及冲击地压显现特征,对巷道层位调整进行了技术分析,形成科学的中央带式输送机大巷层位调整施工、充填及防冲方案,在该方案的指导下中央带式输送机大巷已顺利完成层位调整施工约500 m,可为类似工程条件下的巷道层位调整提供借鉴。

In view of the current situation that the central development roadway of Mengcun Coal Mine is arranged in the coal seam with serious rock burst,taking the central belt conveyor roadway as an example,through the analysis of the general situation of the roadway project and the characteristics of rock burst,this paper makes a technical analysis on the roadway horizon adjustment,and forms a scientific construction,filling and anti-rockburst scheme for the horizon adjustment of the central belt conveyor roadway.Under the guidance of this scheme,the central belt conveyor roadway of Mengcun Coal Mine has successfully completed the horizon adjustment construction of about 500 m,which provides reference for roadway horizon adjustment under similar engineering conditions.
