水峪煤矿十采区开拓巷道变形及支护技术研究

On the Roadway Deformation and Support Technology of No.10 Mining Field of Shuiyu Coal Mine

水峪煤矿十采区第二回风巷为水峪煤业十采区主要回风大巷,部分区段巷道因压力大出现顶帮严重变形及底鼓现象。分析巷道围岩性质及巷道支护技术,进一步改善巷道支护参数,以延长巷道维修时间及减少巷修费用。

The second air return roadway of No.10 mining field of Shuiyu Coal Mine is the main air return roadway of No.10 mining field of Shuiyu Coal Mine, some sections of which are of severe deformation of roof and surrounding rock and floor heave under high pressure. This paper analyzes the properties of the surrounding rock and roadway support technology to further improve the roadway support parameters, in order to extend the roadway maintenance time and reduce roadway repair costs.
