千秋矿架空人车下山加固支护技术

Reinforce Supporting Technology of Aerial Ropeway Vehicle in Qianqiu Coal Mine

千秋矿是一座具有50多年开采历史的老矿,长期受采动影响,井下巷道变形破坏程度较高,其中架空人车下山巷道破坏较重,已影响人员运输。为解决架空人车下山巷道大面积严重失修的状况,从巷道布置与原岩应力方向关系、围岩条件、地质构造影响等方面考虑,并根据现场具体情况设计合理的支护方案,对下山巷道进行加固,其效果良好。

Qianqiu Coal Mine has been mined for 50 years.The degree of deformation and failure of roadway in mine was high because of mining influence.Destruction of aerial ropeway vehicles was heavier,which influenced personnel transportation of the coal mine.To solve serious disrepair of dip roadway of aerial ropeway vehicles,according to the situation of relationship between roadway layout and direction of surrounding rock stress,conditions of surrounding rock,aspects of geological structure,combined with the specific circumstances of rational supporting design scheme,dip roadway were reinforced effectively.
