孟津煤矿西翼第二中部车场巷道变形特征及原因分析

Characteristics and Reason Analysis of Tunnel Deformation at Second Middle Section in West Wing of Mengjin Coal Mine

随着巷道掘进深度的不断增加,工程地质环境不断恶化,深部岩巷变形和破坏现象越来越严重。通过对现场工程地质条件的调查,分析了孟津煤矿西翼第二中部车场巷道变形破坏现象,找出了变形破坏的原因。

With tunnelling depth escalation, the engineering geology environment worsens inceasingly, the phenomenon of the deep rock road deformation and destroy are more and more seriouse. By the investigation to the scene engineering geology conditions, analyses the phenomenon of tunnel deformation and destroy, foinds out the destructive cause of deformation at second middle section in west wing of Mengjin Coal Mine.
