耦合支护技术在深井、高水压软岩巷道中的应用研究

Application of Coupling Supporting in Deep Mine Soft Rock Roadway with High Water-pressure

为了解决深井支护难的问题,焦煤集团赵固二矿在深井高水压构造应力场巷道采用耦合支护技术,不仅有效控制了围岩的变形,保证支护体不被破坏,减少巷道翻修,保证矿井如期投产,而且大大改善了井下巷道面貌,保证了矿井的安全生产。

In order to solve the support problem of deep mine,Zhaogu No. 2 Coal Mine in Jiaozuo Coal Group used coupling support technology in deep mine roadway located in high-water pressure tectonic stress field. The deformation of surrounding rock was effectively controlled, the supporting body was ensured not to be destroyed, tunnel overhauls were decreased, the shaft also was put into production as scheduled. The coupling support technology will improve environments of tunnel greatly, and it can guarantee the safe production of the mine.
