海孜矿-1000m东轨道大巷锚梁网喷索注复合支护

Combined Support Technology Using Shotcrete and Bolting with Bar and Wire Mesh in-1000 m Eastern Track Roadway of Haizi Colliery

海孜矿随着开采水平不断延深,矿压不断增大,深井高地压巷道支护表现较为突出,巷道围岩治理较为困难,为此三水平岩巷开拓设计采用锚梁网喷索注复合支护技术,实施后巷道围岩变形得到有效控制,巷道支护状况发生了本质改变。

Aiming at the difficulties in the support of high-pressure roadway due to the extension of extraction and the increase of ground pressure in Haizi Colliery,the authors present the combined support technology using shotcrete and bolting with bar and wire mesh in the design of rock roadway development,which effectively controls the deformation of surrounding rock and improves the support quality.
