The Experimentation and Research of the Bolting of the Back of Ashele Copper Mine

In allusion to the problem of the unstabilty of the direct back of the 650M middle part of ASHELE copper mine and the complex geologic condition of the contiguity zone of mine rock, the experimentation and research of long anchor cable, spray anchor net and multi-technology combined bolting of slurry poring were developed and a preferably effect has been gained. In the meantime the disposal way of the ground pressure and its bolting has been brought forward.
