【Abstract】 Based on the failure mechanism and characteristics of soft rock drifts in deep mines, this paper introduced the basic theory of supporting and reinforcing technology of the soft rock drifts by bolting and grouting. The technology was used to design the support para meters of the repaired soft rock drifts in Pingdingshan No. 12 Coal Mine, and good results were obtained. It by and large solved the supporting proble m of repaired soft rock drifts with high ground pressure in deep mines.更多还原
