| Abstract: | The district sublevel gathering entry for haulage at +490m in Songshuzhen colliery lies in the crushed rock mass and its deformation is large,so its upkeep is difficult.In view of the condition,the controlling stress method using the relieving shot in the deep holes in the entry sides is applied to change the stress distribution,and the condtructional process and upkeep measures of the entry are improved,thus the ideal upkeep results of the entry and economic benfits are gained. |
