陈家沟矿井设计生产能力 0 .45Mt/a ,矿井服务年限 65 .8a。该千米斜井主井筒长 969.5m ,倾角 2 5° ;副井筒长 1111m ,倾角 2 2°。两井筒均为锚喷支护。由于采用全断面一次爆破 ,大型抓岩机和箕斗排矸 ,特别是解决了斜井长距离管路输料难题 ,从而实现了掘进与支护平行作业 ,取得了斜井平均月进 94.2m的好成绩。
Chenjiagou mine design and production capacity of 0.45Mt / a, mine service life of 65 .8a. The main axis of the 10m inclined shaft is 969.5m in length with a dip angle of 25 °; the auxiliary shaft length is 1111m with a dip angle of 2 2 °. Both boreholes are anchor spray support. As a result of a full face blasting, large grasping rock machine and skip gangue, especially to solve the problem of long-distance inclined shaft well pipe feeding, so as to achieve the tunneling and supporting the parallel operation, the average inclined shaft made 94.2m Good grades.
