库兹巴斯各矿井每年需要掘进1500km左右准备巷道,其中开拓和采准巷道为931km。采用机械化装岩的准备巷道掘进量为856km,其中用掘进机掘进的巷道为526km。机械化装岩比重为82.7%,采用掘进械机掘进的巷道占50.8%。这样的准备工作指标不能保证均衡准备回采工作面,从而使库兹巴斯公司各矿井无法完成采煤计划。因为矿井有大量手工作业的辅助工作量,虽然采取了增加工人的措施,但仍未能解决增加煤产量的问题。在用掘进机和钻爆法掘进准备巷道的过
Kuzbass mines each year need to tunnel about 1500km to prepare the roadway, of which the development and acquisition of the roadway is 931km. The amount of tunneling for mechanized rock loading is 856 km, of which 526 km is for tunneling with TBM. The proportion of mechanized rock loading is 82.7%, and the roadway using tunneling machines accounts for 50.8%. Such preparatory work does not guarantee a balanced preparation for mining face, thus making it impossible for Kuzbasi mines to complete the coal mining plan. Because of the large amount of auxiliary work carried out by hand in mines, the measures to increase workers have not yet solved the problem of increasing coal production. In the use of roadheader and boring blasting tunneling preparation for the over
