库兹巴斯所属的各矿井广泛应用掩护式开采方法来开采急倾斜厚煤层。这种方法是由H.A.契那卡尔教援首创的。1936年曾在三号矿井(吉谢列夫斯克)对掩护支架进行了试验。1939年在“考柯克苏”矿井(普罗考比耶)进行了试验,1940年又在吉谢列夫矿区的其它矿井进行了试验。通过这些试验,证明了采用这种方法的合理性。第一批试采是成功的,每月从一个掩护式工作面采出的煤达到5500吨,以后,掩护式工作面的生产能力得到大幅度提高。
Kuznets belongs to the mine extensive use of cover mining method to the mining of steep thick coal seam. This method is pioneered by H.A. Chinalka. The scaffolding was tested in 1936 in the third mine (Jiseppelvsk). A test was carried out in the “Cocoksu” mine (Prokobyjaya) in 1939 and in 1940 at the other mines in the Jiselev area. Through these experiments, the rationality of adopting this method is proved. The first batch of trial mining was successful, with 5,000 tons of coal being mined monthly from one screening working face. In the future, the production capacity of the covered working face has been greatly increased.
