针对大同矿务局云冈矿井田北部断层等地质构造发育的特点，从开采方法和采煤工艺上进行了探讨和论证。提出了调斜工作面变俯斜为伪俯斜的开采方法；并就下坡过断层时采取加高采煤机滚轮架子和提前刹底支架前梁上衬道木和钢梁，加强前梁接顶防止漏顶等革新改造方法逐一分析和论证。 According to the characteristics of the geological structure such as faults in north of Yungang mine field in Datong Mining Bureau, the exploration and demonstration are made on the mining methods and coal mining technology. The mining method of adjusting inclined surface to be pseudo-inclined is put forward. In the case of going downhill over the fault, shelling the shearer of the shearer and the front beam of the front brake and the front beam to reinforce the front beam Roof to prevent leakage and other innovative ways to transform one by one analysis and demonstration.
