顿巴斯中心区域急倾斜极薄煤层,由于工作面空间对人还是机械的作业都有限制,加之采矿工程的延深,使复杂的地层赋存矿山地质条件(煤或者瓦斯突出的危险性)进一步恶化,给机械化开采带来一定困难。 厚度0.3—0.7米急倾斜煤层机械化采煤装置的研制是采煤机械化领域最重要的任务之一。战后许多科研设计部门进行了多次尝 Extremely steeply inclined coal seam in the center of Donbass, there are limits to man or machine operation due to the space in the working face. In addition, the deepening of the mining engineering causes the complex stratum to occupy the mine geological conditions (danger of coal or gas outburst) Further deterioration, to mechanized mining brought some difficulties. Thickness of 0.3-0.7 m steep coal seam mechanized mining device development is one of the most important tasks in the field of coal mining mechanization. Many research and design departments conducted many attempts after the war
