一般说来,采面高产高效低耗与煤层赋存条件、采面布置(单一或对拉采面)、参数大小、机械化程度和采面推进度等因素有关。现以开滦唐山矿南翼五煤层七个综机采面为例,在如图—1所示的煤层赋存条件基本一致,采用统一的每柱70—100吨的节式组合迈步支架和170型双滚筒采煤机综机设备,回采工艺和劳动组织基本相同的条件下,从月产、工效、坑耗与面长、推进度及对拉工作面的关系,
Generally speaking, the high production, high efficiency and low consumption of coal face are related to the conditions of coal seams, the layout of mining face (single or double face), the parameter size, the degree of mechanization and the propulsion level of coal face. Taking the coal face of the seven fully mechanized coal faces of the fifth coal seam in the south wing of the Tangshan Mine in Kailuan for example, the conditions for occurrence of the coal seams shown in Figure 1 are basically the same. A unified column-type combined stepping bracket of 70-100 tons per column 170 double drum shearer under the conditions of the same basic equipment, mining technology and labor organization, from the monthly production, ergonomics, pit consumption and the surface length, the degree of propulsion and the relationship between the pull surface,
