西德长壁工作面的采深为400～1400米,几层煤层的地质条件大致相似。目前开采的多数为缓倾斜和倾斜煤层,厚度在0.8～4.0米,层间距往往只有几米。据1980年提供的平均数,工作面采向长度947米,工作面长226米,煤层厚1.54米,工作面商品煤日产量1408吨,原煤含矸率47％。虽然地质构造复杂,但综采工作面的产量比重已达96％,
West Germany longwall face mining depth of 400 to 1400 meters, several layers of coal seam geological conditions are generally similar. The majority of the current exploitation of gently inclined and inclined seam, the thickness of 0.8 to 4.0 meters, the interval is often only a few meters. According to the average provided in 1980, the working face has a length of 947 meters, a working face of 226 meters long, a coal seam of 1.54 meters, a daily production of commercial coal of 1,408 tons and a content of 47% of raw coal. Although the geological structure is complex, but the proportion of fully mechanized mining face has reached 96%
