一、矿山概况开滦煤矿唐山矿,是一个单翼回采、多中段生产,竖井、斜井联合开拓,开采九十多年的老矿山。现有开采深度距地表达800余米。它位于开平煤田的西南翼,属石炭二迭纪煤系地层。矿区地质条件比较复杂,构造较多,倾角变化较大,有的局部地区地层倒转,奥陶纪石灰石复盖在煤层之上。地表冲积层厚达百余米不等。解放前,唐山煤矿在三座大山的压迫和反动政府的统治下,生产十分落后,工人的劳动
First, the mining profile Kailuan Coal Mine Tangshan, is a single-wing mining, multi-intermediate production, shaft, inclined shaft joint development, mining more than 90 years of old mines. The existing depth of mining more than 800 meters. It is located in the southwestern wing of Kaiping Coalfield, is a coal-bearing strata of Permian Permian. The geological conditions in the mining area are rather complicated with more tectonics and larger dip angle. Some of the strata in some areas are reversed and Ordovician limestone is covered above the coal seam. Surface alluvium thickness of more than 100 meters. Before the liberation, Tangshan Coal Mine under the domination of the oppression and reactionary government of the three mountains, the production was very backward, the labor of the workers
