孔庄煤矿19r77年投产,因地质构造复杂,火成岩侵蚀严重,矿井被迫单翼开采。煤层倾角大,断层多,机械化程度难以提高,经原煤炭部核定生产能力为45万吨/年。为寻求发展,经原煤炭部批准,孔庄煤矿改扩建工程1988年全面展开,生产基建并举,在保持旱采生产不变的基础上,开始了矿井工艺的技术改造,同时增建年入洗能力105万吨选煤厂一
The Kongzhuang Coal Mine was put into production in 19r77. Due to the complex geological structure, the igneous rock was heavily eroded and the mine was forced to be single-winged. Coal seams have large dip angles, many faults, and the degree of mechanization is difficult to increase. The original coal mining department has an authorized production capacity of 450,000 tons per year. In order to seek development, approved by the former Ministry of Coal, the Kongzhuang Coal Mine Expansion Project was launched in 1988. The construction of production facilities was simultaneously carried out. On the basis of keeping the dry production unchanged, the technical transformation of the mine process was started, and the construction and renovation of the mine were added. Capacity of 1.05 million tons of coal preparation plant
