一、井田开采情况与发展前景白芨沟井田含煤地层为中下侏罗纪延安统,共含可采及局部可采煤层七层,截至1987年底,全井剩余地质储量22053.5万 t,可采煤量14796.3万 t,按年生产能力240万 t计算,矿井服务年限51年。该矿井于1966年开始施工,1972年局部移交投产。1981年按设计要求建成四个生产采区,并很快达到设计能力。1987年生产原煤131.4万 t,截至1987年底生产原煤1390.3万 t,其中块煤519万 t,创利润7319.51万元,税金2666.8万元,积累总额9686.31万
First, field mining situation and prospects for development Baizigou minefield coal-bearing strata in the Middle-Lower Jurassic Yan’an system, with a total of mining and mining can be partially seized seven layers, as of the end of 1987, the remaining well of 220.5355 million tons of geological reserves, Coal mining capacity of 147.963 million tons, annual production capacity of 2.4 million t calculated mine service life of 51 years. The mine started construction in 1966, partially transferred to production in 1972. In 1981, four production zones were built according to the design requirements and the design capability was soon reached. In 1987, it produced 1.134 million tons of raw coal, and produced 13.903 million tons of raw coal by the end of 1987, of which 5.19 million tons of lump coal, a profit of 73.1951 million yuan, a tax of 26.668 million yuan and a total accumulation of 96.8631 million yuan
