陕西省铜川矿务局现有生产矿井十一座,核定年生产原煤能力835万t,1988年产煤632万t。全局分为东区和焦坪矿区。东区主要开采石炭系的5号、10号煤。焦坪区主要开采侏罗系10号煤。东区煤种为贫、贫瘦、瘦煤及焦煤。焦坪区为长焰煤及不粘煤。铜川矿务局成立37年来,共生产商品煤1.5亿t,为国民经济建设做出了应有的贡献。然而,由于多方面因素的影响,全矿区均处于严重亏损状态。1987年吨煤亏损11元,1988年吨煤亏损12.3元。在矿区现有条件下,能否在煤炭产品结构上下功夫,力求增加收入,减少亏损?根据中国统配煤矿总公司的安排,我们于1988～1989年开展了铜川矿务局煤炭产品的优化工作。一、弄清矿区资源的潜在优势每个矿区都有各自的某些优势,如何将
Tongchuan Mining Bureau of Shaanxi Province, the existing mine production 11, the approved annual production capacity of 8.35 million tons of raw coal in 1988, producing 6.32 million tons of coal. The overall situation is divided into Eastern District and Jiao Ping mining area. Eastern Region, the main exploitation of the Carboniferous No. 5, No. 10 coal. Jiaoping District, the main exploitation of Jurassic No. 10 coal. Eastern coal is poor, lean, lean and coking coal. Coking area for long flame coal and non-stick coal. In the 37 years since the founding of Tongchuan Mining Bureau, a total of 150 million tons of coal products have been produced, making due contributions to the national economic construction. However, due to various factors, the whole mining area is in a serious deficit condition. In 1987 tons of coal loss 11 yuan, tons of coal in 1988 loss of 12.3 yuan. Under the existing conditions in the mining area, can we work hard on the structure of coal products and strive to increase revenue and reduce losses? According to the arrangement of China National Coal Mine Corporation, we carried out optimization of the coal products of Tongchuan Mining Bureau from 1988 to 1989 . First, to find out the potential advantages of mining resources Each mine has its own certain advantages, how to
