发展煤矿综合加工利用,是煤炭企业的必然选择。据1986年统计,成本和资金利润率,电力为55.4%和16%,石油为106.3%和63.5%,而煤炭却为-109%和-55%,利润全为负值。以四川省为例,每生产1吨煤就平均亏损25元。而对四川煤炭系统综合加工利用的技术经济论证,资金利润率一般为10%～15%。笔者试结合芙蓉矿务局近年来利用矿区资源优势,发展综合加工利用的实际,谈谈其经济和社会价值。——化害为利,发展瓦斯利用效益工程。
The development of comprehensive utilization of coal mines, coal enterprises is the inevitable choice. According to the statistics, cost and capital profit margin of 1986, electricity was 55.4% and 16%, oil was 106.3% and 63.5%, while coal was -109% and -55%, all of which were negative in profit. In Sichuan Province, for example, every ton of coal produced on the average loss of 25 yuan. The technical and economic feasibility study on the comprehensive processing and utilization of the coal system in Sichuan shows that the profit rate of capital is generally 10% to 15%. The author tries to combine Furong Mining Bureau in recent years the use of mining resources, the development of integrated processing and utilization of the actual, talk about its economic and social value. - harm for the benefit of the development of gas utilization efficiency project.
