摘要
矿产资源节约集约利用是影响矿山企业经济效益的一个重要因素。以阳泉市21个井工煤矿为研究对象,采用变异分析法对煤炭资源利用"三率"进行赋权,得出煤炭资源利用集约度分值,对其进行从大到小的排序并与采用聚类分析法得出的结果进行比对,确认一致后分析影响煤炭资源节约集约利用水平的影响因素。结果表明:阳泉市21个井工煤矿资源节约集约利用情况一般,其中新元和登茂通煤矿资源节约集约利用程度较好,南庄和长沟煤矿较差。煤炭资源节约集约利用主要影响因素有:(1)煤炭资源条件;(2)煤炭资源开发技术条件;(3)煤炭资源开发资金投入;(4)煤炭资源开发秩序。
Economical and intensive use of mineral resources presents an essential factor that affects mine enterprise economic beneifts. Regarding 21 underground coal mines in the city of Yangquan as study objects, this paper provides empowerment for “Three Rates” of coal resource utilization by analysis of variance. The three rates includes coal mine working section recovery rate,selected rate of raw coal, and comprehensive utilization rate of coal gangue and associated mineral resources. As a result, the scores of intensive use level of coal resources have been reached, and then ordering these sores from largest to smallest, comparing with the result obtained by cluster analysis. With the consistent results, this paper gives an analysis of the factors that affects the level of economical and intensive utilization of coal resources.It turned out that the economical and intensive utilization of resources is neither good nor bad in the 21 underground coal mines in the city of Yangquan, in which Xinyuan and Dengmaotong coal mines have been done well, while Nanzhuang and Changgou coal mines have been done badly. Finally, this paper points out the main factors that affect economical and intensive utilization of coal resources include coal resource condition,technical conditions, the funding and order for coal resource exploration.
