厚夹矸煤层分层综采与合层综放经济效益对比分析

Analysis on Economic Benefit Comparison between Fully Mechanized Mining in Slice of Thick Seam with Thick Partings and Fully Mechanized Top Coal Caving Mining in Seams Combined

以淮北芦岭煤矿8#、9#为研究对象,以技术经济为基础,基于采煤直接成本与洗选成本的综合成本,对比分析了分层开采与合层综放开采之间的差异,同时考虑到开采效率不同的资金动态效益,得出了合层综放开采具有综合效益的优势,指出合层综放可作为芦岭矿合适区段的首选工艺。

Taking No. 8 and No. 9 seams in Luling Mine of Huaibei as a study object and the technology and economy as the base, base on the comprehensive cost of the coal mining direct cost and the coal preparation cost, the difference between the slice mining and the fully mechanized top coal caving mining in seams combined was compared and analyzed. Meanwhile in consideration on the funds dynamic benefits of the mining efficiency different, the fully mechanized top coal caving mining in seams combined would have the advantages of the comprehensive benefit. The paper pointed out that the fully mechanized top coal caving mining in seams combined could be the first selected mining technique in the suitable section of Luling Mine.
