摘要(Abstract):

通过对乌达矿区主采煤层中主要矿物黄铁矿、粘土矿物和有机硫的赋存状态分析 ,认为在现有的技术和经济条件下 ,对单个煤层的降硫脱灰是不切实际的 ,只有综合考虑矿区所有的主采煤层 ,合理布置采区 ,针对不同的煤层 ,选择合适的配比进行煤的洗选 ,实现地质 -采矿 -选矿的有机融合、动态协调是目前提高煤炭质量的最佳途径
According to the analysis of occurrences of pyrite, clay mineral and organic sulfur in the main mined coal seam in Wuda coalfield, it can be seen that it is not practical to decrease the content of sulfur and ash in a single coal seam at present technical and economic condition. The best way to increase the coal quality is to lay the mining area reasonably, choose the ratio of the different coal seam appropriately, and realize the harmony of the geology, mining, and coal washing.
