近年来,随着矿井采掘机械化程度的提高和采掘部署的拓展,矿井已大量开采6号煤层,此煤层厚度薄、灰分高,煤质变化大,矸石泥化程度严重,加之与7号、8号层煤在井下掺配比例不当,进入煤仓、转运,有时甚至不经掺配直接进入洗选厂入洗,致使入厂原煤的煤质波动大,工艺流程、参数调节频繁。大量的铝土矿物、页岩等离子进入煤泥水系
In recent years, with the improvement of mine excavation mechanization degree and the expansion of mining deployment, the mine has largely exploited No.6 coal seam, which has thin thickness, high ash content, large changes of coal quality and serious muddy degree of gangue. Coupled with No. 7, 8 No. Coal layer in the underground mixing with improper ratio, into the coal warehouse, transport, and sometimes even without directly into the washing plant into the washing, resulting in coal into the coal plant fluctuations, process, adjust the parameters frequently. A large number of bauxite, shale plasma into the slime water system
