宁东红柳井田煤质特性分析及综合利用

Coal quality characters analysis and coal comprehensive utilization of Hongliu shaft area in Ningdong

在前期设计阶段对宁东红柳井田的煤炭资源赋存条件及不同煤层煤样进行分析预测,并根据实际掘进煤层的煤质情况讨论井田的煤质变化及综合利用途径。分析研究表明,红柳井田构造中等,煤层赋存稳定,主要可采煤层厚度较大,煤炭储量丰富,可采煤层的煤质优良,其为低水分、低灰、中低硫、中高挥发分、高热值的不黏煤,适宜作为燃料动力及化工原料用煤。

In preliminary design phase,the occurrence condition of coal resources and coal sample from different coal seams of Hongliu shaft area in Ningdong were analyzed and predicted,and according to coal quality characteristics of actual driving seam,the coal quality changes and comprehensive utilization methods were discussed.The research shows that,Hongliu shaft area structure is medium,the occurrence of coal seam is stable,the main workable seam is relatively thick,the coal reserves are rich,the coal quality of workable seam is good,the coal is the low-moisture content,low ash,medium-low sulfur,mediumhigh volatile matter and high calorific value non caking coal,taking it as coal for fuels and energy or for chemical raw materials will be suitable.
