莆浪煤矿可采煤层煤质特征浅析

The workable coal seam characteristics analysis of Pulang coal mine

介绍了莆浪煤矿区内主要可采煤层的煤类、煤质特征及煤的工艺性能,并对其矿井资源量进行估算。矿区内煤类为无烟煤,构造复杂程度中等,可采煤层为较稳定型。矿区最低可采厚度0.80m。主要可采煤层煤均属中灰、特低挥发分及高硫分煤,其最低发热量(Q_(gr,d))为22.1 MJ/kg,筛分洗选后可配合用作电力用煤、化工用煤。

Based on the coal occurrence circumstances in the minable seam of Pulang coal mine,the coal types,coal quality features and process performance in the mining area were introduced,and the resources of the mine were estimated.The coal in the mining area is anthracite with moderate structural complexity,and the minable seam are relatively stable.Lowest mine mining thickness is 0.80 m.The coal from main workable seam coal belongs to medium ash,extraordinarily low volatile matter and high sulfur coal,the lowest dry basis high calorific value was 22.1 MJ/kg,after screening and washing,the coal could be used as power coal,chemical coal.
