摘要
新街井田位于贵州省清镇市北西部,已查明井田内9号煤层矿产资源量6405×104t,潜在矿产资源量1278×104t;9号煤为细条带状结构,玻璃、弱玻璃光泽,贝壳状、参差状断口,内、外生裂隙较发育,属中等可磨煤;宏观煤岩类型为半暗-半亮型,显微煤岩类型为微镜惰煤;煤质为低中灰、中硫、高热值、低挥发分、低磷、极易可磨、特低氯,煤类划分均属无烟煤三号。可作民用煤、工业动力用煤和火力发电用煤。
The Xinjie minefield is situated at northwest of Qinzheng city of Guizhou Province. The No. 9 coal seam of it possesses identified coal resources 64. 05 million tons, potential coal resources 12. 78 million tons. Coal in No. 9 coal seam hasstriped structure, quasi-glass luster, conchoids and splintery fracture, endogenous and exogenous fractures developed, is moderate grind-able coal. Macroscopically coal type is semi-dark to semi-bright coal. Micro coal type is inert coal. Coal quality belongs to low to medium ash, medium sulfur, high calorific value, low volatile matter, low phosphorus, easy grind-able, extralow chlorine, coal type belong to anthracite No. 3. It can be in use for power-station coal and domestic coal.
