摘要
新店西二勘查区位于贵州省清镇市北部,全区大部分可采煤层为9号煤层;经过对煤质资料的整理与分析表明,煤以粉粒状为主块状、碎块状次之;煤层结构主要为线理―细条带状;似金属光泽为主;断口主要为参差状,少量平坦状或贝壳状;内生裂隙较发育,充填细脉状方解石;宏观煤岩类型为半暗―半亮型;微观煤岩类型为微镜惰煤;煤质为中灰、中高硫、特低挥发分、低磷、高发热的无烟煤。
Xindian West II exploration area is located at north part of Qingzhen of Guizhou,and most of the minable seam in this area can be categorized as No.9 coal seam.According to the analysis on coal quality da-ta,the coal is mainly in the form of particle and partially in massive or lumpy form.The coal seam is prima-rily in the form of lineation-thin banded structure.The coal has metalloid luster and there are many uneven fractures with a small amount of plane fractures and shell like fractures.Cleating is well developed and is filled with fine grained calcite.The macroscopic lithotype of coal is semidull-semibright,while the micro-scopic lithotype of coal is vitrinertite.The coal is anthracite which is characterized by medium ash,medium-high sulphur,ultra-low volatile matter,low phosphorus and high calorific value,and it can be used as do-mestic coal and power coal.
