摘　　要：竞发煤矿位于贵州省晴隆县，已查明井田内22号煤层矿产资源量1152万t。煤层结构主要为中～细条带状，少量宽条带状和线理状；金属光泽为主，少量似金属光泽、金刚光泽；断口主要为参差状、平坦状，少量贝壳状、阶梯状；内生裂隙较发育，偶见少量外生裂隙，充填薄膜状、网格状、脉状方解石，含较多结核状、透镜状、浸染状、星散状、团块状黄铁矿，宏观煤岩类型为半暗型，微观煤岩类型为微镜惰煤；煤质为中灰、中高硫、特低挥发份、高热值的无烟煤，可作动力煤、民用煤和火力发电。The JingFa minefield is situated at QingLoug County of Guizhou Province. It＇ s No.22 coal seam possesses identified coal resources 11.52 million tons. Coal seam is mostly threadthin banded structured, quasimetallic luster, splintery and flatness fracture, few conchoid and ladder fracture, endogenous fractures developed, little exogenous fractures. Macrolithotypes of coal is semibright coal, microlithotypes of coal is vitrinertite. Coal quality belongs to medium high ash, high sulfur, low volatile matter and phosphorus, moderate heat of hydration lean coal, can be used for civill and powerstation coal.
