摘　　要：有益煤矿位于贵州省盘县东北部，已查明井田内18号煤层矿产资源量1079万t。煤层结构主要为中～细条带状；金属光泽为主；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，宏观煤岩类型为半暗型，微观煤岩类型为微镜惰煤；煤质为低灰、中高硫、低挥发份、低磷、特高热值的焦煤，可作炼焦用煤和动力用煤。The youyi minefield is situated at northeastern Pan County, Guizhou Province, its No.18 coal seam possesses identified coal resources 10.79million tons. Coal seam is thin banded structured, quasi-metallic luster, mostly 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 low ash, medium sulfur, low volatile matter and phosphorus, extra-high caloric value coking coal, can be in use for coking coal and power-station coal.
