| Abstract: | The Guanzhai minefield is situated at southwestern Qianxi County, Guizhou Province, its No.9 coal seam possesses identified coal resources 64.05 million tons, potential coal resources 12.78 million tons. Coal in No.9 coal seam is thin banded structured, quasi-metallic luster, splintery fracture, endogenous and exogenous fractures developed moderate grindability coal. Macrolithotypes of coal are semidull to semibright coals, microlithotype of coal is vitrinertite. Coal quality belongs to medium to high ash, extra-low volatile matter, medium to high fixed carbon and sulfur, extra-low phosphorus, medium calorific value, high stability No.3 anthracite, can be in use for power-station coal and domestic coal. |
