摘要
任家庄煤矿位于宁东横城矿区,主要含煤地层为太原组和山西组.在对以往勘探煤质资料进行统计的基础上,系统分析了主要可采三、五、六、九号煤层的水分、硫分、灰分等煤质特征及分布规律,并进行了煤炭洁净程度和气化特征划分.研究表明:三号煤层属较好—中等洁净煤,气化用煤类型主要为水煤浆、干煤粉气化用煤;五号煤层属较好—中等洁净煤,洗选加工后,可作为焦化用煤利用;六号煤层属好—较好洁净煤,洗选加工后,可作为焦化用煤利用;九号煤层属较好—中等洁净煤,气化用煤类型主要为水煤浆、干煤粉气化用煤.
Abstract
Renjiazhuang Coal Mine is located in the Hengcheng mining area,east of Ningxia Coal Field.The main coal-bearing strata are Taiyuan Formation and Shanxi Formation.In this study,the characteristics and distribution of coal composition,such as total moisture,sulfur content and ash content in No.3,5,6 and 9 coal seams are systematically analyzed by the method of statistics,and the degree of coal cleanliness and gasification characteristics are divided.The research shows that No.3 coal seam is good-medium clean coal,and the coal mainly used for gasification of coal water slurry and dry coal powder.No.5 coal seam is good-medium clean coal and mainly used for coking coal for utilization After washing and processing.No.6 coal seam is excellent-good clean coal and mainly used for coking coal for utilization After washing and processing.No.9 coal seam is good-medium clean coal and mainly used for gasification of coal water slurry and dry coal powder.
