碱沟山矿区煤层赋存条件、成煤环境、聚煤规律及煤质特征研究程度较低。经对煤层露头及小窑资料的研究,认为该矿区含煤地层为上石炭系羊虎沟组下段,主要开采10、12、14、15、16号煤层,12和15号煤层原煤灰分、硫分稍高,10、14和16号煤层为特低灰、特低硫至富硫煤层;该区煤为高发热量,特低磷—低磷煤。煤的加工利用途径主要为作碳素类制品、石墨类制品、高炉喷吹的原料(冶金喷)以及作烧结铁矿的原料等;也可进行深加工及转化加工。
The occurrence conditions, coal-forming environment, coal-accumulating law and coal quality in the alkali hill seam mining area are less studied. Based on the study of coal outcrop and small kiln data, it is considered that the coal-bearing strata in the coal mines are the lower part of the upper Carboniferous Yanghugou Formation, mainly producing coal seam No.10, No.12, No.14 and No.16 and No.12 and No.15 coal ash, sulfur As a result, the coal seams Nos. 10, 14 and 16 are ultra-low ash and extra-low sulfur to sulfur-rich coal seam. The coal in this area is high in calorific value, ultra-low phosphorus and low-phosphorus coal. Coal processing and utilization of the main ways for the carbon products, graphite products, blast furnace injection of raw materials (metallurgical spray) and sinter for iron ore raw materials; can also be deep processing and conversion processing.
