Coal quality characteristics and clean utilization evaluation of No.1 mine in Qiketai mining area of Xinjiang province
Based on the rich coal resources and superior geographical location of Xinjiang Qiketai mining area,the study of coal quality characteristics and its clean utilization evaluation were done,expandable ways to develop and utilize high-quality coal resources were researched.The drilling coal sample of No.1 mine field in Qiketai mining area was taken as the research object,combining with geological data,coal quality data,process properties and other pa-rameters of each coal seam,the characteristics of coal quality in each coal seam and its evolution law with geological conditions were explored.The results show that the No.1 mine field can mine 6 layers,and the buried depth of the coal seam is shallow in south,while deep in north;the organic micro components is mainly the reflectance of vit-rinite,including inert group and a small shell group;the deterioration degree is medium grade coal Ⅰ,the overall trend is low in south and high in north;each coal seam is mainly composed of low ash,high volatile content,high calorific value,medium oil yield and no adhesive long flame coal,which has the characteristics of extremely low sul-fur,low phosphorus,low chlorine,low fluorine,especially low arsenic and severe tendency of coal ash slagging.According to the evaluation system of coal clean utilization potential and the requirements of medium and low tempera-ture pyrolysis,direct liquefaction and gasification process,it can be seen that the coal clean potential of No.1 mine field is good,which can be used for gasification and medium and low temperature pyrolysis,but it is not suitable for liquefaction coal.
