Coal Quality Characteristics and Industrial Application Evaluation of Shajingzi Central Part Coal Mine in Huan County of Gansu Province
摘要
Abstract
Taking the Shajingzi Central Part Coal Mine in Huan County of Gansu Province as the research object,the coal rock and coal quality characteristics of each minable coal seam,as well as the content characteristics of harmful elements in coal,are analyzed.The process performance of the main minable coal seams in the area is systematically analyzed,and its industrial utilization direction is objectively evaluated.The research results indicate that each minable coal seam in Shajingzi Central Part Coal Mine in Huan County belongs to the long flame coal type,and the macroscopic coal rock type of each minable coal seam is dark to dull briquette,with clamp bright coal bands and a small amount of mirror coal lineation and silk charcoal thin strips or lens bodies.It has the characteristics of ultra-low～low moisture,low ash～medium ash,low medium sulfur,low chlorine,geothermal stability,etc.The various indicators of minable coal seams meet the requirements of power generation coal and meet the requirements of four types of gasification processes,suitable utilization directions include coal for power generation,coal for gasification,coal for chemical industry,heating,kilns,and civilian fuels.关键词
