摘　　要：银星一号煤矿位于宁东煤田积家井矿区北部,区内煤炭资源丰富,煤质优越,是宁夏境内最重要的煤炭生产基地之一。通过对银星一号煤矿含煤地层特征、煤的物理性质、煤岩特征、化学性质和工业性能的分析,探讨了煤层煤质特征,并对其工业用途进行了评价。研究表明,银星一号煤矿煤层主要赋存于中侏罗统延安组第一、第二含煤岩段,共含编号煤层22层,其中可采煤层9层,可采含煤系数为4.85%。各可采煤层煤类主要为不粘煤,颜色以黑色为主,弱沥青光泽,参差状、贝壳状断口,宏观煤岩组分以暗煤为主,属特低灰—低灰、中高挥发分、特低硫—低硫、中等固定碳和高发热量煤。煤层粘结性能差、强度高、较难—中等可磨、中等—中高热稳定性。煤的用途广泛,主要可用于动力用煤和煤化工用煤。Yinxing No.1 Mine is located in the northern part of Jijiajing mining area of Ningdong coalfield,which is rich in coal resources and has superior coal quality.By analyzing the characteristics of coal-bearing strata,physical properties of coal,coal rock characteristics,chemical properties and industrial properties of Yinxing No.1 Mine,the coal quality characteristics of coal seams were explored and their industrial uses were evaluated.The study showed that the coal seams of Yinxing No.1 Mine were mainly located in the first and second coal-bearing rock sections of the Middle Jurassic Yan'an Group,containing a total of 22 numbered coal seams,including 9 recoverable coal seams,with a recoverable coal-bearing factor of 4.85%.The coal type of each recoverable coal seam was mainly non-stick coal with black color,weak asphalt luster,jagged and shell-like fracture,and the macroscopic coal rock components were mainly dark coal,which was extra low ash-low ash,medium-high volatile matter,extra low sulfur-low sulfur,medium fixed carbon and high heat generation coal.The coal seam was poorly bonded,high strength,harder-medium grindable,and medium high thermal stability.The coal can be used for a wide range of applications,mainly for power coals and coal chemical coals.
