淮北矿区含煤地层为石炭二叠系,主采煤层赋存于石盒子组的濉肖煤田有三、五煤层(宿县及临涣煤田有八、九煤层),山西组的濉肖煤田有六煤层(宿县及临涣煤田为十煤层,两组煤层法向距离60m以上。六(十)煤层结构简单,赋存稳定,适合发展综采。目前我局9个六(十)煤层生产采区,有5个上综采,3个上高档。但是,采区均为分煤层单独布置,不仅井巷工程、机电设备、通风、运输和巷修费用较高,而且不利于六(十)煤层尽快发挥效益。1989年10月,我局在海孜矿进行远距离煤层(组)集中大联
The coal-bearing strata in Huaibei Mining Area are Permo-Carboniferous strata. The main coal seams occur in the Shixiao coalfield with three or five coal seams (eight or nine coal seams in Suxian and Lintao coal fields), and the Xishao coalfield in Shanxi Six coal seams (Suxian and Lintao coalfields are ten coal seams with a normal distance of 60m or more between the two coal seams.) Six (10) coal seams have a simple structure with stable occurrence and are suitable for the development of fully mechanized coal mining. However, the mining areas are all subdivided into sub-coal seams. Not only the cost of well engineering, mechanical and electrical equipment, ventilation, transportation and alley repairs are higher, but also unfavorable to six (10 ) As soon as possible to play a benefit coal seam In October 1989, our bureau in Haizi mine long-distance coal (group) concentration of large
