摘 要 设计矿井为红旗煤矿1.2Mt/a新井设计,共有2层可采煤层,平均总厚度为5.3m。设计井田的可采储量为8701.5万t,服务年限为51.7a。划分一个水平开采。井田走向长5.037km,倾斜长3.165km,煤层平均倾角3°,属于缓倾斜煤层。 本设计矿井采用双斜井的开拓,大巷条带布置方式。共划分54个带区,其中首采区为9101采区,只布置一个工作面生产。开采工艺为综合机械化采煤,大巷采用胶带输送机运煤。年工作日为330d,采用“三八”工作制,工作面长为290m,截深0.6m。 提升设备为主井采用皮带提升,副井采用串车提升。 由于井田为缓倾斜煤层,以及煤层地质条件等因素影响,决定本井田采用倾斜长壁采煤法开采。 关键词:红旗煤矿,采煤工艺,倾斜长壁 Abstract The task of this design is to construct a 1.2million tons new shaft for Red flag Administration.This mine has 2 minable Coal Seam.and its average thickness is 5.3 meters.Designed field of minable capacity is 8.0715 million tons. It can adapt for 51.7years, and is divided into one levels mining. Average alignment in farmland in well lengthways 5.037km, average slant lengthways 3.165km average, rake angle in coal seam 3°, belong to the assuasive slant coal seam. This mine shaft is applied to double inclined shaft; Layout of concentrated tunnel development method; The coalfield turns to is divided into totally 54 ming pit, thereinto the first ming pit is 9101,there are only one working face in this pit. Technics of this desigin is geological condition of coal . This mine works 330 days every year. Adapt “three-eight” work system, the length of work face is 290 meters and the depth of coal mining machine is 0.6meters. Because the coalfield lengthways is bigger, and incline of the coal seam is assuasive, and coal seam geology conditionetc. factor effects, deciding this well farmland inside the complete adoption lengthways development.
