文档介绍：摘要
,共有7层可采煤层,。。服务年限为70a。划分两个水平开采。井田平均走向长5000m,平均倾斜长2000m,煤层平均倾角20°,属于缓倾斜煤层。
本设计矿井采用双立井的开拓方式,分组集中大巷布置方式。共划分12个采区,其中首采区为1个,达产工作面2个。本设计采区为西六采区,采用语大巷装车式下部车场,综合机械化采煤。矿井年工作日为330d,采用“三、八”式工作制,设计工作面长为190m,,每日割四刀。提升设备为主井采用箕斗提升,副井采用罐笼提升。
由于井田走向长度较大,且为缓倾斜煤层,以及煤层地质条件等因素影响,因此本井田内全部采用走向长壁采煤法开采。
关键词可采储量走向长壁开采立井综合机械化

Abstract
The task of this design is to construct a tons new shaft for Hegang Ming mine has three minable Coal Seam,and its average thickness field of minable capacity is . It can adapt for 70years, and is divided into two levels. Average alignment in farmland in well lengthways 5000 ms, average slant lengthways 2000ms, average rake angle in coal seam 20°, belong to the the slant the coal seam.
This mine shaft is applied to double indined shaft development method; Layout of gathing gallergand mining district eross heading; The well farmland turns to is divided into totally 9 adopt the zone mines and 2 worked faces. This worked fece is west six worked face, words 330 days every year. Adapt “thee-eight” work situation, work face is 190meters length of circle is , and times is 4 one day.
Because the well farmland lengthways length is bigger, and incline the coal seam for the , and coal seam geology condition etc. factor effects, so this well farmland inside plete adoption lengthways.
Key words Recoverable reserves Adoption lengthways Vertical prehensive mechanization
