摘要
,共有3层设计可采煤层,。。服务年限为53a。划分两个水平开采。井田平均走向长2500m,平均倾斜长4000m,煤层平均倾角11°,属于缓倾斜煤层。
本设计矿井采用双立井的开拓方式,集中大巷布置方式。共划分12个带区,其中首带区为2个,达产工作面1个。本设计带区为东四带区,大巷装车式下部车场,综合机械化采煤。年工作日为330d,日提升时间为16h,采用“四、六”式工作制,工作面长为170m,,每日割九刀。
提升设备为主井采用箕斗提升,副井采用罐笼提升。
由于井田倾斜长度较大,且为缓倾斜煤层,以及煤层地质条件等因素影响,决定本井田内全部采用倾斜长壁采煤法开采。
由于本人知识有限,缺乏一定的现场经验。因此,本设计中难免会出现一些问题,请各位专家老师不吝指正。
关键词可采储量采煤工艺倾斜开采

Abstract
The task of this design is to construct a tons new shaft for Dayan Ming mine has three minable Coal Seam,and its average thickness is field of minable capacity is million tons. It can adapt for 53years, and is divided into two levels. Average alignment in farmland in well lengthways 2500 ms, average slant lengthways 4000ms, average rake angle in coal seam 11°, 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 12 adopt the zone mines and 1 worked faces. This worked fece is west six worked face, words 330 days every year. Adapt “thee-eight” work situation, work face is 170 meters length of circle is , and times is 4 one day.
Because the well farmland slant length is bigger, and incline the coal seam for the , and coal seam geology condition etc. factor effects, deciding this well farmland inside plete adoption slant.
Because my limit working ability and time. There must be lots of faults in this design. I plead with dirextors point them out and redify it, and I will accept it sincerely and humblely.
Key words Recoverable reserves The technology of coal mining Adoption slant
