文档介绍：摘要
,共有4层设计可采煤层,平均总厚度为8m。,服务年限为57a。划分二个水平开采。,,°,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8个带区,其中首带区为二个,达产工作面一个。本设计带区为东一带区,大巷装车式下部车场,综合机械化采煤。年工作日为330d,采用“四、六”式工作制,工作面长为200m,,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。

Abstract
The task of this design is to construct a tons new shaft for Dayan of the four mine has four minable Coal Seam,and its average thickness is 8 field of minable capacity tons. It can adapt for 57ars, and is divided into one levels. Average alignment in farmland in well lengthways average slant lengthways average rake angle in coal seam °, 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 8 adopt the synthesis mechanization mining coal and one worked faces. This worked face is east worked face, words 330 days every year. Adapt “four-six” work situation, work face is 200ters length of circle is , and times is nine one day.
Because the well farmland slant length is bigger, and incline the coal seam for the , and coal seam geology c. 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 Unites to mine Unites to expand
