1、 I 摘 要 本设计新井为大雁矿区四矿 1.2Mt/a 的新井设计， 共有 4 层设计可采煤层， 平均总厚度为 8m。设计井田的可采储量为 95.76Mt，服务年限为 57a。划分二 个水平开采。 井田平均走向长 3.26km， 平均倾斜长 5.0km， 煤层平均倾角 6.7， 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，每刀进度为 0.8m，每日割九刀。 提升设备为主井采用箕斗提升

2、，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。 关键词关键词 可采储量 采煤工艺 倾斜开采 联合开采 联合开拓 II Abstract The task of this design is to construct a 1.2million tons new shaft for Dayan of the four Administration.This mine has four minable Coal S

3、eam,and its average thickness is 8 meters.Designed field of minable capacity is95.76lion tons. It can adapt for 57ars, and is divided into one levels. Average alignment in farmland in well lengthways 3.26km average slant lengthways 5.0km average rake angle in coal seam 6.7 , belong to the the slant

4、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 0.8meters, and times is nine one day. Because the well farmland slant length is bigger, and
