摘要
,共有4层设计可采煤层,,煤的工业片牌号为1/3焦煤。,服务年限为63a,全矿井划分为二个水平开采。煤层平均倾角
15°,井田平均走向长4900m,平均倾向长4000m。
本设计矿井开拓方式为双立井开拓,集中大巷方式。共划分4个采区,其中首采区为1个,投产工作面1个,。本设计采区为东一采区,大巷装车式下部车场,采煤工艺为综合机械化采煤。年工作日为330天,采用“三、八”式工作制,工作面长为180m,,每日割七刀。
提升设备为主井采用箕斗提升,副井采用罐笼提升。

Abstract
The task of this design is to construct a million tons cheng zi he for Jixi Ming mine has four minable Coal Seam, and its average thickness is meters, types of coal seam is 1/3 coking coal. Designed field of minable capacity is million tons. It can adapt for 63years, and is divided into two level.
This mine shaft is applied to double indined shaft development method; Layout of gathing gallergand mining district eross heading; This level is divided into 4 mining districts and 1 worked faces. Time of constructing shaft is months. This worked fece is middle 1 worked face, ords 330das every year. Adapt “three-eight” work situation, work face is 180 meters length of circle is meters, and times is7one day.
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.
