文档介绍：摘要
,共有11层可采煤层,。,。划分一个水平,上下山开采。,,煤层平均倾角15°,属于缓倾斜煤层。
本设计矿井采用双立井的开拓,集中大巷布置方式。共划分4个采区,其中首带区为111采区,布置两个工作面同时生产。开采工艺为轻型放顶煤开采,大巷采用胶带输送机运煤。年工作日为300d,采用“三八”工作制,工作面长为1600m,,班进二刀,放煤一次。
提升设备为主井采用箕斗提升,副井采用罐笼提升。
由于井田走向较长,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走向长壁采煤法开采。

Abstract
The task of this design is to construct a tons new shaft for WuGuiQiao mine has 11 minable Coal its average thickness is field of minable capacity is million tons. It can adapt for , and is divided into one levels,up and down hill mining. Average alignment in farmland in well lengthways , average slant lengthways average, rake angle in coal seam 15°, belong to the assuasive slant coal seam.
This mine shaft is applied to double vertical shaft; Layout of concentrated tunnel development method; The coalfield turns to is divided into totally 8 ming pit, thereinto the first ming pit is 111,there are two working face in this pit. Technics of this desigin is lighted discharge of top coal. This mine works 300 days every year. Adapt “three-eight” work system, the length of work face is 160 meters and the depth of coal mining machine is , and times of every team is two,discharge of toping coal once one day.
Because the coalfield lengthways is bigger, and incline of the coal seam is assuasive, and coal seam geology c. factor effects, deciding this well farmland inside plete adoption lengthways development.
Key words: WuGuiShan Coal Mine,The technology of coal mining,Lengthways development,Lighted discharge of top coal
