摘要
,共有4层设计可采煤层,平均总厚度为8m。。服务年限为61a。划分一个水平开采。井田平均走向长4700m,平均倾斜长2724m,煤层平均倾角9°,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11个带区,其中首带区为二个,达产工作面一个。本设计带区为西一,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190m,,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。
关键词水平采煤工艺倾斜开采
Abstract
The task of this design is to construct a tons new shaft for Dayan of the first Ming mine has four minable Coal Seam,and its average thickness is 8 meters. Designed field of minable capacity is million tons. It can adapt for 61years, and is divided into one levels. Average alignment in farmland in well lengthways 4700 ms, average slant lengthways 2724ms, average rake angle in coal seam 9°, belong to 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 11adopt the synthesis mechanization mining coal and two worked faces. This worked face is west one worked face, words 330 days every year. Adapt “four-six” work situation, work face is 190 meters 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.
Key words Level The technology of coal mining Adoption slant
