摘要
,煤层工业牌号为肥气煤,共有4层可采煤层,,。 t,。
该设计矿井采用双立井开拓方式,划分二个开采水平。煤层平均倾角12°,属于缓倾斜煤层。采用分组集中大巷布置,大巷采用架线式电机车牵引底卸式矿车运输,采煤方法为倾斜长壁采煤法,采煤工艺为综合机械化采煤开采,采空区处理方法为全部垮落法。
矿井的通风方式为对角抽出式。
主井采用多绳摩擦箕斗提升,副井采用刚性组合罐道罐笼提升。
关键词分组集中倾斜长壁开拓方式采煤工艺
Abstract
This design mineral well as the jixi mineral industry group limited pany almond flower coal mine a new well designs, having totally four layers can adopt the coal seam, average and total thickness is metre, average and total thickness is coal seam industry card number is a fatty spirit coal, designing the well farmland can adopt to keep the Mts of deal, the service time limit is years.
This mineral well design adoption a upright well expands the way, dividing the line two mine the level. average rake angle in coal seam 12°, belong to the the slant the coal cent the set concentrates the big lane arranges, the big lane adopts a lectrical engineering car leads a bottom unload type mineral car transports, adopting coal method as the alignment long the wall adopts the coal method, adopting coal craft as to synthesize the mechanization adopt the coal craft, adopting empty the area handles method as all falls the method. Well ventilated way that mineral well as the central being juxtaposed the draw out type
The main well adoption many rope rub the box promotes, the vice- well adopts the bination a cage promotes.
key words:the cent the set concentrates expands the level
alignment long wall
