摘要
,井田有可采煤层5层,即47#、48#、49#、51#、58#煤层,,均属于中厚煤层,煤层工业牌号为1/3焦煤。,, Km2。,。
该设计矿井采用双立井开拓方式,根据井田垂深可划分三个开采水平。采用集中大巷布置,。采煤方法为走向长壁采煤法,采煤工艺为普通机械化采煤工艺,采空区处理采用为全部垮落法。
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。
矿井的通风方式为两翼对角抽出式。
关键词:开拓;水平;集中;走向长壁
Abstract
This is a new design gor of Xinxing in Qitaihe coal mining has five workable coal seams,they are 47#,48#,49#,51#,58# ,total thickness of coal seam is coal seam industry trademark is 1/3 coking mne is long and width,the mine area is mie field recoverable resources is mine’s life is 59 years.
This mine pit design uses take the double vertical shaft development,the division as there levels,Uses concentrates the big lane big ransportation uses 10 ton wire laying type electric otive to tow the 3 ton Bottom-dump mine cars to transport,uses long wall mining on the strike to wining technology is the ordinary mechanized coal wining wse the caving method for all working faces.
The main well uses the multi-ropes to rub the ore basket promotion, the vice-well uses the bination pot cage promotion.
The well ventilated way of mineral well is for two wing opposite angles draw out types.
Keyword: development; level; concentrate; long wall on strike
