摘要
,井田共有可采煤层五层,分别为58#、59#、62C#、63#、65B#煤层,。本区煤层煤种有焦煤、肥煤、1/3焦煤并有少量瘦煤、贫煤、无烟煤,其中以焦煤为主,,设计服务年限为57a。
设计采用双立井开拓方式,集中大巷及采区石门的大巷布置方式。。本井田共划分12个采区,58#、59#联合开采,62C#、63#、65B#单层开采,投产工作面1个。本设计采区为中一采区,采用石门装车式下部车场,分区式通风,工作面年工作日为330d,采用“四、六”工作制,工作面长为120m,,采用的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,顶板处理方法为全部垮落法。

Abstract
This is a pit design of Long Hu coal mine of Qi Taihe,The ability production of the mine coal is new design has five coverable coal seams,they are 58#,59#,62C#,63#,65B#,the total thickness of the seam is meters. Coal industry brands for 1/3 coke, The recoverable reserves is and the service life is 57a.
The mine take double vertical shaft development, concentrated in large mining area roadway and the Shihmen the roadway bottom of the roadway transport planes take 10 tons car and tons mine mine field is divided into 16 mining area to explore, a mixed layout, 62C #, 63#, 65B# slice mining, 58#, 59# joint exploitation of each mining area for single-wing exploitation, face an operation. The design mining area for a mining area, using the lower part of the Shihmen-loading garage,area ventilation,Working face 330 days, adopt "four to six" working system,The length of the woking face is 120 metres,the progress of cycle is metres,The working face takes longwall working Technology is ordinary mechanized mining technology.
