摘要
,总共有3层可采煤层,它们分别为33#、35#、38#, m,煤层工业牌号为1/3焦煤。井田走向长度平均为5839 m,倾向长度平均为2876 m,煤层平均倾角为19°,,。
本设计矿井采用双立井的开拓方式,划分为2个水平,18个采区。两个工作面达产,达产时采区个数为两个。33#层单独开采,35#、38#层集中开采。大巷运输采用10t架线式电机车牵引3t底卸式矿车运输,采用的采煤方法为走向长壁采煤法,采煤工艺为高档普采采煤工艺。顶板处理方法为全部垮落法。年工作日为330天,采用“四—六”式工作制,工作面长为190m,,每日割6刀。提升设备为主井采用箕斗提升,副井采用罐笼提升。
关键词: 矿井设计集中大巷走向长壁采煤法
Abstract
This design is Mt / a new mine design of the Jixi Mining Group Pinggang mine. There are three layers that can adopt the coal seam. They are the 33#, 35#, 38#. Total coal thickness is m. Coal industry brands is 1 / 3 average strike length of the mine is 5,839 m. The average tendency length of the mine is 5,839 m. The average inclination of the mine is 19 °. Recoverable reserves of the mine design is Mt. Design service life is .
The design of mine pioneering ways is double-shaft. It is divided into two levels and 18 mining area. Two work faces reaches to the produce,and mining area of reaching to the produce is two .33# layer is adopted # layer and 38# layer are adopted together. The big lane conveyance adopts 10 t a line type electrical engineering cars that leads 3 t bottom unload type mineral cars. Mining method is longwall mining method . Mining technology is high-grade general mining coal technology. Roof approach is the entire cross-loading method. Working days is 330 days every year. Work system us "four-six" work system. The length of working face is 190 m. Each knife progress is m,and there are 6 times one main well adopts Ji Dou promote,and vice-well adopts bottle of the cage promote.
Key words:Mine design Concentrate big lane Longwall mining method
