摘要
,共有7层可采煤层,井田平均走向长2000m,平均倾斜长3500m,煤层平均倾角17°,属缓倾斜煤层。。煤层工业牌号以1、2号肥煤为主,局部气肥。 Mt,服务年限为65年,本矿井设计采用双立井方案开拓,划分两个水平,一个工作面达产。采用集中大巷布置,大巷采用8吨蓄电池电机车牵引3吨底卸式矿车运输,采煤方法为倾斜长壁采煤法,采煤工艺为综合机械化采煤工艺。
关键词:水平开拓带区集中大巷
Abstract
This design is the Qi tai he jing mei industry group pany of a new well design, having totally 7 layers can adopt the coal seam, The well field moves towards long 4200m equally, medium bank long 3500m, the coal bed average inclination angle 17°, is the easy gradient coal bed.
average thickness seam industry card number is 1 and 2 fatty coals in numbers are lords, the partial spirit is the well farmland can adopt to keep the Mts of deal, the service time limit is 65 years, this mineral well design adoption a well project expands, dividing the line two levels, a work reaches to big lane in concentration in adoption arranges, the big lane adopts 8 ton storage battery electrical engineering cars lead 3 ton bottom unload type mineral cars transport, adopting coal method as to tilt to one side the long wall adopt the coal method, adopting coal craft as to synthesize the mechanization adopt the coal craft.
Key words:Level Expand Adopt the area Concentrate big lane
