采矿工程毕业设计（论文）-大雁矿业集团一矿1.50Mta新井设计[2].doc

摘要
,共有可采煤层为4层,分别为26#、27#、31#、32#, 煤层总厚度为15m。,设计服务年限为54a,由于煤层倾角为10°属缓倾斜煤层,顾本矿井设计采用小倾角煤层群开拓方式。一个水平即可达产,分13个带区。大巷运输采用10t架线式电机车牵引3t底卸式矿车运输,采用的采煤方法为倾斜长壁采煤法,采煤工艺为综合机械化采煤工艺。顶板处理方法为全部跨落法。
,矿井属低瓦斯矿井。通风方式采用抽出式。
本区含水层以煤系风化裂隙带含承压水为主,风化带以下为煤系风化裂隙含水层为辅。本区第四系地层基本无水,但却是大气降水及岩裂隙水渗入补给煤系地层含水层的良好通道。
关键词矿井设计联合开采全部跨落法

Abstract
The design of a mine as Dayan Mt / a new mine design, coal seam to four storeys 26#, 27#, 31#, 32#, seam thickness of 15 meters. Mine design recoverable reserves of Mt, design service life of 70-73, As seam inclination of 10 ° is a gently inclined seam, the LAB mine design using small angle seam group explore ways. Can reach a level of production, with 13 sub-districts. Roadway transport 10 tons of used F-Line traction motor vehicles three tons dump cars transport, The mining method for inclined longwall mining, coal mining technology for integrated mechanized mining technique. Roof approach for the entire cross-loading method. The design of the gas emission relative to m3 / t, Mine is a low-gas coal mine. Dust bombing dangerous coal, coal mine within a spontaneous tendency, ventilation is used Extraction. The District aquifer to fracture coal weathering zone containing mainly confined water weathering of coal with the following weathering fractured aquifer supplement. The fourth area is the basic formation of anhydrous, but it is atmospheric precipitation and rock fissures coal supply water to seep into the aquifer formation of a good channel.
