1、摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为张双楼煤矿90万t新井设计,共分10章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度、设计生产能力及服务年限;4.井田开拓;5.准备。方式-采区巷道布置;6.采煤方法;7.井下运输;8.矿井提升;9.矿井通风与安全技术;10.矿井基本技术经济指标。 山脚树矿位于贵州省六盘水市盘县特区断江镇境内,交通便利。井田走向长度为4.34 km,倾斜长度5.2 km,。井田面积22.6km2,。井田内主采煤层一层,即12#煤层,平均倾角8.4,煤层平均厚3m,井田工业储量为82.72Mt,可采储量62.42Mt,矿井服务
2、年限为50.26 a。煤层硬度系数f2.3,煤质牌号为气煤、气肥煤、肥煤及1/3焦煤。本矿井为高瓦斯矿井,瓦斯相对涌出16.92m3/t。矿区综采,煤层爆炸指数30.99%36.18%,均属于有煤尘爆炸危险性煤层区内12#煤为不易自燃煤层矿井为级发火矿井,井田内的煤层自燃发火期一般为36月。矿井采用双斜井两水平开拓,采用对角式通风。一矿一面,采煤方法为长壁采煤一次采全高。煤炭运输采用钢丝绳芯胶带,辅助运输采用电机车。矿井年工作日为330 d,每天净提升时间16 h。矿井工作制度为:实行“三八”制。专题部分题目是关于煤与瓦斯突出的研究介绍 。翻译部分是一篇关于煤炭特殊开采的论文,英文原文题目为:

Its about 4.34 km on the str
6、ike and 5.2 km on the dip,with the 22.6 km2 total horizontal area. The minable coal seam of this mine is only 12 with an average thickness of 3 m and an average dip of 8.4. The proved reserves of this coal mine are 82.72 Mt and the minable reserves are 62.42 Mt, with a mine life of 50.26 a.The geolo
7、gical condition of the mine is relatively simple. The relative mine gas is 16.92m3/t.The maximum and minimum coal dust density and average is 337.8 mg/m3,136.8 mg/m3;35.2.424 mg/m3,16.2 mg/m3.The normal mine inflow is120 m3/h and the maximum mine inflow is 142 m3/h. It is bituminous coal with low mi
