1、摘 要本设计包括两个部分:一般设计部分和翻译部分。一般部分为祥荣煤矿0.6M万/t新井设计,煤矿位于陕西省府谷县新民镇,南与陇海线相接,北与京包线相连,向东有大秦、神黄两条西煤东运线通道与京九、京广线相接认定拢,形成了四周与全国运输网络的相互衔接,井田东西走向平均2.3 km,南北倾向平均3.2 km,井田水平面积约为6.25 km2。主采煤层一层,5号煤层,平均厚度4米,平均倾角8.9。井田工业储量3540万t,可采储量3185万t,矿井服务年限41a。矿井地质条件简单,煤层埋深平均50米,属于低瓦斯矿井,每层有自然发货的倾向,煤层具有爆炸的危险性。根据井田的地质条件,井田采用盘区布置条带式
2、开采,分为上下两个盘区,两个水平开采。采用一次性采全高采煤方式,全部垮落法处理采空区。矿井采用“三八“制作业,两班生产,一班检修。生产班每班两个循环,日进四个循环,循环进尺0.8m。大巷采用带式输送机运煤,辅助运输采用无轨胶轮车。主井装备一条胶带运输。矿井采用抽出式通风。矿井通风容易。矿井通风困难时期矿井总风量4608 m3/min,矿井通风总阻力2746 Pa,风阻0.46 Ns2/m8,等积孔1.74 m2,矿井通风中等困难。关键词:斜井;盘区开采;大采高;单巷掘进;抽出式AbstractThe design includes two parts:generaldesign part an
