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。一般部分为司马煤矿2.4 Mt/a新井设计。司马煤矿位于长治县境内,行政区划隶属长治县苏店镇,北距长治市14km,交通便利。井田范围近一六边形,长宽各约6km,总面积29.494km2。井田内主采煤层为一层,为3#煤。煤层倾角平均3,平均厚度6.8 m。井田地质条件较为简单。矿井工业储量为26897.94万t,可采储量为21832.74万t。矿井设计生产能力为2.4Mt/a。矿井服务年限60.6 a。矿井涌水量不大,正常涌水量为111m3/h,最大涌水量为201m3/h。矿井相对瓦斯涌出量为0.67m3/t,属低瓦斯矿井。矿井煤尘具有爆炸
2、危险性,但煤层不易自燃。矿井采用立井单水平开拓。一矿一面,采煤方法为综合机械化放顶煤开采。全矿采用胶带运输机运煤,辅助运输采用矿车。矿井通风方式前期为中央并列式。 矿井年工作日为330 d,日净提升时间16h,工作制度为“三八制”。专题部分题目是煤矿粉尘防治技术研究。在煤矿开采中,掘进、回采、运输各环节中都会产生大量粉尘,粉尘不仅会危害井下职工的身体健康,还可能导致煤尘爆炸等恶性事件。目前国内外粉尘的防治技术主要在减尘、降尘、排尘、隔尘、捕尘、个体防护六个方面展开研究。翻译部分主要内容为关于煤矿火灾模型,英文题目为:Recent Developments and Practices to Co
