1、 II 摘要 本设计通过详细介绍城郊 2 矿的井田概况和施工方法,经过一系列的方案论证比 较, 选择了适合本矿井的开拓方式、 施工方法和各生产系统。 井田内地质构造比较简单, 主要为纵贯井田南北的 F5、F17断层,属于低瓦斯矿井,无煤尘爆炸危险;本井田主要有 三层可采煤层,按埋藏深度从浅到深分别为三4、三2、三1煤层,煤层倾角 19 o25o, 平均 23 o。经过技术经济比较,煤矿设计生产能力为 60 万 t/a,服务年限为 48 年,采 用立井开拓方案。本设计包括拟扩建矿建概况,施工准备,立井施工,井底车场及硐室 施工以及大巷施工等内容。对于安全方面,本矿井为低瓦斯矿井,但为确保安全特设
2、置 瓦斯监控系统。 总之,通过技术经济等多方面的比较得出本设计的开拓方案、施工方法等均能满足 矿井施工要求。 关键词:关键词:立井开拓;冻结法;光面爆破;立井开拓;冻结法;光面爆破;综合机械化配套、短段掘砌混合作业方式综合机械化配套、短段掘砌混合作业方式;中;中 央分列式通风央分列式通风 Abstract This design through the detailed introduction of suburban 2 ore field survey and construction method, through a series of solutions, choose a suit
3、able demonstration of the mine exploitation and construction method and the production system. Within the field of geological structure is simple, mainly through the field for F17 faults, belong to the F5 and low gas mine, no coal-dust explosion danger; The three main field by coal, from shallow to
4、deep buried depth respectively, three 2, April 3, the thickness of the coal seam an average of 3:1 m, 1.46 respectively, 1.16 m j, 1.16, coal 19o Angle, average 25o 23o. After technical and economic comparison, coal production capacity of 60 million t/a, service for 48, using vertical development plan. Anyhow, through comparison of technical and economic aspects of the design of that plan, construction methods etc all can meet demands mine construction. III Keywords: vertical pioneering, Fr
