安居煤矿年产150万吨新井设计说明书-本科毕业论文.docVIP

摘要 本设计包括两个部分：设计部分和专题部分。 设计部分为万t/a新井设计位于山东省济宁市市中区内兖以南，京杭运河以西专题题目为深井护巷技术探讨 关键词：矿井初步设计 开拓设计采区设计 生产系统矿井The design includes two parts: the design of parts and special parts. The general part of the preliminary design for the group An Ju 15Mt/a coal mine. An Ju coal mine is located in the central city of Jining City of Shandong Province, the new railway to the south, west of Beijing Hangzhou canal. The administrative division of Jining City District jurisdiction. Annual production capacity of coal mine is An Ju 15Mt/a, length of service for 63.7a. Working for the mine 330D, work system for four six system. Tape transport roadway used to transport coal, the mine auxiliary transport equipment. Mine ventilation way for the two wings of diagonal ventilation. . The mine coal mining methods for fully mechanized once mining full height, the length of working face 190m. The relevant state policies and the specific geological conditions of housing based on coal mine, this paper has completed the preliminary design work Anju mine. The main design and determine the development plan, the design of mining area and mine transport, ventilation, drainage systems. Keywords: preliminary design of mine; development design; the design of mining area; production system; mine ventilation and safety. 目录 1 矿井概述 1 1.1矿区概况 1 1.2 地质特征 3 2 矿井生产能力及服务年限 16 2.1开采范围及储量 16 2.2 矿井生产能力与服务年限 19 3井田开拓 23 3.1开拓方式及井口位置 23 3.2 井筒及井底车场 29 4 采区设计 37 4.1 采区地质特征 37 4.2 采区生产能力及服务年限 40 4.3 采煤方法及采区参数 40 4.4 采区巷道布置 43 4.5 采区车场及硐室 50 4.6 采煤工作面配备和生产能力验算 51 4.7 采掘工作 52 5 矿井通风与安全 63 5.1 矿井通风 63 5.2 井下灾害防治 77 6 矿井主要生产系统 89 6.1 矿井通风系统 89 6.2 矿井运输提升 94 6.3 矿井排水 109 7 劳动定员及主要技术经济指标 113 7.1 劳动定员及劳动生产率 113 7.2 矿井主要技术经济指标 113 专题：深井小煤柱护巷技术探讨 116 参考文献 127 致谢 129 附录：文献翻译 130 1 矿井概述 1.1矿区概况 1.1.1 交通位置 安居井田位于山东省济宁市市中区内兖以南，京杭运河以西井田北邻新乡铁路，东至济宁站约km，西至济宁西站约.6km，煤炭外运运输条件优越。 井田邻近济宁市，城区外环路、济宁鱼台、济宁金乡等公路均从井田内通过，公路交通运输便利。 京杭运河从井田东部通过，水运至南方也比较优越。1.1.2 地形地貌 井田内地形平坦，地势北高南低，地面高程+35m左右，地形坡度约0.4%，为一由西北向东南逐渐降低的滨湖冲积平原，井田东南部上覆南阳湖
