山西省晋城煤业集团成庄煤矿矿井初步设计

摘 要

本设计矿井的井田面积为29.96平方千米,年产量300万吨。井田内煤层赋存比较稳定,煤层倾角,平均3°,煤层厚度平均8.0m。井田范围内整体地质条件比较简单,断层较发育,但均是小断层。矿井瓦斯含量较高,为高瓦斯矿井,矿井涌水量不大。根据实际的地质资料情况进行井田开拓和准备方式的初步设计,该矿井决定采用双斜井两水平上下山开采,采用带区式开拓方式。设计采用综合机械化放顶煤回采工艺,倾斜长壁采煤法,用全部跨落法处理采空区,并对矿井运输、提升、排水和通风等各个生产系统的设备选型计算,以及对矿井安全技术措施和环境保护提出要求,完成了整个矿井的初步设计。矿井全部实现机械化,采用先进技术和借鉴已实现高产高效现代化矿井的经验,实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。

关键词:倾斜长壁 放顶煤 综合机械化 高产高效

Abstract

These designed allotment area for 29.96 square kilometers,Yearly Output three-hundred trillion. Allotment intrinsically ocurrence of coal seam compare stabilize,coal seam pitch is under fifteen acid,average coal seam pitch is three acid.Coal seam thick is 8.0m,integrally nature condition compare simplicity,at allotment scope east normalizing function of the stomach and pleen center equal have got dislocation upgrowth. Both methane and carbon dioxide content relatively do not high, and neither do inflow of water no large either. On the basis of Preliminary Design,said shaft opt in adopt three vertical shaft fluctuate mountain exploitation,coal seam grouping band region fluctuate mountain co- disposal 'mode of opening,design adopt comprehensive mechanization full-seam mining stopper art,incline longwall method,treat goaf with whole straddle alight law from actual geologic information instance proceed allotment exploit and stand-by mode. The Preliminary Design of the both both combine versus mine haul, shaft exaltation, shaft drain and ventilation of mines isopuant systemic equipment lectotype count,as well as versus shaft technical safety measures and environmental protection claim,complete wholly shaft. Both shaft whole realize mechanization,adopt advanced techniques and use for reference afterwards realize high yield highly active modernization shaft 'experience,realize one mine not both high yield highly active shaft thereby run up to favorable economic benefit and social benefit.

Keyword:incline length wall full-seam mining comprehensive mechanization high yield highly active
