大坪金矿毛木树矿段250吨/日地下开采设计 摘要 本设计为华西元阳公司大坪金矿毛木树矿段V1-2-3矿体250吨/日地下开采设计。共分为11章：1.矿区概况及矿床地质；2.矿床开拓设计；3.盲斜井提升及盲斜井断面设计；4.矿山运输及平巷断面设计；5.阶段平面设计；6.井底车场设计；7.采矿方法设计；8.基建进度计划编制；9.矿山通风与安全技术；10.矿山排水；11.矿山动力供应。 本设计范围为545m~960m中段，矿体走向长3120m，平均倾角为78°，平均厚度为0.35m，矿体的上下盘为闪长岩，矿区地质条件简单。 矿井采用平硐加盲斜井开拓,开采760m以上阶段时采用平硐开拓，760m以下采用盲斜井开拓；采矿方法采用削壁充填法，主要包括崩落矿石与围岩、矿石搬运、架设顺路天井、充填工作；通风方式采用对角双翼式，主平硐进风，南北风井回风；采场内通风，两边顺路天井进风，采场中间的探矿天井回风；井底车场采用甩车道；矿山的运输方式采用电机车运输，盲斜井提升采用矿车组提升；矿山排水760m以上采用自流排水，深部采用分段接力式排水；矿山动力供应主要是空压机的选择。此外，还采用CAD进行辅助图形设计。 关键词：矿床开拓，削壁充填采矿法，矿井通风，矿井提升运输，矿山排水。 Daping gold mine Maomushu orebody 250 ton/day derground mining designs ABSTRACT This design for Huaxi Yuanyang Corporation Daping gold mine Maomushu ore section V1-2-3 orebody 250 ton/day derground mining designs. Altogether divides into 11 chapters: 1. Mining area survey and mineral deposit geology; 2. Mine development design; 3. Blind slope mine promotion and blind slope mine section design; 4. Mine haulage and driftway section design; 5. Horizon plane design; 6. Mine shaft station design; 7. Mining methods design; 8. Capital construction progress schedule establishment; 9. Mine ventilation and safety work; 10. Mine drainage; 11. mine power supply. This design scope is the 545m~960m center-section, the orebody moves toward long 3120m, the mean obliquity for 78°, the average thickness is 0.35m, the orebody about plate is the diorite, the mining area geological condition is simple. The mine pit uses the adit and blind slope mines development, mines above 760m when the horizon uses the adit development, the 760m following uses the blind slope mine development ; The mining methods use the inbreak wall rock flashing mine method, mainly includes the inbreak ore and the wall rock, the ore transporting, erects on the way the raise, the filling operation ; Mine ventilates the way to use diagonal ventilation, The main adit enters the wind, the north and south air shaft return air ; In the stope ventilates, two side raise enter the wind ,
