摘要
本次設(shè)計的大寶山銅硫鐵礦位于廣東省韶關(guān)市曲江縣,它是一個比較大型的多金屬國有企業(yè),其礦石成品主要為銅、硫、鐵礦石。
本設(shè)計共分為6個部分,它們分別是:(1)總論;(2)礦床賦存地區(qū)的自然概況及原始資料(3)礦床地質(zhì);(4)開拓系統(tǒng);(5)采礦方法;(6)礦山通風(fēng);(7)礦山提升和運輸。根據(jù)大寶山具體的礦床地質(zhì)條件、礦床開采條件采礦方法采用垂直礦體走向的有底柱中深孔分段鑿巖階段礦房法。其大寶山擬設(shè)計的生產(chǎn)能力為.52.8萬噸/年,選用該采礦方法的礦石回收率、損失率、貧化率分別為:85%、10%、15%。通風(fēng)方式采用愁出示對角通風(fēng),開拓系統(tǒng)采用大寶山原來的開拓系統(tǒng),運輸提升采用主斜井箕斗加副斜井提升。
此次設(shè)計專題部分為地下采礦方法單體設(shè)計,首先是采礦方法的技術(shù)經(jīng)濟比較,然后選定一種采礦方法,再根據(jù)選定的采礦方法進行設(shè)計,鑿巖采用YGZ-90鑿巖機打上向扇形中深孔,采場通風(fēng)為4.5m3/s,采空區(qū)采用長錨索支護之后進行嗣后一次充填。
關(guān)鍵詞:開拓系統(tǒng);礦床地質(zhì);分段鑿巖階段礦房法;
ABSTRACT
The da bao shan copper and sulphur iron mine of the design locates at shaoguan country in Guangdong pass city song river County, it is a more large many business enterprises with state-owned metals, its mineral stone finished product is mainly
copper, sulphur, iron mine stone.
This design is divided into 6 part totally, they respectively is:(1)General introduction;(2)The mineral bed endows with the natural general situation and the original data(3) mineral bed geologies of the regions;(4) Developmengt system;;(5)mining method;(6)Mineral mountain airiness;(7)The mineral mountain promotes and transports.Mine the opencast method of condition to adopt the perpendicular mineral body to head for according to the concrete mineral bed geology condition, the mineral bed of big treasure mountain have the bottom pillar to dig the rock stage mineral building method in the segment of cent of deep bore.Its big treasure mountain draw up production ability of design is.528,000 tons/ years, which choose to use mine for the mineral stone recovery rate of method and lose the rate, poverty to turn the rate difference is:85%,10%,15%.The well ventilated way notice the opposite angles well ventilated, expand the big treasure mountain of the system originally, the conveyance promotes to adopt the main and inclined well skip to add the vice- inclined well to promote.
This time the design of special subject designs the single body of underground opencast method,which is a technique economy that substitute for minerals the method to compare first, then make selection a kind of opencast method, carry on the design according to the opencast method for making selection again, digging the rock for adoption rock drills YGZ-90s to beat up to fan-shaped in deep bore, adopting an airiness as 4.5 m3s/ s, adopting empty area adoption the long anchor cable carries after pay protect to fill later.
Key words:Development system;Mine geoclogy;sublevel open-stoping;
