Kev ua haujlwm tsuas yog hais txog ntau yam kev ua haujlwm mining thiab ntau lawm ua haujlwm hauv mines lossis mining sites.Kev lag luam mining npog txhua yam ntawm kuv qhov kev tshawb nrhiav, kev tsim kho, mining, kev ua, kev thauj mus los, thiab lwm yam., aiming los hloov av los yog nto ore, ore xuab zeb los yog cov ntxhia hauv cov khoom siv ntxhia.
Cov txheej txheem ntawm kev ua haujlwm mining feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:
Kev Tshawb Fawb: Los ntawm kev tshawb nrhiav geological kev ua ub no, txiav txim siab txog geological tej yam kev mob ntawm mines, txiav txim siab cov peev txheej ntxhia thiab cov peev txheej tshwj xeeb, thiab tsim cov phiaj xwm mining tsim nyog.
Pretreatment: Nrog rau kev ua ub no xws li kev soj ntsuam geological, sampling tsom xam thiab kev sim kom nkag siab qhov xwm thiab zoo ntawm ore, thiab muab cov ntaub ntawv tsim nyog thiab cov ntaub ntawv rau kev tshawb nrhiav thiab kev ua haujlwm tom ntej.
Kev tsim kho: Raws li kev tshawb nrhiav, xaiv cov kev tsim kho mining thiab cov cuab yeej siv mining, thiab ua cov kev tsim kho hauv mining, xws li txoj kev, tunnels, mines, cov kav dej, thiab lwm yam, los npaj rau kev ua haujlwm mining tom ntej.
Mining: Raws li txoj kev npaj tsim kho, siv cov cuab yeej siv mining tsim nyog thiab thev naus laus zis los ua cov mining thiab thauj ore.Txoj kev tsuas tuaj yeem muab faib ua ob hom: underground mining thiab open-pit mining.Cov txheej txheem tshwj xeeb suav nrog
1. Kev mining hauv av yog hais txog ib txoj hauv kev mining uas cov pob zeb hauv av tau txais los ntawm kev khawb cov mines hauv av.Cov ore yog khaws cia rau hauv gangues thiab cov hlab ntsha excavated underground, thiab cov miners coj cov ore tawm hauv av los ntawm kev nkag mus rau hauv av rau drilling, blasting, tunneling thiab lwm yam kev khiav hauj lwm.Lub ntsiab tseem ceeb ntawm cov mining hauv av yog tias nws yuav tsum tau ua haujlwm hauv qhov chaw hauv av, uas yuav tsum tau muaj kev nyab xeeb siab rau cov mines thiab cov khoom siv cuam tshuam, thiab tib lub sijhawm yuav tsum tau daws cov dej ntws, qhov cua, kev nyab xeeb thiab lwm yam teeb meem.
2. Surface planing yog ib txoj hauv kev los ntawm mining ore rau saum npoo.Txoj kev no feem ntau siv tau rau cov xwm txheej uas cov ore reserves loj, dav dav, thiab cov txaj ore yog ntiav.Hauv kev npaj nto, cov ore yog nyob rau hauv pob zeb lossis av ntawm qhov chaw, thiab cov txheej txheem tsuas yog tshem tawm cov ore los ntawm pob zeb lossis av los ntawm kev npaj los yog blasting.Qhov kom zoo dua ntawm txoj kev no yog kev siv mining siab thiab tus nqi qis, tab sis vim tias nws tau ua tiav ntawm qhov chaw, cov teeb meem xws li kev ua haujlwm hauv av thiab kev tiv thaiv ib puag ncig yuav tsum tau daws.
3. Qhib-qhov blasting yog ib txoj kev ntawm crushing thiab sib cais ore siv explosives nyob rau hauv qhib-qhov mines.Cov ore yog sib cais los ntawm cov pob zeb los ntawm kev ua haujlwm blasting rau cov mining tom ntej thiab ua tiav.Cov txheej txheem ntawm kev qhib cua blasting feem ntau muaj ntau qhov sib txuas xws li xaiv cov khoom tawg uas tsim nyog, npaj cov fuzes, tswj blasting quab yuam, thiab ua kom muaj kev ruaj ntseg blasting.Txoj kev no muaj cov yam ntxwv ntawm cov ore crushing efficiency thiab cov txiaj ntsig zoo, tab sis nws kuj yuav tsum tau ntxiv dag zog rau kev saib xyuas thiab kev ntsuas kev nyab xeeb ntawm cov txheej txheem blasting kom tsis txhob muaj kuab paug ib puag ncig thiab kev nyab xeeb.
Txawm hais tias underground mining, deg Planing thiab nto blasting yog peb txoj kev sib txawv mining, lawv txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.Nyob rau hauv daim ntawv thov, raws li cov yam ntxwv ntawm geological, reserves, economic kev pab cuam, kev tiv thaiv ib puag ncig thiab lwm yam tseem ceeb ntawm cov ore, qhov zoo tshaj plaws mining txoj kev yog xaiv los mus ua kom tiav qhov siab tshaj plaws kev siv thiab sustainable kev loj hlob ntawm mineral peev txheej.
Kev Ua Haujlwm: Crushing, sib tsoo, thiab cov txiaj ntsig tau ua tiav ntawm cov mined ore kom rho tawm cov khoom siv hlau, cov zaub mov lossis cov ore, tshem tawm cov impurities, thiab tau txais cov khoom ntxhia zoo.
Kev Thauj Mus Los: Thauj cov khoom siv pob zeb ua tiav rau cov chaw ua haujlwm, cov neeg siv kawg lossis xa tawm los ntawm cov khoom siv thauj mus los (xws li conveyor siv, railways, tsheb thauj khoom, thiab lwm yam).
Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: Kev ua haujlwm hauv mines yuav tsum ua raws li cov kev cai tiv thaiv ib puag ncig thiab cov qauv kev nyab xeeb, ua kev ntsuas los txo qhov cuam tshuam rau ib puag ncig, thiab xyuas kom muaj kev nyab xeeb thiab kev noj qab haus huv ntawm cov neeg ua haujlwm.
Feem ntau hais lus, kev ua haujlwm ntawm kuv yog txoj kev sib txuas thiab ntau qhov txuas, suav nrog kev paub thiab thev naus laus zis hauv ntau thaj chaw xws li geology, engineering, machinery, ib puag ncig, thiab lwm yam. Nws aims kom paub txog kev ua haujlwm mining thiab ua cov khoom siv ntxhia thiab muab cov khoom tsim nyog minerals.
