Mining yog lub hauv paus ntawm peb txoj kev lag luam ntawm Anglo American. Nws yog lub hauv paus tiv thaiv uas txhua yam ntawm peb cov dej num cia siab thiab gravitate ib ncig. Thiab yog vim li cas nws tseem ceeb heev uas peb ua peb hom kev ua haujlwm mining kom zoo thiab txawj ntse.

Thiab dab tsi yog txoj kev mining peb siv kom ncav cuag peb cov khoom sib txawv?

1. Qhib-qhov mining

Qhib-qhov yog ib txoj kev mining uas siv ntau tshaj plaws thiab pib los ntawm lub ntiaj teb' qhov chaw, tswj kev raug rau saum npoo thoob plaws lub sijhawm rho tawm. Lub excavation feem ntau yog stepped ob sab los xyuas kom meej kev ruaj ntseg ntawm cov miners thiab ib tug dav ramp qhov twg cov cuab yeej siv tau mus, tso cai rau cov khoom yuav raug tshem tawm zoo ntawm qhov chaw.

Qhov zoo ntawm qhov qhib-qhov mining muaj xws li:

1. Cov tsheb loj thiab shovels siv tau los txav cov pob zeb loj.

2. Cov cuab yeej tsis txwv los ntawm qhov loj ntawm qhov qhib koj ua haujlwm.

3. Kev tsim khoom sai dua.

4. Tus nqi qis rau kuv txhais tau tias qis dua ntawm cov ore yog kev lag luam rau kuv.

Cov duab yooj yim hauv qab no qhia txog cov xwm txheej ntawm qhov qhib-qhov mining voj voog.

2. Underground mining

Underground mining yog siv los rho tawm cov ore los ntawm hauv qab ntawm lub ntiaj teb kom nyab xeeb, kev lag luam thiab nrog me me pov tseg li sai tau. Kev nkag los ntawm qhov chaw mus rau hauv av hauv av yuav yog los ntawm kab rov tav lossis ntsug qhov, hu ua adit, ncej lossis poob.

Underground mining yog siv tau thaum:

1. Lub cev ore yog tob heev rau kuv profitably los ntawm qhib qhov.

2. Cov qib lossis qhov zoo ntawm cov orebody yog siab txaus los them cov nqi.

3. Underground mining muaj qhov qis dua hauv av dua li qhib qhov mining.

Underground mining yog dab tsi?

Txoj kev mining hauv av peb siv suav nrog chav tsev thiab ncej, nqaim cov leeg nres thiab cov tshuab ua haujlwm loj.

Chav thiab ncej miningyog ib qho style ntawm mining qhov twg tunnels yog tsav nyob rau hauv ib tug chess board qauv nrog loj loj square ncej nruab nrab ntawm lawv uas yog maj txiav tawm raws li kev ua hauj lwm. Peb siv qhov no rau mining thee.

Cov hlab ntsha nqaim nresyog ua nyob rau hauv ib tug underground excavation raws geological 'veins' - txawv daim ntawv-zoo li lub cev ntawm crystallized minerals nyob rau hauv lub pob zeb - qhov twg cov mineral yog mined thiab tshem tawm. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, peb yuav tsum ua qhov kev khawb av hauv av, peb kuj yuav tsum tau ua qhov kev khawb rau hauv lub cav thiab cov twj tso kua mis los yog rau kev siv xws li shafts, drives, winzes thiab nce. Peb siv qhov no rau mining platinum.

Loj loj mechanized miningcov txheej txheem peb siv suav nrog:

• ntev phab ntsa mining,qhov twg ib phab ntsa ntev ntawm cov thee yog mined nyob rau hauv ib daim hlab, feem ntau yog los ntawm lub tshuab loj.

• sub-level-caving,qhov twg theem ntawm cov ore raug blasted los ntawm cov khoom tawg; thiab

• block caving,qhov twg cov cheeb tsam loj ntawm lub cev ore raug blasted thiab muab rho tawm nrog kev pab ntawm lub ntiajteb txawj nqus.

Peb siv peb hom kev sib txawv hauv av hauv av rau cov thee, pob zeb diamond thiab tooj liab.

3. Underwater mining

Underwater mining yog tsim nyog thaum cov khoom uas koj tau txheeb xyuas nyob rau hauv ib tug dej ib puag ncig zoo li lub hiav txwv pem teb. Nws yog ib qho kev sib tw tshwj xeeb - thiab ib qho uas yuav tsum tau muaj kev lav phib xaub uas xav txog qhov kev xav hauv zej zog.

Peb ua underwater mining nrog lub hom phiaj-tsim ships siv ib tug remotely ua underwater tsheb los yog laum tshuab nyob rau hauv qhov tob ntawm 100-140 meters hauv qab no hiav txwv theem.
