Kev daws teeb meem rau cov pa phem hauv mining
Kev lag luam mining yog hais txog kev rho tawm cov khoom tsim tawm xws li cov khib nyiab (xws li cov thee thiab cov zaub mov), kua (xws li cov roj crude), los yog gases (xws li natural gas). Cov haujlwm no suav nrog kev ua haujlwm hauv av lossis sab saud hauv av, kev ua haujlwm ntawm cov mines, thiab tag nrho cov haujlwm pabcuam feem ntau ua los ntawm lossis ze rau qhov chaw mining tsom rau kev ua cov khoom siv raw, xws li kev sib tsoo, kev pabcuam, thiab kev ua haujlwm. Nws tseem suav nrog kev npaj ua haujlwm yuav tsum tau ua kom muaj kev muag khoom ntawm cov khoom siv raw.
Ntau yam teeb meem gases (xws li methane, carbon dioxide, carbon monoxide, nitrogen, hnyav hydrocarbons thiab lawv cov tebchaw feem ntau hu ua biogas, xws li ethane, propane, butane, thiab lwm yam) uas khiav tawm ntawm cov thee seams, pob zeb txheej, thiab qhov chaw nyob ib puag ncig cov pob zeb hauv qhov. yog gases uas tsim los ntawm ib tug loj npaum li cas ntawm cov nroj tsuag deposits faus tob underground nyob rau hauv qhov kev txiav txim ntawm kub thiab siab nyob rau hauv lub tsim nyob rau hauv anaerobic tej yam kev mob thaum lub sij hawm metamorphism thiab carbonization txheej txheem ntawm thee.
