Thee yog ib lub pob zeb combustible dub los yog brownish-dub sedimentary pob zeb uas muaj cov pa roj carbon ntau thiab hydrocarbons. Thee tau muab cais ua ib qho chaw tsis muaj zog ntxiv vim nws siv ntau lab xyoo los tsim. Coal muaj lub zog khaws cia los ntawm cov nroj tsuag uas nyob ntau pua lab xyoo dhau los hauv hav zoov swampy.

Ib yam li ntawd, tej zaum koj yuav nug, Coal luv teb yog dab tsi?

Coal yog ib lub pob zeb tawv uas tuaj yeem hlawv ua cov pob txha pob txha. Nws feem ntau yog carbon tab sis kuj muaj hydrogen, sulfur, oxygen thiab nitrogen. Nws yog ib lub pob zeb sedimentary tsim los ntawm peat, los ntawm lub siab ntawm cov pob zeb nteg rau saum toj.

Tom qab ntawd, lo lus nug yog, yuav ua li cas peb thiaj li tau txais cov thee? Coal tuaj yeem muab rho tawm los ntawm lub ntiaj teb los ntawm qhov chaw mining lossis underground mining.
