Coal can be mined through two main methods: surface or opencast mining and underground or deep mining. Surface mining involves removing overburden and extracting coal near the surface, recovering 90% of coal deposits. Underground mining uses room-and-pillar or longwall techniques to extract coal seams deeper underground, leaving behind pillars for roof support or fully …
