Underground Coal Gasifi ion: An Overview of Groundwater

Underground coal gasifi ion is the in situ conversion of coal into an energy-rich product gas. It takes place deep underground, using chemical reactions to consume the coal and grow a cavity. Gas wells, drilled into the coal seam, inject reactant air, oxygen, and/or steam to sustain the reactions. Production wells then extract the product gas.

Coal mining - Wikipedia

Open cut hazards are principally mine wall failures and vehicle collisions; underground mining hazards include suffo ion, gas poisoning, roof collapse, rock burst, outbursts, and gas explosions. Firedamp explosions can trigger the much-more-dangerous coal dust explosions, which can engulf an entire pit.

The roof of a mine can collapse and cause rocks and debris to become unstable and possibly strike workers. Sometimes collapses are scheduled and systematically planned and control the hazard of a cave in. Appropriate safety plans will need to be practiced and workers should be trained on what to do in case of a cave in or a collapse in the mine.
