Limestone Makes for Cleaner Coal

Grants, New Mexico is a 90-minute drive into the high desert west of Albuquerque. Just south of Grants, C&E Concrete, Inc. is extracting a pure form of limestone that is ground into rock dust used by coal power plants to scrub exhaust emissions and for dust control in underground coal mines to prevent explosions.CDC Mining How Does Limestone Rock Dust Prevent Coal,Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.Formation of Limestone and Coal Compare Rocks,1 Formation 1.1 Formation Limestone is a sedimentary rock which is mainly made up of calcium carbonate. Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
