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.

Secrets About Mining Herkimer Diamond Quartz Crystals

Herkimer Diamond Geology and Geography. The host rock of "Herkimer diamonds" is the Cambrian-age, Little Falls Dolostone. The Little Falls Dolostone was deposited about 500 million years ago, and the "Herkimer diamonds" formed in cavities within the dolostone.These cavities are frequently lined with drusy quartz crystals and are often coated with a tarry hydrocarbon.

Quartz Wikipedia

Quartz belongs to the trigonal crystal system.The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned (with twin right-handed and left-handed quartz crystals), distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces
