Thermal spalling drills such as jet-piercing and forced-flame drills heat rocks to 370 to 540°C (700 to 1000°F) to create thermal stresses that spall the rock ().These devices have limited application because most rocks will not thermally spall (Maurer, 1968, 1980). Melting and vaporization drills utilize high-temperature devices such as lasers or electron beams to melt and vaporize rock ().

Standard Weights for Crushed Rock Per Meter | Hunker

General Weights. Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.
