Layers found in rocks
WebThe process of cutting rocks with a boom-type roadheader results in extreme dynamic loads and vibrations. Mining, especially in the case of hard rocks, is associated with large energy consumption, which, when combined with low process efficiency, can lead to low drilling performance. These phenomena are undesirable because excessive dynamic load leads … WebOriginal Rock: granite, gabbro. Environment: Gneiss forms at high temperatures and pressures. The temperature needed is about 700°C and the pressure needs to be about 12-15 kilo bars, which is at a depth of about 40 km! Distinguishing Characteristics: banded with alternating layers of dark and light minerals.
