Research on Stress Distribution of Deep Rock by Mechanical Impact Parameters
Domestic and foreign scholars have been studied rock characteristics , but the study results not nearly same with rock nonlinear characteristics. it different rock crushing test conducted many studies ,because it has not the rock broken theoretical basis .This paper try to study the deep rock distribution (under the load before static load) by concentrated load ,it is proposed for deep rock fragmentation theory and methods. In the rock is often under stress , the stress number is measure pressure ,the rock stress state is Related for the elastic potential energy stored and the energy is proportional to the rock depth and volume occurrence. when the stress turned from ,the rock energy will accumulate or release .when the rock energy release ,the rock particles displacement may be elastic displacement or plastic displacement.
