Experimental research of rock's charge induction under different temperature
Abstract：Using the test system of rock's charge induction influence on temperature,studied the characteristics and rules of rock's charge induction under different temperature.From the experiment observed,began to have signal of charge induction when granite and sandstone at about 30 ℃.As the temperature rise further,the temperature of granite reaches 150 ℃ and the temperature of sandstone reaches 100 ℃,the signal of charge induction increases rapidly.The results show that rock exists threshold value with the temperature change.Study of charge induction of rock has a certain effect on a further research the producing mechanism of coal rock burst charge.
