A study on testing the effect of blasting releasing pressure based on drilling electromagnetic radiation
Abstract：The relationship between electromagnetic radiation signals of coal and rock and the stress was analyzed, and the regularity of distribution of electromagnetic radiation signals of coal and rock located in the front of working face was discussed, the drilling electromagnetic radiation inspection methods for the effect of burst releasing pressure was proposed and validated by Liangbei Mine 11061 working face thin coal area blasting in Henan Shenhuo Group. Re search shows that the stress state of surrounding rock mass in the working face has good correlation with electromagnet ic radiation intensity, pulse. The electromagnetic radiation signals can respond the coal mining face stress distribution and transferring ahead. Drilling electromagnetic radiation can test the effect of blasting releasing pressure and provide a new method for testing the effect of blasting releasing pressure.
