Experimental research on the electrical parameters of coal mass under load

摘要

Coal or rock dynamic catastrophe is one kind of natural disaster induced by mining activities and phenomenon that coal or rock exerted by external stress results in dynamic effects and disaster consequences in a very short time. And coal or rock dynamic catastrophe has become worse than ever with deep coal seams being mined at higher production rate in a more complex underground deep mining environment, so it is very important for disaster prevention and reducing the losses caused by dynamic disaster to the minimum to accurately forecast coal or rock dynamic catastrophe.
