Electromagnetic emission theory and its application to dynamic phenomena in coal-rock

摘要

Coal-rock dynamic phenomena are often difficult to predict, and when they take place, they severely affect mine production and personnel safety. With the increasing depth of coal mines and the increasing extraction rates, the dynamic phenomena of coal-rock have become more serious [1]. Prediction of coal-rock dynamic phenomena is one of the key issues in coal mine safety. In order to predict such phenomena and improve the economic value of a coal mine, it is important to develop a robust and accurate prediction method, which would have no or little influence on interrupting the production cycle and can be done at an affordable cost.
