Application of Electromagnetic Radiation Monitoring Equipment in Monitoring and Warning of Coal and Gas Outburst

Abstract

In order to systematically describe the electromagnetic radiation monitoring and early warning technology and application status of coal and gas outburst, the paper analyzes in detail coal and gas outburst electromagnetic radiation monitoring technology equipment and application from three aspects: the basic principles and methods of coal and gas outburst prediction by electromagnetic radiation, electromagnetic radiation monitoring and early warning equipment and systems, and electromagnetic radiation prediction outburst field application. Results show that electromagnetic radiation responds well to the outburst hazard of working face, gas geology and abnormal stress. It is an effective non-contact geophysical monitoring and early warning method of coal and rock dynamic disasters, which has a good development prospect in highlighting the forecast.
