DESIGN OF INTRINSICALLY SAFE FIELD SOURCE SIGNAL TRANSMISSION DEVICE FOR ELECTRICAL METHOD MONITORING SYSTEM WITH ADAPTIVE GROUNDING RESISTANCE

Design of intrinsically safe field source signal transmission device for electrical method monitoring system with adaptive grounding resistance

Electrical monitoring technology is widely applied in mines with high risk of water inrush because of its high sensitivity to the change of coal resistivity.However, due to the complex working environment of the two lanes Eyeliner of the underground working face, the ground conditions between the different field source emission monitoring electrode
