The Application of Potential Method in Monitoring of Coal Mine Gas Fracturing

摘要

Poor permeability coal seams in Southern Ordos Basin,well gas drainage in mining area has become the primary method of disaster treatment.In this paper,we take using dynamic monitoring technology using high power potential method to measure potential gradient to monitor the process of gas well fracturing,in order to speculate the fracturing precursor edge.The results of high power potential method for mining coal mine gas monitoring fracturing shows that fractttfing fluid distribution can be drawn from the scope of the fracturing process to assess.
