This paper introduces the testing technology of dynamic (potential) method to determine the azimuth and length of coal seam fracturing. It is based on the inherent characteristics of coal seam and conducts a large number of physical model tests indoors. Combining with the scientific research achievements after the field test. Based on the basic principles, measurement methods and measuring instruments of the dynamic (potential) method, this paper mainly analyzes the field application effects of the well Jixit 1 in Shanxi Province and West 36- 10-3 well in Dagang Oilfield, and proves that the dynamic Potential) test technique and its important role in exploration and development of coalbed (oil) gas fields
