Combined with the occurrence characteristics of China’s low permeability coal seam and the advantages and disadvantages of various permeability enhancement technologies, the technical methods to improve the permeability of coal seam are classified and compared, and the technology, equipment, application effect, existing problems and defects and applicable conditions of each permeability enhancement method are systematically sorted out. The development trend of permeability enhancement technology is prospected, and it is pointed out that permeability enhancement technology will work in combination with various permeability enhancement methods, and permeability enhancement equipment will develop towards intelligent and unmanned direction.
