Abstract: With the gradual deepening of the development, the permeability of the coal seam is reduced, the gas content and gas
pressure are increasing, and the outburst disaster is becoming more and more serious. The effect of gas drainage in low
permeability coal seams is improved by taking measures such as optimizing the process of increasing permeability and sealing
holes, exploring the relation of negative pressure and flow, and optimizing the drainage system. This paper discussed the
improvement technology of gas drainage effect for low permeability coal seams in Anyang mining area.

Key words: regional gas control; mechanical reaming; optimization of hole sealing technology; relation of extraction parameters;
