| Abstract: | The soft seams are distributed widely in China;the drilling equipment and gas geological drilling have formed a relatively complete system with air drilling technology.By the application of air drilling in many coal mines,good technical effects have been achieved in drilling depth and hole diameter and a longer gas extraction time of a borehole. |

| Keywords: | soft coal seam air drilling equipment and technology mechanism and method |
