| 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. |
