| Abstract: | In this paper,gas drainage experiments at the tunneling working face in gassy coal seam were carried out and investigated.The proper parameters of long drilling in the tunnel wall were provided.A new method of deep hole presplitting was suggested to enhance the air permeability and improve the gas release efficiency.The results show that this method reduces the outburst risk and increases the driving progress greatly. |
