Abstract

In order to understand the relation between advance rate of single seam working face and gas drainage volume, the parameter of gas concentration, differential pressure, temperature, absolute pressure is measured in gas drainage pipelines after highly or low-located holes gas drainage method is adopted in 1306 working face to the strike. The relation between advance rate of single seam working face and gas drainage volume is put forward by means of regression analysis method. The study results show that gas drainage volume in 1306 working face is in turn rising slowly, rising quickly then slowly, and stabilizing totally with the stoping of working face. As the number of boreholes is continually increased, gas drainage volume in working face is not significantly increased when advance rate is more than 80 m, and boreholes with low gas concentration and low mixing flow must be closed in time.
