Abstract: Intensify foam was proposed to prevent the gas accumulation in upper corner of coal face.A new foam enhancer to improve foam performance were developed in the experiment,the best foaming agent were found according to the experiments about the foam properties and the Synergy of the foam enhancer of the three selected foaming agents and their complex.At the same time,interrelated experiments on the filling foam which was influenced by the mass fraction of foaming agent,foam enhancer were done.The results show that the properties of the filling foam are the best when the mass fraction of foaming agent,foam enhancer are 5% and 1% respectively.And based on the research in the laboratory,the filling foam has been successfully applied in some mines of Huaibei Mining Bureau,the results is good.
