The results presented in this paper are a successive contribution to investigations on the couse of gas and coal outbursts phenomena, initiated under laboratory conditions. The paper presents results of experiments carried out in order to assess the impact to pressure wave reflected from the open end of the pipe on the course of the outburst. Results of subsequent experiments were divergent. Installation of additional manometers revealed assymmetry of the outburst front despite axial symmetry of the experimental stand and coal briquette. The cause of this asymmetry was briquitte. An improved design of the head was described.
