| Abstract: | Abstract It is a new practical method to predict outburst danger according to gas emission law after shotfiring at coal heading faces. In this paper a theroetical analysis is made on the gas emission law,seeking the relative factors and the degree of their influence. Field experiments have been carried out in Bejjiao Coal Mine to select rational prediction index. Some valuable experiences has been obtained as well as the basic method to preliminarily determine the index of V30 |
