A model of one-dimensional coal gas outburst wave

In 1993, in consideration of seepage damage, two phase flow and air compression wave, a model of one-dimensional coal gas outburst constant advance is published by Cheng Z M, etc., and in 1997 in view of air-solid mixed phase flow a strength discontinuity model published by Yu S B, etc. Based on the above researches, considering in factors of seepage damage, strength discontinuity of mixed phase flow and air compression wave, the paper proposed a new one-dimensional coal gas outburst constant advance. By the model, numerical simulations are in accord with the experimental results.
