China has at least 200 collieries suffering from the problem of instantaneous outbursts of coal and gas. The strong outbursts often occurred in active tectonic lanes and areas of high stress concentration. In this paper, the author describes some characteristics of the strong outbursts and analyses the effects of ground stress, gas pressure and the properties of coal in outbursts.
