 CO2 outburst is a main geological disaster in coalmines. A survey of study on CO2  outbursts at home and abroad and the latest developments in research of China are introduced in this paper.
    The CO2  outburst in the Lower Silesia Coalmine in Poland is the most serious in the world. In China,the extraordinary outburst of CO2 gas happened on  May 24,1978 in the Yaojie Coalmine,GansuProvince. In the recearch work of Yaojie,we launched study on some forward domains. Such as helium and argon isotopes , fission一track dating of calcite veins,thermal simulated experiment and so on , and got some new data and new results.
