摘要：

According to the principle of Geo-dynamic Division method, the regional prediction of gas and coal outbursts is introduced in this thesis. Firstly, the influence of tectonic stress field on gas and coal outbursts is discussed. After active faults are determined, the geological structure model of minefield is formed, then the stress distribution in rock mass is calculated by the Finite Element method. On the basis of the calculation results, we can divide the stress abrupt change zones, which are the places where gas and coal outbursts occur easily. So the Regional prediction can be carried out accurately, which can be a guide to set down the corresponding preventive measures. The method researched in this thesis has wide application prospect.
