摘　　要：高瓦斯矿井进入深部开采后,回采工作面容易诱发冲击矿压与突出复合型灾害,对采矿安全构成重大威胁。通过分析采煤活动过程中回采工作面应力分布状况,运用尖点突变理论建立了冲击与突出耦合尖点突变模型,并分析了灾害发生后的能量释放大小及其主要影响因素,加深对了冲击矿压与突出耦合规律的认识,对于有效地预防复合型矿井灾害发生具有重要意义。With the increasing of exploiting depth at High Gas Mine,rock-burst and outburst compound disasters were induced easily in coal mining face,it is a major menace to mining safety.In this thesis the cusp catastrophe model about bumping and outburst coupling danger in coal mining face was established base on the theory of cusp catastrophe,through analyse the condition of the stress distribution in coal mining face during the process of coal mining.The energy release rate and it＇s main influence factors after disaster happened were analyzed also.Better understanding of the coupling rule of rock-burst and outburst was obtained.It has importance significance on preventing rock-burst and outburst compound disasters in coal mining face.
