摘　　要：对煤与瓦斯突出发生的综合作用机理及治理技术进行总结,从宏观上提出治理煤与瓦斯突出的技术手段;分析总结我国综采放顶煤开采的技术成果,讨论了工作面应力分布规律和顶煤变形规律对突出的影响;认为:具突出危险性的厚煤层采用综采放顶煤开采法对消突是有积极作用的.First, the paper gives a summary description of the coal-gas outburst mechanism, its prevention and control measure and the key technical of the measure. Then, it summarizes the thchnology achievement of fully mechanized coal caving mining, and discusses the stress distribution of fully mechanized caving face and top coal deformation effect on coal-gas outburst. Finally, the paper considers that the fully mechanized coal caving mining is helpful to control outburst hazard.
