摘　　要：构造应力、能量集中与采动应力叠加,是煤瓦斯突出的根本原因,是现今构造活动的表现,由现今地壳失稳所致,属于地质力学问题。借鉴李四光倡导的地震地质工作经验,从现今活动构造体系研究入手,采用岩石力学与构造应力场的研究思路方法、技术,结合地壳稳定性评价实践经验,探索煤瓦斯突出减灾防灾的基本思路。The overlapping of tectonic stress, rock mass energy concentration and mining-induced stress is the basic cause for coal and gas outbursts. Coal and gas outbursts, which are one of the manifestations of present tectonic activities and induced by crustal instability, belong to the research content of geomechanics. It is a good way to explore the basic idea of prevention and reduction of hazards caused by coal and gas outbursts by using the experience in seismogeological work initiated by Prof. J. S. Lee for reference, beginning with the study of present active tectonic systems and using the methodology and technology of rock mechanics and tectonic stress field, combined with the practice and experience of crustal stability assessments.
