【摘要】 对现有的煤与瓦斯突出机理研究成果进行了评述;阐述了煤与瓦斯突出机理的研究思路与方法及其历史发展过程和研究现状;分析了这些研究成果的不足之处,提出了煤与瓦斯突出机理的研究方向。研究表明,煤与瓦斯突出机理已经从单因素向多因素发展,综合作用假说得到了普遍认可,这为防突工作提供了理论依据。认为,煤与瓦斯突出准备机理、失稳与平衡机理、发展机理、传播机理和煤与瓦斯突出带分布规律研究是煤与瓦斯突出机理需要深入研究的方向。更多还原

【Abstract】 In order to discuss the orientation of research on coal and gas outburst mechanism,research findings of coal and gas outburst mechanism were presented in this paper,Different thoughts and methods of research on coal and gas outburst mechanism were expounded,so were the processes of development and current situation of research on coal and gas outburst mechanism.Limitations of existing research findings on coal and gas outburst mechanism were analyzed.Orientation of research on coal and gas outburst mechanism was proposed as well.Currently,research on coal and gas outburst mechanism has developed from single-factor level to multiple-factor level and hypothesis of comprehensive function of multiple-factor has received wide acceptance,which has built theoretical basis for outburst prevention measures in coal mine.Domestic researchers have made abundant achievements in the research on mechanism of coal and gas outburst,which has advanced and developed the mechanism.It was believed that the mechanisms of outburst preparation,outburst instability and balancing,outburst development,outburst transmission of coal and gas,as well as the regularity of distribution of regions where coal and gas outburst tend to take place are the research orientation for deepened study of the mechanism of coal and gas outburst.更多还原
