煤与瓦斯突出研究现状及分析

Present analysis and study on coal-and-gas outburst

阐述了煤与瓦斯突出机理的研究现状和基本特征，分析了煤与瓦斯突出机理研究中存在的问题。研究表明，煤与瓦斯突出机理的影响因素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。煤与瓦斯突出特征、物理模型的近似定量化及数值模拟、现场防突测评等方面还需要进一步深入研究。

In this paper, the research status and basic characteristics on coal and gas outbursts mechanism was expounded and the existing problems was analysed. It showed ,that coal and gas outbursts has developed from single-factor to multiple factors level and hypothesis of comprehensive function of multiple-factor is widely accepted, which provides theoretical basis for outburst prevention measures in coal mine. the coal and gas outbursts characteristics, approximate quantification of physical model, numerical simulation and evaluation of spot outburst prevention still need further study.
