煤岩瓦斯复合动力灾害机理研究进展与展望

随着我国煤矿快速进入深部开采,煤岩瓦斯复合动力灾害日渐成为威胁深部煤炭安全高效开采的重大灾害,研究其发生机理成为煤矿安全领域新的重大科学问题。本文首先在调研统计的基础上,阐述我国煤岩瓦斯复合动力灾害的发生规律和主要破坏特征,从定性和初步定量研究角度对煤岩瓦斯复合动力灾害机理的研究现状进行综述分析,然后介绍笔者近年来在受载含瓦斯煤岩组合体耦合失稳诱发复合动力灾害机制方面的研究进展,最后展望煤岩瓦斯复合动力灾害机理研究中亟待解决的问题及未来研究方向。

Research Progress and Prospect on Coal-rock-gas Compound Dynamic Disaster Mechanism

With the rapid development of deep coal mining in China,the coal-rock-gas compound dynamic disaster has become a major disaster threatening the safety and efficiency of deep coal mining.It has become a major scientific problem in the field of coal mine safety to study the disaster occurrence mechanism.In this paper,firstly,on the basis of investigation and statistics,the occurrence law and main failure characteristics of coal-rock-gas compound dynamic disaster in China were expounded.The current research status of the compound dynamic disaster mechanism was reviewed from the perspective of qualitative and preliminary quantitative research.Then,the research progress on the coal-rock-gas compound dynamic disaster mechanism induced by the coupled instability of the gas-bearing coal-rock combination under load was introduced.Finally,the urgent problems in researching the coal-rock-gas compound dynamic disaster mechanism and future research directions were prospected.
