水力化防治煤与瓦斯突出技术研究现状

Research status of hydraulic coal and gas outburst prevention and control technology

我国是容易发生煤与瓦斯突出事故的国家之一。近年来,一些学者尝试利用物理模型模拟煤与瓦斯突出现象,研究其发生机理。但由于煤与瓦斯突出灾害具有复杂性、不可再现性等特征,煤与瓦斯突出机理研究仍处于假说阶段。为了有效降低煤与瓦斯突出事故的危险性,煤与瓦斯突出防治技术应运而生,并且取得显著成果,煤与瓦斯突出事故发生概率大大降低。在煤与瓦斯突出防治技术中,水力化防治技术被广泛应用。本文旨在简要阐述煤与瓦斯突出的主流假说,分析水力化防治技术的作用原理,探讨水力化防治技术研究现状,并提出目前技术存在的问题以及未来发展趋势。

China is one of the countries prone to coal and gas outburst accidents.In the early days of the founding of the People's Republic of China,prominent accidents occurred frequently,causing serious casualties,equipment damage and economic losses.In recent years,some scholars have tried to use the physical model to simulate the phenomenon of coal and gas outburst and study its mechanism.However,due to the complexity and non-reproducibility of coal and gas outburst disasters,the research on the mechanism of coal and gas outburst is still in the hypothesis stage.In order to effectively reduce the risk of coal and gas outburst accidents,coal and gas outburst prevention and control technology came into being,and achieved remarkable results,the probability of coal and gas outburst accidents is greatly reduced.In the prevention and control technology of coal and gas outburst,hydraulic prevention and control technology is widely used.The purpose of this paper is to briefly explain the mainstream hypothesis of coal and gas outburst,analyze the action principle of hydraulic prevention and control technology,discuss the research status of hydraulic prevention and control technology,and put forward the existing problems and future development trend of the current technology.
