China is one of the countries with the most frequent coal and gas outburst accidents in the world. In the early years of the founding of New China, coal and gas outburst accidents occurred frequently, causing serious casualties, equipment damage, and economic losses. In recent years, some scholars have tried to simulate the coal and gas outburst phenomenon using physical models to study the mechanisms of its occurrence. However, due to the complexity and nonreproducibility of coal and gas outburst disasters, the study of coal and gas outburst mechanisms 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 have emerged and achieved remarkable results, and the probability of coal and gas outburst accidents has been greatly reduced. Among coal and gas protrusion outburst and control technologies, hydraulic and anhydrous prevention and control technologies are widely used. The purpose of this paper is to briefly explain the mainstream hypothesis of coal and gas outburst, analyze the action principle of hydration and anhydrous control technologies, discuss the current status of research on hydration and anhydrous control technologies, and put forward the problems of current technologies and future development trends.
中国是世界上煤与瓦斯突出事故最为频发的国家之一。新中国成立初期，煤与瓦斯突出事故频繁发生，造成了严重的人员伤亡、设备损坏和经济损失。近年来，一些学者试图利用物理模型模拟煤与瓦斯突出现象，研究其发生机理。然而，由于煤与瓦斯突出灾害的复杂性和不可重复性，煤与瓦斯突出机理的研究仍处于假说阶段。为有效降低煤与瓦斯突出事故风险，煤与瓦斯突出防治技术应运而生并取得显著成效，煤与瓦斯突出事故发生概率大幅降低。在煤与瓦斯突出防治技术中，水力和无水防治技术应用广泛。本文旨在简要阐述煤与瓦斯突出的主流假说，分析水力和无水防治技术的作用原理，探讨水力和无水防治技术的研究现状，并提出当前技术存在的问题及未来发展趋势。
