Technical Measures for Prevention of Coal and Gas Outbursts on Coat Pace

本文提出了防治煤与瓦斯突出的几种常见措施,从中解析了当前措施的缺陷、弊端,分析了高压水力冲孔对防治煤与瓦斯突出的原理,以及其作用效果。

The paper first presents a summary of the technical measures that are generally used for the prevention of both coal and gas outbursts, and then points out the drawbacks and insufficiencies of the methods currently adopted. Following that, the working principle of the high-pressure hydraulic hole flushing method and its effect in practical use are introduced.
