前言随着开采深度加大,揭露含水层数量增加和距强含水层近的煤层开采,矿井突水次数及突水量增加,以致淹井事故日趋频繁,因此受岩溶裂隙水威胁煤层的突水机理研究和防治水已成为影响煤矿安全生产极待解决的重大课题。底板岩溶裂隙水突破保护层进入矿井即“突水”,由于各研究者着眼点不同而分类法各异,如将突水分成:掘进的和回采的;瞬时的和滞后的,弱的和强的;一般的和灾害性的,等等。 Preface As the mining depth increases, exposing the increase in the number of aquifers and coal mining near the strong aquifer, the number of water inrush and the amount of water inrush increase, resulting in more frequent flooding accidents, so karst fissure water is threatened by water inrush mechanism Research and prevention and control of water has become a major issue to be solved in the safety production of coal mines. The floor karst fissure water breaks through the protective layer and enters the mine pit, ie, “water inrush”. Due to different researchers’ different viewpoints, the taxonomy varies. For example, the inrush water is divided into: heading and recovery; momentary and lagging, weak and strong The general and the catastrophic, and so on.
