    Research status and prospect of water inrush mechanism and prevention of coal seam floor in China

    • In view of the problem of water inrush from coal seam floor in China, the application effect of water inrush prevention measures of coal seam floor in recent years, such as the research on the mechanism of water inrush from coal seam floor under various conditions of different geological structures and high aquifer water pressure in China, and the widely used floor grouting reinforcement technology, the establishment of fault waterproof coal pillar and the drainage and pressure reduction before mining are summaried and analyzed, the shortcomings of the research on water inrush from coal seam floor are pointed out. The prospect of large mining depth, complexity, low cost, green, high efficiency and intelligent control of water inrush from coal seam floor is proposed.
