[0002] In the process of coal mining, coal mine roadway water inrush is a common and intractable problem. The geological environment where the coal mine roadway is located is complex, rich in underground water system, when the original geological structure is damaged by mining operation, underground water will rush into the roadway. Small water inrush is relatively small in water volume compared with large water inrush, but if not timely and effective treatment, it will also have serious impact on the safety production and normal operation of coal mine.

First of all, in the aspect of plugging water inrush, there is lack of effective plugging measures. Most traditional devices only rely on simple water retaining structure, which is difficult to tightly plug water inrush. When water inrush pressure changes slightly or water flow direction changes, water retaining structure is easy to have gap, leading to water inrush leakage, which cannot fundamentally solve the problem of water inrush.

[0004] Secondly, even if the traditional device plugs water inrush, it also faces difficulties in subsequent water pumping and drainage. Due to lack of reasonable water guide design, the effect and efficiency of water inrush emergency treatment are affected. INVENTION CONTENTS
