Risk assessment and treatment plan analysis of confined water in coal seam floor of mines
The problem of underground water inrush in coal mines not only interferes with normal mining operations and mining efficiency,but also increases the investment in coal mine safety engineering,and can even lead to serious coal mine water seepage accidents,seriously threatening the personal safety of coal mining personnel.This study takes a certain coal mine in China as an example to analyze and evaluate the risk of water inrush from the mining face,and uses comprehensive detection,drainage and pressure reduction,and grouting reinforcement technology to treat the problem of pressurized water in the coal seam floor of the mine,achieving good prevention and control effects.
