煤矿底板突水事故及防治措施的研究

Study on Water Inrush Accident from Coal Mine Floor and its Prevention Measures

针对煤矿底板突水问题,通过分析底板突水事故原因,提出了煤矿底板突水事故的防治措施,具体研究了注浆堵水方案的实施,并进行了实践应用。应用结果表明,实施注浆堵水的措施之后,各含水层水压比突水后提高了1.3 MPa。工作面的出水量得到显著降低,含水层的水压也已经接近了在正常水位,底板突水问题得到有效治理。

In view of the problem of water inrush from coal mine floor,through analyzing the causes of water inrush from coal mine floor,this paper puts forward prevention measures for water inrush from coal mine floor,specifically studies the implementation of grouting water plugging scheme,and makes practical application.The application results show that the water pressure of each aquifer is 1.3 MPa higher than that after water inrush after the implementation of grouting water plugging measures.The water output of the working face has been significantly reduced,the water pressure of the aquifer has also been close to the normal water level,and the water inrush from the floor has been effectively treated.
