With the continuous increase of coal mining depth, the geological conditions faced by underground fully mechanized mining operations become more and more complex, and the probability of water penetration during coal mining continues to increase. Mine flooding accidents have become an important factor in the safe production of dangerous coal mines, and real-time monitoring and early warning of mine flooding has become urgent.

At present, flood warning is mainly realized through three methods: hydrological detection and prevention, underground water exploration, and precursor phenomenon observation. Hydrological detection and downhole water exploration can prevent underground flood accidents. However, due to complex hydrological conditions, improper design, ineffective measures, poor management, and paralysis of people’s minds, hydrological detection and downhole water exploration cannot completely prevent water inrush. The occurrence of sudden underground water inrush can not be alarmed; the observation of aura phenomenon is mainly judged by human experience, and there are relatively large subjective factors. For the on-site water inrush accident, it mainly relies on the manual alarm of the on-site personnel. However, when the water inrush occurs in an unattended time or area, or when the on-site personnel flee in a hurry and fail to call the police, the dispatching room cannot timely obtain the water inrush that has occurred. It is impossible to notify the relevant underground staff in a timely manner, so that emergency measures cannot be taken in time for the water inrush accident, which may easily lead to out of control water damage and casualties.

The next day technology mine water level and flow monitoring system has the following functions:
