Problems solved by technology
The hydrogeological conditions in the mining area are complex, and generally contain multiple aquifers. The traditional groundwater level monitoring method requires high investment, high cost, and time-consuming monitoring, resulting in very few groundwater monitoring points in the actual mining area, and the water level monitoring holes are basically distributed in shallow outcrops. nearby, the resulting monitoring data cannot reflect the entire groundwater flow field

The invention discloses a mine ground drilling casing-free multi-aquifer underground water level monitoring system. The monitoring system comprises an underground detection module and an overground detection module, wherein the underground detection module is located in a monitoring hole, the underground detection module comprises a permeable layer and a water-resisting layer which are distributedalternately, the water-resisting layer is located at the bottom of the monitoring hole, the underground detection module comprises a sensor lead, at least two fiber bragg grating osmometers are arranged on the sensor lead, the fiber bragg grating osmometers detect the pressure of the permeable layer, and the overground detection module collects the pressure detected by the fiber bragg grating osmometers. The mine ground drilling casing-free multi-aquifer underground water level monitoring system is formed by combining the underground detection module and the overground detection module, so that dynamic monitoring of the underground water level of a multi-aquifer of a mine area is achieved, the investment cost is reduced, and the water level change of each low water flow field can be conveniently monitored.
Description
technical field [0001] The invention relates to the field of water level monitoring, in particular to a groundwater level monitoring system for mine ground boreholes without casings in multiple aquifers. Background technique [0002] Mine water level monitoring is of great significance to mining in this area. Traditional mine groundwater level monitoring requires casing to seal off the aquifer, and a single hole can only monitor the groundwater level of one aquifer. The hydrogeological conditions in the mining area are complex, and generally contain multiple aquifers. The traditional groundwater level monitoring method requires high investment, high cost, and time-consuming monitoring, resulting in very few groundwater monitoring points in the actual mining area, and the water level monitoring holes are basically distributed in shallow outcrops. Nearby, the monitoring data formed cannot reflect the entire groundwater flow field. Contents of the invention [0003] The pur...
