Main application.

This system is mainly applied to monitor the water pressure water leveltemperature of observation borehole water level of mine goaf surface water channelflow rate and remote control in real time in the underground coal mine and ground surface.
This system could be used for combined water test in mining area, forecast and early warning of water bursting zone in coal mine, petroleum and urban water supply, monitoring the pressure of the sealing wall, and the real-time observation of the pipe flow.

Main features.
Dynamic monitoring of combined waterproof test in mining area and analysis of regional hydraulic connectivity
Adopts multi-level warning to forecast water inrush disaster.
Having the advantages of easy installationmaintenance and operation, high precision and reliable performance. The bundled software able to generate data reportscurves and analysis of the historical data automatically.
Consisting of underground monitoring system and ground monitoring system, and unified management by the ground monitoring center station.
The system includes monitoring center, remote communication adapter, u data communication network (laying underground line or Ethernet networks) or GSM/GPRS wireless monitoring substation , data collection substation, measured sensor, mine explosion-proof power supply, etc.
