Minewater monitoring

Deep-sea probes performing key future tasks underground In collaboration with the Electrical Engineering and Information Technology research area at the THGA, the Research Institute of Post-Mining has been commissioned by RAG to use cutting-edge sensor technology to record the ascent of mine water in abandoned mineworks. To this end, a pilot system was installed at the former Auguste Victoria colliery in order to monitor the minewater ascent processes across the medium to long term. THGA’s experts have developed a measuring concept that enables them to determine the pressure, methane concentrations, flow rates and conductivity in abandoned mine workings over the longest feasible time period, and to determine the explosion protection requirements. For this purpose, we are using sensor technology more commonly found in deep sea applications, making it especially robust and durable. The FZN is also responsible for evaluating and interpreting the recorded data. Project objectives: Development and establishment of a suitable underground monitoring process for a planned underground minewater ascent in a decommissioned, closed and no-longer accessible mine installation Recording and documentation of appropriate measured values regarding the actual processes occurring within a mine during the controlled rise of the minewater In collaboration with the Electrical Engineering and Information Technology research area at the THGA, the Research Institute of Post-Mining has been commissioned by RAG to use cutting-edge sensor technology to record the ascent of mine water in abandoned mineworks.
