Long Distance Pumping Technology
Minova’s long distance pumping means a change in the way the miner works. Instead of small pumps or cans which constantly have to be supplied a long distance pump can be placed in the mine.
In general, long distance pumps are today installed centrally in the coalmine in order to supply entire mining fields from one location. If this is not reasonable, then the injection unit CT-PM is installed in the main or tailgate road of the coal face. The coal face is supplied by means of tubes and/or hose lines.
The pump can convey distances up to 5,000 meter and it is remotely operable. It is also electrically driven with radial piston technology and allows for an adjustable flow rate without pulsation.
The customer can choose between 2,000 or 600 liters resin containers depending on the expected injection requirement for the injection shift.
The long distance pumping system consists of 3 components:
- Long distance pump e.g. CT-PM
- Storage tank for each component serving as a reserve and supply tank for the pump
- Reusable containers
Introducing long distance pumping allows for an immediate initiation of measures for rock stabilization as the injection resin is available constantly.
The integration of this comfortable and efficient injection technology increases the value to the customer. It also increases productivity, secures production, reduces accidents due to falling rocks and reduces costs in transport, labor and maintenance. The implementation of long distance pumping improves safety and productivity in the mine.
Benefits of long distance pumping technology
- Increase and backup of the production by means of permanent availability of the injection resin with a high standard of quality
- Injection option during the extraction
- Reduction of transport costs
- Reduction of maintenance costs
- Reduction of personnel requirements
- Improvement of ergonomics and occupational safety
