Erlihe Mine, Northwest Nonferrous Geological Exploration Bureau (NWNGEB)

Project type:

EPC general contracting of paste lining system with full tails

{&&-11}

Project description:

Due to regulatory requirements, Due to the long period of operation and the deepening of the works, the mine faced large ore losses and high tail disposal costs. FENY applied a cemented full-tail liner to fill the produced space, as well as a chamber development system with subsequent liner for deep horizons. Pulp concentration is about 70%, consumption — 80 m³ / h.

Project results:

The savings on environmental tax on the tails, construction and operation of the tail guard are 9.32 million yuan per year. Mineral resources are extracted to the maximum, the extraction rate is increased, resources are used efficiently and the service life of the mine is extended.
