For underground mine, the current usual technique for ore extraction is block caving, which generates and induces seismic activity in the mine. To understand block caving method is one of the most challenging problems in underground mining. This method relies on gravity to break and transport large amounts of ore and waste. The state of art in dama...

  • Dec 2020
Block caving is an ore extraction technique used in the copper mines of Chile. It uses gravity to ease the breaking of rocks, and to facilitate the extraction from the mine of the resulting mixture of ore and waste. To simulate this extraction process numerically and better understand its impact on the mine environment, we study 3 variational model...

Conference Paper
  • Jan 2020
Worldwide the mining activity is facing lower grades, deeper ore bodies and stronger stresses within increasing massive operations. These challenges have several technical difficulties, uncertainties and associated systemic risks, which can affect the business survival and the long-term sustainability of the operation. For underground mine, the cur...
