This presentation will address a selection of papers delivered at recent conferences on the subject of hydraulic fracturing in cave mining. The focus will be on preconditioning with hydraulic fracturing and other applications of hydraulic fracturing in cave mining. This presentation summarizes a talk given during the second workshop of the Cave Mining Forum.... Continue reading.
This presentation will discuss the design criteria directly impacted by fragmentation in the cave mining setting. It will also highlight some of the current tools available for prediction and analysis of fragmentation, as well as the reliability and potential short comings of fragmentation prediction. This presentation summarizes a talk given during the second workshop of... Continue reading.
The industry perception is that sublevel caving is a “dirty mining method” (i.e. high dilution and low recovery). However, there were several successful sublevel cave mines executed in the past. The success of a sublevel cave mine is not by chance – they are engineered to perform. This talk will review some of the recent... Continue reading.
The presentation will explain the benefits of a fully flexible, macro-driven cashflow model to rapidly assemble, evaluate, and rank strategic options in complex cave mines. The model allows for multiple production schedules across multiple caves (typically produced from PCBC) to be re-scheduled and assembled into coherent strategies and compared across a range of evaluation parameters....

Recent improvements to PCBC and PCSLC are discussed. The trend for software development as well as some ideas for the future integration of PCBC and PCSLC into the Dassault Systemes software solutions will be outlined. Key areas are around daily operations management and improved 3D flow modeling.... Continue reading.
This presentation will provide a brief overview of automation in the mining industry; in particular, its application to cave mining. Mine automation becomes more popular as it improves safety and eases fleet utilization and production rates. It can also reduce maintenance and operating costs. However, the implementation of mine automation requires full analysis of its... Continue reading.
For caving studies, the approach to geotechnical characterization differs from other mining methods and must address a number of cave-specific design aspects; those include: caveability, fragmentation, draw point spacing, draw strategy, subsidence, analysis, and ground support. Risk of mudrush, airblast, and rockburst has to be also evaluated. This discussion will provide a brief discussion of... Continue reading.
This presentation summarizes a talk given during the inaugural workshop of the Cave Mining Forum. This presentation will highlight one of the cave mining phenomenon related to surface and ground water. Water combined with clays and fine particles generated by caving processes could result in mudrushes and mudflows. This presentation will also include the discussion... Continue reading.
This presentation summarizes a talk given during the inaugural workshop of the Cave Mining Forum. This presentation will briefly discuss how cave mine closures can differ from typical underground mine closures. There is limited experience to closing cave mines so there are more questions than answers; however, it seems clear that wet climate closures, in... Continue reading.
