Jarek Jakubec and Dan Mackie
Friday, April 8, 2016
First presented: 
Cave Mining Forum - Workshop Series I

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 about mitigation strategies and mudrush risk assessments.
