Cave mining: 16 years after Laubscher's 1994 paper
2013-11-29 Abstract. This paper supplements a keynote address prepared for the 2010 Second International Symposium on Block and Sublevel Caving. The author gauges the cave mining industry's position (practice and theory) since the publication of what he considers a seminal paper on 'Cave mining – state of the art', hence '16 years after'.
