Strata Behaviors of Fully-Mechanized Sublevel Caving Face

in view of research situations of the fully mechanized sublevel caving, the similar simulation test model for fully mechanized sublevel caving was presented. During the top-coal caving process, variation of top-coal subsidence and abutment pressure were measured.

Latin American Mine Uses Microseismic to Mitigate Risks

from sublevel stoping to sublevel caving. This mining method is meant to boost productivity but can also introduce new challenges. A microseismic monitoring solution was specified to help identify potential hazard areas, observe microseismicity patterns and obtain a full three-dimensional image of the caving front development in real time.

Mining-induced ground deformations itasca.se

Mining using sublevel caving is cost-efficient and allows a high degree of mechanization and automation. The method relies on caving of the hangingwall rock, which has the un- fortunate side-effect that the ground surface on the hangingwall side continuously deforms as a result of mining.

Cave mining 16 years after Laubscher's 1994 paper 'Cave

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'.
