Keeping up with caving, BLOCK ANd pANeL CAVING Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping orebodies located at depth, particularly those with disseminated mineralisation or that are low-grade in nature, but too deep to be extracted using open pit methods Block caving also depends on insitu stresses andFull scale near field flow behaviour at the Ridgeway Deeps ,, Full scale marker experiments were designed and implemented at the Ridgeway Deeps block cave mine from March 2008 to October 2010 The experiments aimed at quantifying and assessing the geometry of the extraction zone, development of the extraction zone over time, variability of flow behaviour, and factors affecting flow behaviour in both the near and far field of the cave columnKey geotechnical knowledge and practical mine planning ,, of the Ridgeway sublevel cave The success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations What makes Cadia unique is the high-stress, hard rock mining conditions combined with the ability toDraw Control Optimisation along the Production Drift in ,, The amount of material extracted from each blasted ring in sublevel caving mines is vital when deciding the overall mine production target The orientation of the production drifts is normally perpendicular to the strike of the orebody, and rings are blasted from the hanging wall side to the footwall side in a ,Darda C12 Hydraulic Splitter from Kennards Concrete Care ,, Stephen Duffield said that the Ridgeway Deeps mine will use the block caving technique to extract the gold and copper bearing ore He also says that it is a cost-effective way to mine, using ,.

Design rules for avoiding draw horizon damage in deep ,, damage in deep level block caves by RJ Butcher* Synopsis Deep level block caving as a mining method is becoming more popular due to the fact that it is the lowest cost per ton underground extraction system However, many block caves do not achieve their full potential due to ,Block caving, Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining The technique is commonly used to extract low grade copper, copper-gold, iron and molybdenum ores although ,
