There are over 50 global cave mining projects in various stages of studies and development.
Learn MoreIn 2001, Laubscher’s Mining Rock Mass Rating (MRMR) classification system (Laubscher and Jakubec, 2001) introduced the rock block strength concept to account for scale effects and the influence of closed defects on intact rock strength (IRS).
Learn MoreRecently, SRK Chile was involved in a caving project in Chile and in charge of numerical modelling to analyse pillars and overall mine stability and to define ground support.
Learn MoreA geotechnical model is the fundamental basis for the design of an open-pit and underground mines.
Learn MoreSince the 1990s, ‘mine-to-mill’ studies have evaluated the impact of blast fragmentation on downstream plant throughput.
Learn MoreSRK performed a comprehensive redevelopment of the geotechnical model for an existing large panel caving operation with the aim of assisting cave planning and design in five future cave blocks.
Learn MoreThe Chuquicamata underground mine in the Atacama Desert in northern Chile is one of the largest planned mining projects in the world to use block caving with macro-blocks option to mine copper ore.
Learn MoreMass mining including block caving, incline caving, front caving, sub-level caving and sub-level retreat are the principal mining methods for primary diamond deposits worldwide.
Learn MoreIn 2000, International Caving Study (ICS) published a practical manual on block caving by Dr. Dennis Laubscher.
Learn MoreSRK carried out a scoping study on an existing open pit operation (12 Mtpa) that is soon to be reaching a depth where the mine will need to transition to a large-scale underground mining method.
Learn MoreMany ore deposits extend vertically, a fact which is not always known at the start of mining.
Learn MoreFor early stage caving projects, there is usually a high degree of uncertainty in the input parameters that impact the mine design and strategy.
Learn MoreCave mining, and in particular block-cave mining, stands at one end of the spectrum of mining method-related risks.
Learn MoreMudrush, mudflow, or mudpush are the most common terms describing uncontrolled ingress of assorted mixture of water and solids.
Learn MoreIn sublevel caving operations, it is imperative that the production blastholes be drilled accurately so that there is no risk of unblasted ore remaining between adjacent drawpoints.
Learn MoreIn general, automation is most effectively applied to repetitive tasks, such as production loading and trucking.
