In general, automation is most effectively applied to repetitive tasks, such as production loading and trucking. The significant presence of these highly repetitive tasks in a cave mining environment make automation particularly attractive. The increasing automation of mining equipment is the natural evolution of basic tele-remote operation. The primary benefit of tele-remote mining is in... Continue reading.
In 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. Post-drilling assessment is the process of mitigating this risk by verifying that blastholes have been drilled accurately with the correct length and orientation, following the blast design. Although... Continue reading.
A geotechnical model is the fundamental basis for the design of an open-pit and underground mines. A fully understood and representative geotechnical model provides information on the engineering characteristics of the rock mass, defining how it will behave during excavation. The model’s individual domains, each comprised of materials exhibiting internally similar geotechnical properties, reveal the... Continue reading.
SRK 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. The goal was to provide production continuity at a rate that will still be suitable to maximise use of the... Continue reading.
In 2000, International Caving Study (ICS) published a practical manual on block caving by Dr. Dennis Laubscher. This first comprehensive block caving publication was co-authored by several industry experts, including Dr. Alan Guest and Jarek Jakubec of SRK Consulting (Canada) Inc. Unfortunately, the distribution of this publication was not widely available. Meanwhile, the demand for... Continue reading.
Mass 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. Diamonds have only been mined on an industrial scale within the past 150 years, mainly as open pit mines. Underground mining of those deposits was first implemented within the second half...

The 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. CODELCO is currently finishing the detailed engineering stage and constructing the main infrastructure for the project. The underground mine is expected to... Continue reading.
It is important in an industry such as cave mining to keep up-to-date knowledge, experience and best practice at the forefront to maintain the best possible level of safety for all involved. Unfortunately, much knowledge is proprietary to commercial research project sponsors. The Australian Centre for Geomechanics Caving 2018 Symposium, with Collaborating Organisation SRK Consulting...

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... Continue reading.
This presentation summarizes a talk given during the inaugural workshop of the Cave Mining Forum. This presentation will briefly discuss how cave mine closures can differ from typical underground mine closures. There is limited experience to closing cave mines so there are more questions than answers; however, it seems clear that wet climate closures, in... Continue reading.
