Jarek Jakubec, has over 33 years of operating and consulting experience in Mining Industry. Jarek has been on operating mines in Canada, Botswana and Czech Republic. He has been involved in mining projects all over the world. He currently specializes in Technical auditing, Mass mining (open pit and caving), Diamond mining and Rock mechanics.
Jarek is considered cave mining expert and he was instrumental with Dr. Laubscher in development of rock mass classification system for caving mines. He also participated on several international research projects including MMT, Weak rock support and Best Practice for data collection. In association with Gemcom Software Jarek spearheaded development of new planning tool for Sublevel-caving Mines and he co-authored section for geotechnical data collection and interpretation for Large Open Pits (LOP) which become industry standard. He also held several cave mining lectures in Asia, Australia, Africa, South America and Canada and he is Qualified Person in terms of National Instrument 43 101.
Mudrush, mudflow, or mudpush are the most common terms describing uncontrolled ingress of assorted mixture of water and solids. Mudrush is the underground equivalent of surface debris flow. It can have different origins but produce the same results: injury, loss of life, damage to property, excess dilution, and production delays, or — in extreme cases

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

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
... 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

Continue reading.The welcoming note and introduction will briefly describe the concept and philosophy of the Cave Mining Forum which is primarily to connect professionals from the mining industry. Jarek will also provide a brief overview of the current cave mining world, past experiences and challenges. This presentation summarizes a talk given during the second workshop of
... Continue reading.This presentation will discuss the design criteria directly impacted by fragmentation in the cave mining setting. It will also highlight some of the current tools available for prediction and analysis of fragmentation, as well as the reliability and potential short comings of fragmentation prediction. This presentation summarizes a talk given during the second workshop of
... Continue reading.The industry perception is that sublevel caving is a “dirty mining method” (i.e. high dilution and low recovery). However, there were several successful sublevel cave mines executed in the past. The success of a sublevel cave mine is not by chance – they are engineered to perform. This talk will review some of the recent

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
