A review of local and international heat stress indices, standards and limits with reference to ultra-deep mining In order to plan effectively for ultra-deep mining (UDM) projects, a number of issues must be addressed, not the least of which is the provision of workplace environmental conditions that are conducive to safe and productive mining operations.

 · Kidd Creek Mine is an ultra-deep mine in northern Ontario, Canada. We mine metal, copper, zinc, silver, and it''s one of the deepest in the world. It features large openings that need to be inspected on a regular basis. When it comes to this type of mining, the most ...

 · But the big question remains: how do they do that while navigating the safety challenges posed by ultra-deep mining? "It''s pretty clear to us that the seismicity that we''ll encounter down there will be a big step change from where we are," said Michael MacFarlane, Glencore SINO''s innovation consultant, during the April 14 2021 Virtual Mining Health and Safety Conference hosted by ...

SUDBURY, ON – The Ultra-Deep Mining Network (UDMN) held its second annual Symposium for its 76 network members from across Canada and […]

Abstract As depth of mining increases, so the production costs of the aurifereous Witwatersrand deposits are continuously increasing, with some mines already mining at depths exceeding 3500 m. Health and safety aspects are, simultaneously, gaining in importance. Therefore, in order to mine deep orebodies in existing mines, as well as to develop new mining ventures safely and efficiently, novel ...

 · "Mines are extending and digging deeper, and are therefore reliant on water transfer systems, which can handle the greater pressures at these deeper depths," Steverlynck tells Australian Mining.

 · It also addresses some technical geomechanical issues associated with deep mining. Some of the current challenges, advances, and prospective issues in deep mining can be summarized as follows: (1) Deep mining will become common in the future as coal and mineral resources at shallow depths gradually become exhausted.

The 40% Mine; Improve the energy consumption profile of deep mines. The Challenge: The 40% Mine is an initiative that aims to reduce the energy consumed by mines to 40% of their current consumption levels by 2040. This theme of the UDMN will work toward this goal specifically for Ultra Deep Mines. The energy required to power underground mine ...

This study reviews the concept of squeezing (large time-dependent deformation) in rock and investigates the possibility of this phenomenon becoming more pronounced in the planned ultra-deep mines of the South African gold mining industry. Although squeezing behaviour is not commonly found at the current depths of the gold mining industry, it is observed at Hartebeestfontein Mine due to a ...
