Mine planners utilize production schedules to determine when activities should be executed, e.g., blocks of ore should be extracted; a medium-term schedule maximizes net present value associated with activity execution while a short-term schedule reacts to unforeseen events. Both types of schedules conform to spatial precedence and …

The first step to creating a fool-proof mine safety system is knowing these hazards and their gravity. Cave-ins and Roof Falls – In underground mining, large hollow pits, rooms, and tunnels are created to remove rock and dirt before conveying people and equipment. It is a serious concern because the structure could collapse, trapping the ...

The evaluation index system of the security of a mine ventilation system was studied, and the security was described quantitatively in the safety degree. A mine ventilation system has a deterministic function for the safety of coal production and for the control of mine accidents. So, it has an important meaning to evaluate the security of a mine …

The existing mine ventilation system was already at capacity (220 m 3 /s) due to a combination of the limitations of the intake ramp (29.4 m 2 ), the small size of the sole

The current risk management and assessment systems being used in the South African mining industry prove not to be adequate to stop people from losing lives underground. What is missing from the currently used systems is a comprehensive and integrated

1. Introduction. Mining is a hazardous occupation, accounting for 1% of the global workforce and 8% of fatal occupational accidents, with more people employed in artisanal and small-scale mining (ASM) than large-scale mining (LSM) [].In Zimbabwe, the zero-harm policy [] targets the formal sector, which includes LSM and excludes the …

Primary ventilation solution to support the Sepon underground mine operations. Our client operates one of the largest Gold and Copper Mines in Laos PDR, located in the Savannakhet Province. To enhance the mine's ventilation system, the client required a comprehensive solution that included surface-mounted primary fans and advanced …

This incremental approach to ventilation on demand is proving to be easier to implement than a whole-of-mine ventilation-on-demand system and is applicable to smaller underground mining operations. IVOD drives significant energy and cost savings; as these savings are realised by the operator they can be used to expand ventilation-on-demand ...

Video surveillance in mine security. Security requirements differ by the mine type. Open-pit mines are based on authority and risk levels and put emphasis on access control, while underground mines — …

Our ventilation analysis also indicated fan operating points needed at various stages in the mine cycle plus other ventilation modifications to enhance the system. We proposed initially installing an interim booster fan to push air up from 24 Level to the main exhaust shaft and later replacing the main surface fans with a single, larger exhaust ...
