The heat load and cooling requirements in deep mines will be significantly higher than in most shallow existing mines. Mines implement ventilation and cooling systems and controls to provide a conducive working environment. In the South African mining industry, the crucial focus has often been on heat stress management because as mines …
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 …

A diagonal mine ventilation system configuration was recommended based on the results of the network modeling exercise of the various options. ... An investigation into the application of ventilation on demand system at Gwalia Gold mine was conducted to better understand the mechanics of the system, and help identify what style of system ...
Several site visits were conducted to audit the ventilation system in order to both identify possible system improvements and to increase efficiency. A series of time-phased network ventilation models were developed to …
Modern ventilation systems employ a network of shafts, raises and adits, combined with ventilation fans and regulators, which distributes airflow through the mine to dilute and remove hazardous …
This paper deals with the problem of ventilation in underground mines, especially in diagonal systems, and the importance of regulating ventilation to provide the required …
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
Integrated security systems; Video surveillance and process monitoring; Advanced video analytics; Video and imaging management systems; Intrusion detection; Access control; Integration with other systems, such as fire and emergency; The implementation of a mine security solution follows several steps and depends on the …
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 ...
The WorkSafe Mines Safety inspectorate is reminding mine operators that all mines must have a deployed and functioning mine safety management system (MSMS) by 31 March 2024, after finding that many mines had failed to properly develop or implement an MSMS. All mines were required to have a fully-developed MSMS by 31 …
Security controls, as shown in figure 2 and Table 1. SECURITY MANAGEMENT: Security Management is the identification of an organization's assets ( including people, buildings, machines, systems and information assets) followed by the development, documentation, and implementation of policies and procedures for protecting assets (ASIS, 1997).
Fansare used to facilitate airflow control, and for effective application in monitoring and control systems; they should be equipped with either a variable frequency drive (VFD) or an in-flight blade pitch adjustment (BPA). Regulators/Louversare physically adjusted to control the …
Adding control strategies to an underground mine ventilation system is a viable solution for reducing operating costs, providing additional insight into the system and increasing health and safety benefits by eliminating hazardous contaminants and knowing where personnel are located using telemetry.
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 …
The mine layout evolves as decline and drives are developed, necessitating sophisticated ventilation systems designed by experts. These systems are often modelled using specialized ventilation modelling tools. Traditional Ventilation Challenges and Costs. ... Consider a gold mine aiming to reduce its AISC: Implementing VOD in key working …
Over the past seven years, he has taught mine ventilation courses at the Universities of Oviedo and Cantabria in Spain and at ESPOL in Ecuador. He is currently an Assistant Professor of Mining Methods at the University of León (Spain). He has co-authored more than 30 research articles on environmental engineering and mining engineering.
The thermal management system of deep mines is a complex and huge topology network. The change of a certain operating condition will cause an unpredictable behavior of system, which aggravates the control difficulty. This paper proposes a thermal management system for the deep gold mine, which fully utilizes the existing cycle air …
