Rock strata heat in time-dependent underground heat modelling
The paper presents a method to solve for the rock strata radial heat conduction across all the airways of a mine ventilation model. The method allows the investigation of a range of time-varying heat phenomena in underground...
Fog control and prevention in underground mine travelways using refrigeration
Fog formation in underground mines can cause poor visibility in travel ways, accelerate corrosion of ground support and steel infrastructure, and damage electrical and electronic devices continually exposed to moisture. Fog in mines...
Empirical analysis of fire-induced pressures for mine-wide emergency response planning
Emergency response planning is an integral part of any modern mine’s engineering workload. Potential underground fires and personnel evacuation as well as rescue teams’ response algorithms must be considered. The Ventsim...
Efficient and accurate ventilation surveys for model calibration
The increasing use of ventilation simulation software since the 1990s has changed the work of ventilation professionals, decreasing the requirement to do manual calculations and computations. Ventilation simulation software…
Reconsidering the Wetness Fraction in Geothermal Heat Transfer Modelling
The study reviews the current practice in underground mine heat modelling of distributing geothermal heat between its sensible and latent components. A commonly used technique is to define an equivalent wetness fraction…
Agnew Gold Mine Expansion – Mine Ventilation Evaluation using Ventsim
The Redeemer Gold Mine is a sub-level caving gold operation located in Western Australia. The underground mining commenced in 1989 and followed a slightly subvertical ore body to the depth of approximately…
Fire Modelling in Underground Mines using Ventsim Visual VentFIRE Software
The risk from fire remains one of the most serious of underground mine disaster scenarios. The impacts of mine fires on the underground ventilation system and the production of toxic gases have been difficult to model…
Life of Mine Ventilation Requirements for Bronzewing Mine using Ventsim
Bronzewing Mine is located in the centre of the Yandal Belt, 360 km north of Kalgoorlie in Western Australia. Discovered in 1992 by Great Central Mines, the Bronzewing Mine is now owned and operated by…
Practical prediction of blast fume clearance and workplace re-entry times in development headings
Re-entry into blast fume affected underground areas is a safety and productivity concern for most mines. Lengthy re-entry times may improve clearance of noxious gases, but can result in production delays and decreased…
Underground Fire Rollback Simulation in Large Scale Ventilation Models
Fire in an underground mine poses a serious threat to health and safety of personnel due to the spread of heat, smoke and noxious gases throughout the ventilation system. Predicting the behavior and likely spread of combustion…
Quality Assurance Standards for Mine Ventilation Models and Ventilation Planning
Most mine ventilation engineers are involved in ventilation planning and design in some capacity. Ventilation modelling software used by a competent experienced ventilation engineer is extremely…
Diurnal Thermal Flywheel Influence on Ventilation Temperatures in Large Underground Mines
The daily temperature variance between daytime and night-time can have a significant influence on the ventilation conditions within a mine. Air temperature variations are reduced as air travels further into a mine due to the storage and release of heat in rock boundaries and variations in heat transfer between...
Emergency Egress Pathway Prediction Using Ventilation Models
Mine ventilation models are now an accepted component of most mine management systems. However, modern ventilation models also represent a highly structured spatial data source, defining underground pathways and connections across a mine...
Improving the Performance of the Hardy Cross Algorithim for Large Ventilation Models
The Hardy Cross algorithm offers a reliable method of solving network systems of fluid flow and has become widely used for solving water and ventilation flow networks. A limitation is that computational iterations and time to solve a network rises rapidly ...
Predictive Network Modelling with Live Sensor Data
Advanced fibre-optic based sensing systems are fast growing and replacing conventional sensors in many industries due to their reliable measurements, fast response, and intrinsically safe operations. The deployment of any sensor system however remains a potentially expense and disruptive activity...
Use of Live Sensor Data in Transient Simulations of Mine Ventilation Models
The implementation of sensor systems to monitor mine ventilation atmospheres offers numerous safety and operational benefits to mines. Detection of dangerous gases, changes to airflows and temperature, and detection of clearance of fumes or contaminants are some of the obvious benefits of using atmospheric sensors in mines...
