Geology Consolidation and Ventilation and Ventilation Control Devices in Underground Mines: Determination of Design, Monitoring and Safety Standards

M Salu Parsons Brinkerhoff ABSTRACT: While hazards resulting from spontaneous heating, gas migration, explosions and flooding remain a major threat to the safety and productivity of underground mines, specific research into overpressure ratings and integrity testing of ventilation control devices (VCDs), bulkheads and dams remains relatively limited. Given the difficulty to conduct field tests in operational environments, as well as the high variability of mine ventilation and geology conditions, the performance of ventilation control devices poses a significant challenge for underground mines. In Australian studies, a computational engineering model has been developed to determine overpressure-rating standards for ventilation control and

Water-Retaining Bulkhead Design For Water Ingress Management

Recent incidents of water inrush at underground mines in Queensland and New South Wales have underscored the role of engineered water-retaining bulkheads and dam walls as part of a water management plan. As underground mines across Australia recover from the impact of recent rainfall and subsequent flood levels, safety authorities are now warning mine operators to consider the potential impact of water ingress from surface accumulations, directly or via aquifers, in volumes not experienced before. While recommended water management strategies include the installation of water-retaining bulkheads and dam walls, a range of variables needs to be considered to determine the

Aquacrete Upgrades Wa Manufacturing Plant

Aquacrete is set for further growth in the mining and civil sectors following the completion of a significant stage in the improvement project at its Western Australian manufacturing plant. Aimed at maximising plant efficiencies whilst ensuring stringent product quality management, the project has included a plant-wide electrical upgrade as well as the introduction of new fans and an additional automated batching plant. The construction of a new workshop will facilitate on-site fabrication and maintenance to further reduce plant downtimes, while extensions to the site’s main storage area will enhance the company’s product processing efficiency. “This is an exciting step for

Aquacrete Supports Earth Hour

On 26 March 2011, Aquacrete will join hundreds of millions of people across the planet in support of Earth Hour, the internationally recognized climate change awareness initiative. Earth Hour began in Sydney in 2007 and has become a worldwide event across 128 countries and over 4600 cities, with people and businesses switching off their electricity for an hour each year to pledge their support for the planet. Aquacrete will demonstrate its support of the global ‘switch off’ by turning off non-operational lighting, equipment and plug points at its operations across Australia for Earth Hour. This year, in addition to Earth
