Modern Quarrying Q1 2024

human involvement. This reduces workers’ exposure to hazardous environments, such as confined spaces and noise pollution. The system employs intelligent algorithms, combined with sensors, to identify blockages and initiate the unblocking process without human intervention. This ground breaking technology not only improves productivity and reduces downtime but also enhances the safety of quarrying operations by minimising the need for manual intervention in hazardous situations. Efficiently separating materials while prioritising worker safety Screening is a critical process in quarrying that separates materials based on size, allowing the extraction of specific aggregate fractions. As with crushing, advancements in screening techniques have led to enhanced safety measures. Innovative sizing methods Sizing materials in quarrying operations is essential to meet specific requirements for construction projects. Traditionally, this process involved manual handling of heavy machinery and increased the risk of accidents and injuries. However, innovative sizing methods are transforming this aspect of quarrying, improving safety and efficiency. Modern sizing techniques leverage advanced technologies like laser scanning, 3D modelling, and computer simulations. These tools enable accurate measurements and precise sizing without the need for workers to physically interact with the machinery. By minimising manual intervention, these methods significantly reduce the risk of accidents and create a safer working environment for quarrying personnel. technology is playing a pivotal role in transforming health and safety practices and revolutionising the handling of challenging materials. Technidrive’s crusher unblock system stands as a shining example of innovation within the quarrying industry. l As the quarrying industry progresses into a new era,

CRUSHING AND SCREENING

The quarrying industry plays a crucial role in the extraction of valuable minerals and materials for construction and infrastructure projects. However, the handling of challenging materials in quarries has always posed risks and obstacles to workers’ safety. David Strain Technical Director at systems integrator Technidrive, tells Modern Quarrying how technological advancements have revolutionised the way materials are crushed, screened, and sized in quarrying operations, significantly enhancing safety measures. ADVANCEMENTS IN CRUSHING, SCREENING, AND SIZING FOR ENHANCED QUARRYING SAFETY

F rom hand-arm vibration and falls from heights, to explosives and heavy machinery, quarrying workers may be exposed to a number of health and safety risks due to the hazards typically found in quarries. Automation has long played a pivotal role in enhancing safety in quarrying operations. Machinery equipped with automation systems can perform tasks that were previously executed by manual labour, eliminating the need for workers to enter hazardous areas. Intelligent crushing systems One of the most significant advancements in quarrying technology is the introduction of automated crushing systems. Crushing is an integral process, where large rocks and aggregates

are broken down into smaller, more manageable sizes. Traditionally, this task involved heavy machinery and manual labour, which posed significant safety risks. Crusher blockages in particular can be highly hazardous and can lead to costly downtime. To unblock a crusher a plant must usually be shut down and the system must first be isolated. Despite these precautions, a crusher can still be a serious risk to personnel due to the material which can be suspended in the crusher chamber. In response, modern crushing technologies have brought about remarkable improvements in safety and automation plays a pivotal role here. Advanced control systems and sensors are employed to monitor and adjust crushing parameters, ensuring optimal performance while minimising
