COLLISION AWARENESS & AVOIDANCE enabled models. “Our data logging capacity is able to capture all information relating to the interactions between the pedestrians and the vehicles, and also between vehicles themselves,” he says. “This provides the mine with a ‘road map’ to track how any incident occurs, making it easier to report The Booyco Electronics proximity detection system incorporates the latest technology to ensure compliance Booyco Electronics’ PDS can facilitate such collision avoidance, with automatic slow-down and even safe-stop of mining machines. The system uses VLF antennae on a vehicle to create fields within a danger zone around the vehicle. The size of each field can be determined by the customer, to suit their specific operating environment and addressing identified risk. An RFID tag installed on the pedestrian’s cap lamp alerts them – through a light and sound alarm – when they enter this zone. The light changes colour from green to orange and then red, the closer the pedestrian is to the vehicle. The vehicle itself also receives a warning from the PDS, with the operator being alerted that a pedestrian is in the proximity. If equipped and configured appropriately, the vehicle can also be automatically slowed down at a certain distance from the pedestrian, and similarly brought to a safe stop. One of the most significant advantages of the Booyco Electronics PDS is that it can effectively detect as many as seven TMMs and 20 pedestrians within one field, in the underground environment. “Our technology prioritises the safety of the pedestrian in mines, whether underground or and to improve practices.” The Booyco Electronics Asset Management System (BEAMS) gives mines the ability to extract useful data on risk areas. This can feed into focused training of staff for more effective safety behaviour. With 13 years of experience in PDS, Booyco Electronics has supplied in excess of 5,000 sets of mining vehicle equipment around southern Africa, as well as 50,000 pedestrian sets of equipment. Schauenburg: innovation that saves Schauenburg Systems, part of the Schauenburg international group of companies, is a South- African OEM of MIMACS (Mine-wide Integrated Monitoring and Control System) that addresses multiple safety concerns within the underground and surface mining discipline. The company told IM: “We are a solution orientated organisation and have been a stakeholder of ‘supplying and implementing solutions’ with many large mining houses since 1972. Where solutions are not available and an applicable business case exists, we usually apply our experience and current solutions available to tailor make a fit for opencast,” says Janse van Rensburg. “Our mission is to save lives, and to ensure that every worker returns home safely every day.” The company’s market leading systems are intrinsically safe, working on a clean 12 Volt power supply that will not ignite methane gas or coal dust. Customers value the complete turnkey solution that Booyco Electronics can provide, says Janse van Rensburg. “Our combined technology includes a very low frequency (VLF) signal that penetrates rock walls underground,” he says. “This ensures that the pedestrian will still be warned of an approaching vehicle even if it is out of sight around a corner.” The PDS can be applied to older ‘non- intelligent’ machines on a mine as well as the newer, controller area network (CAN) bus International Mining | JANUARY 2020 Overview of Schauenburg SCAS for Underground purpose solution.” Ettiene Pretorius, ESS Business Unit Manager at the company states: “Manufactured, distributed and supported by Schauenburg Systems in South Africa, we have supplied over 3,000 vehicle systems and over 40,000 pedestrian tags already. The SCAS Collision Avoidance System is modular in design and engineered to be a building block of MIMACS – a smart software system assisting the mine with its digitisation process where the first edition systems were launched as early as 2005. Designed for surface and underground trackless and track-bound machinery, this system can be configured to accommodate different functionalities to enhance safety.” Providing early perimeter warning notification can give vehicle operators and pedestrians a head start in deciding how to manoeuvre during or before the critical decision making period. The SCAS Collision Avoidance System uses dual band RF Technology including GPS and Artificial Intelligence object detection technology for surface and underground to warn a vehicle operator that a vehicle, pedestrian and/or a fixed hazard are detected in configurable warning zones. The system also indicates the orientation of the potential hazard around a vehicle. The system is designed and tested to comply to the latest ISO21815 draft protocol in order to provide the necessary PDS interface signals to safely slowdown or stop a vehicle during an identified risk situation. Other rolled out features include real time location monitoring, page message communication system, on-board gas detection & interlocking, an asset management & control system and interfacing with Schauenburg’s Intellisens handheld multi-gas detection system.
