Very few actual ODS events occur because of critical safety events.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Often these ODS events are false negatives caused by:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Slight ground condition rutting<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Water pooling from rain or excessive watering<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Excessive dust<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mechanical component failures<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Even Sun glare\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Every time an AHT has one of these ODS events it must be physically attended by a member of the pit operations team, even if it is one of the numerous false negatives. Obviously, this is a time-consuming manual process that needs to be avoided in the first place. Often in a new AHS operation these events can number over 120 per shift.<\/span><\/p>\n<table>\n<tbody>\n<tr>\n<td>\n<h3><b>The best way an AHS mine can reduce ODS events in the first place is to have well maintained and designed haul roads that better suit AHS operating requirements. Using the right tool for the job when it comes to dust suppression is imperative.<\/b><\/h3>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"font-weight: 400;\">With the early continuing development of Caterpillar and Komatsu Autonomous mining water trucks beginning to gain traction with their products one of the biggest challenges has always been how to best get the dust suppression medium applied correctly and accurately, until now it has always been a manual process performed with less than optimum equipment which is then left to the individual water truck operator&#8217;s discretion to determine application areas and volumes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Global Road Technology (GRT) Haul-Loc Dust Control System is uniquely positioned to compliment the use of AHS by incorporating into a more data-driven dust suppression application system rather than the traditional individual operator manual approach which leaves huge inconsistences in accuracy and hence results. Autonomous water trucks will reduce volume by only applying the substance to desired areas of the pit when required, and as environmental conditions change during the shift the requirement to have a water truck operating unnecessarily can be much easier managed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Simply put AHS works best when interactions are kept to a bare minimum. One of the biggest contributors to these interactions are the water trucks. By using more technologically advanced dust suppression techniques and products this not only reduces troublesome, unwanted interactions in the pit, but also greatly reduces the lost operating time from false positive ODS events.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can already easily see the compounding benefits GRT\u2019s Haul-Loc and <a href=\"https:\/\/globalroadtechnology.com\/\/smart-dosing-units\/\">SMART Dosing systems<\/a> can have on an AHS mine sites operating model.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Improved dust suppression products and techniques incorporated with autonomous mechanical applications is a win in every column.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">AHS has come a long way in the last 15 years, now it is time some of the other associated operating practices begin to develop, improve, and refine. Automated dust suppression has a huge advantage in this area as it has multiple positive outcomes for mining safety and productivity.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As environmental considerations and the availability to water become increasingly scarce in many mining regions of the world, improved dust suppression products and techniques are the next logical step in the progression of an automated mining operation.<\/span><\/p>\n<p><b>Your feedback is important to us.\u00a0<\/b><\/p>\n<p>Your feedback is important to us.
