The chart above shows an average of 1,818 additional tonnes per first hour, representing a 21% increase in production for the month of March 2015, compared to December 2014.
“Leica Jigsaw presented the strongest technical offering, with its flexible and robust software all supported with remote problem solving,” said Rodriguez. A flexible user-permits policy also helped, said Rodriguez. The base license permits access to all users onsite.
“Although various people see the reports, and many departments contribute information, licenses were not needed for everyone so this was a benefit,” he said.
“So, as far as navigational systems, Leica Jigsaw products are the leader in the field. Therefore, the solutions for the satellite navigation in the high-precision products are the most advanced in the market. This was a decisive part for us,” said Rodriguez.
The system installation included a room for the dispatch in the highest part of the mine. This offered a full view of mine operations via visual controls. Three 52-inch screens were installed to display different dashboard views of the mine. Each dispatcher was supplied with three additional 32-inch screen displays. The smaller screens manage the roads on Jview and allow for real-time reports. The other dispatcher handles control of the operation and production equipment, including loaders and trucks.
Now CDM has designated maintenance dispatchers equipped with the proper notification systems, preventing maintenance issues from draining time and resources. Operators needing support or experiencing problems with equipment can speak directly with maintenance or text messages from the system, thus reducing radio frequency demands.
CDM enjoys numerous benefits from Leica Jigsaw. The primary crusher is now monitored in real time. Any delay generates an immediate alert, avoiding the need for phone calls or radios, which can sometimes be unreliable. Individual dumps in the crusher, waste, leach pads, and stockpiles are monitored and reported on. With multiple destinations, every truck is unloading exactly where and when it needs to be.
“Prior to partnering with Hexagon Mining Operations, it had been extremely difficult for us to achieve precision in our extraction, given the size of our equipment,” said Rodriguez. “Since the implementation, significant improvements have been achieved in our ore control, as can be seen in our current production increases.”
Daily plans can also be visualized via a quality tracker in each loader. Short-term planners load the plan in 12-hour increments so loading machines display their hauling requirements. This is a significant improvement on the old process, which involved marking surveyors with flags – flags that would sometimes be washed out in the rain.
“The solution provides reliable and flexible and automatic reporting, for production, productivity, availability, drilling information, and many other aspects of the mine operation,” said Rodriguez. The chart below shows an increase of 19,963 tonnes from July 2014 to August 2014, representing a 9% increase in overall production.
