JULY 2018 • E&MJ 63 SUPPLIERS REPORT Investing in Innovation. The company also acts on data arriv- ing through its enterprise-wide incident reporting system, called Velocity, which allows the company to track trends in worker health and safety. Having seen a handful of inventions through prototype testing and having learned from the process, Nilsson said going forward he hopes the partnership with the university will remain strong. "We want to work closer with universities because you have facili- ties, you have individuals, like students, who are full of ideas and competence, and you have professors who can guide students in the right direction," Nilsson said. "We at Kal Tire can come up with a vision and say this is what we want to do, or ask how we can do this differently, and the university resources are funda- mentally helping toward the realization of our goal or vision." Atmospheric Monitoring System Improves Post Blast Re-entry The smartsense fi xed monitor SSFM-100 is a con fi gurable multi- gas, four-channel high-accuracy gas monitor with full range tem- perature compensation. Developed by Becker Varis, the product line has been designed to meet international standards and reg- ulations. Its all-in-one package eliminates the need for complex cable connections and troublesome programming. With its in- tegrated controller, the unit also functions as a black box-stor- ing critical information such as calibration records, alarm his- tory and data logging for post-accident investigation. Three fully programmable alarm set points for Alarm and Output controls along with Short Term Exposure Limit (STEL) and Time Weighted Average (TWA) limits displayed on the extra-large LCD display makes it possible to view the reading from up to 5 meters away. An auto-adjustable backlight and a wide range of mounting and connectivity accessories make it suitable for both underground and surface applications. The system requires a minimal amount of preventive maintenance outside the normal practice of cal- ibration. The SSFM-100 has an exceptionally long sensor life, according to Becker Varis. Calibration for the system is straightforward, with no need for complicated cables and connections. A custom accessories kit with calibration gases contains everything that is needed for calibration. The setup is an intuitive process: Simply put in the password and follow the screen prompts. A watchdog feature will alert the user or maintenance staff of any system errors includ- ing when the system has detected inaccurate measurements or calibration errors both locally through the maintenance LED and remotely on the supervisory platform. To accommodate site-speci fi c needs, smartsense has been developed as a hybrid system that is customizable to each cli- ent's installation requirements including copper (RS485/Eth- ernet), radio frequency (UHF-VHF Data Radio/ Wi-Fi) and fi ber optics data connectivity. An underground met- al mine located near Sudbury, Ontario, Can- ada, that was familiar with smartsense came to Becker Varis looking for a solution to post-blast, re-entry times. The standard procedure had them waiting a min- imum of 45 minutes prior to re-entry although most calculations showed that it should only take 10 to 15 minutes for the gases to clear. There was obvious potential for reduced downtime and im- proved productivity, but without the proper information available to them there was nothing they could do but wait. Implementing the smartsense system allowed them to reduce the average post blast re-entry downtime to 12 minutes, which raised the number of blasts immensely. Record-breaking 'Mass Blast' Dyno Nobel announced 1,461 DigiShot Plus detonators were used in a record-breaking blast at the Renard kimberlite mine in Quebec. The company described it as the largest underground blast on record that has been initiated with their electronic ini- tiation system. The Renard mine called the stope shot a "Mass Blast," Dyno Nobel reported. A total of 265,000 projected tons of explosives were used to load the shot. The downholes had a diameter of 6.5 in. and the upholes had a dimeter of 4.5 in., and all hole depths varied from 25 m to 65 m. The blast was initiated from the surface to ensure the safety of mine employees. The use of DigiShot Plus allowed the mine to maximize timing accuracy and also tie in a large quantity of detonators while maintaining testability of the detonators, Dyno Nobel reported. The Renard mine is located approximately 250 km north of Mistissini in the James Bay region. Fast lead times and exceptional value on new slurry pumps for a wide variety of applications!
