Underground Drilling and Blasting Training DVD - ACG
The Australian Centre for Geomechanics has developed this safety training DVD for underground metalliferous mine workers. To purchase this product or find out more information, visit http://www.acg.uwa.edu.au/shop#trainprods Overview All underground mine workers will be exposed to drilling and blasting processes. The aim of this new DVD is to provide workers with the critical knowledge on drilling and blasting to aid appreciation of the importance of these mining processes and their related hazards. The DVD features an introduction to the rock breaking process in mining, followed by a section on how to handle, store and transport explosive products. The third part of the DVD covers development drilling and blasting practices; and the fourth part discusses production drilling and blasting. Target Audience Underground mine workers - the need to identify the potential hazards of working near or with explosives, and the protocols of re-entering a working area after blasting. Workers responsible for development and production drilling and blasting activities. This DVD will review drilling and blasting fundamental concepts that are critical to achieving optimal rock breaking outcomes. All industry stakeholders - those keen to learn more about drilling and blasting in underground mines. Project Sponsors: Barrick Gold of Australia; BHP Billiton Olympic Dam; Dyno Nobel Asia Pacific; Gold Fields Australasia; Newmont Asia Pacific; Orica Mining Services; Xstrata Zinc.
Smarter development
Contractor Byrnecut Australia brought a Sandvik DD422i development drill to Western Australia’s Jundee gold mine in 2015 to test its automation benefits. During a three-month trial, Sandvik DD422i drilled in excess of 60,000 metres monthly. Consumable costs fell by 25 percent thanks to longer tool life and Byrnecut Australia halved its overbreak. More than a year later, Sandvik DD422i remains responsible for all development at the mine.
Miner Operated Survey System MOSS Setup Tutorial
Why Northern Survey Supply NSS has been automating Mine Surveying for decades. We’ve partnered with Precision Mining Systems, Autodesk and Leica Geosystems to create the absolute best solution for underground mining – MOSS - Miner Operated Survey System. We’ve been assisting underground mining operations achieve safety and productivity gains by adapting and embracing this new technology. Robotic Total Station with Scanning capabilities are recommended. MOSS interfaces to all existing Leica Robotic Total Stations, including the new Multi Scanning MS60 providing incredible measurement features. • The MS60 provides WiFi communication with exceptional Robotic Speeds and measurement captures • Fast and efficient Laser Tracking for Jumbo Drill Steel Collar Location • 3D Face Scanning supporting Geological Face Mapping • 3D Face Photography with point cloud overlay supporting Face Mapping and structure identification • CMS capability for Stope and Drift analysis While the TS12 and or the TPS1200 series robotic Total Stations will work, the workflow benefits of the MS60 Multi Station provide additional Geological measurements and quality control for Ground Control installation.

MOSS Miner Operated Survey System January 2017
The MOSS underground surveying software supports a wide variety of Leica Robotic Total Stations including the latest MS60 3D Face Mapping and Jumbo Drill Steel Layout system. MOSS incorporates the use of a Robotic Total Station to control all layout activities related to surveying and the design location of the Jumbo Drill Pattern layouts on active headings. The system/solution will reduce over-break by at least 10 percent, and while using this automation, MOSS reduces manpower at the face. With MOSS implemented in active headings we see a direct result to improved workflow and faster cycle times. The real-time data MOSS is able to capture and provide solutions for: Comparison between Mine Design and Actual Blast, Setting of Line and Grade, Collar Drill Hole Location, 3D drill Pattern Generator, Face Scanning and Photos, and Cavity Monitoring. The entire seven step process takes on average twenty to twenty five minutes. MOSS has proven direct cost savings due to the real-time data provided to the miner at the face. The data collected related to this process is a one man job, thereby reducing manpower cost while increasing safety by having less people in the development heading. See an immediate return on investment in direct relation to more accurate metrics to month end reconciliations and financials.

This machine is a Jumbo XE3.it has 3 arms for drilling in horizontal.Average drilling speed depending of terrain features is 2,4 m/min(this is for a good terrain whit hard stones). This machine is programed whit the master plans.You must programed it every day for get better precision in the blast.The holes numbers oscillate a funtion of the terrain, operating load, terrain failures.... For get a good blast whitout overbreak you must follow the terrain every day and set the drilling plan .

Celebrating Independence Day at The Shed with The Orrison Family
Today Brad Orrison, Brooke Orrison Lewis, and the entire The Shed Barbeque & Blues Joint family honor those who have served and those who continue to serve in America's Armed Forces. To me the Fourth of July is about paying respect where respect is due...to our troops. And gathering around with family, with friends to do what we do best -- barbecue," notes Brooke Orrison Lewis. "The Fourth of July to me is, to me, about of course is the Independence of our country and we are so fortunate to live here. And while we may not always agree on certain things, we still live in the best country in the world. But it also brings my mind to the troops because of my father who was a Bronze Star medalist in World War II and just passed away," added Linda "MaMa Shed" Orrison. "As so my mind on the Fourth of July goes to those people who are fighting and those who have fought to keep this country free. What better way to celebrate that than to have a bunch of friends over, break out the smoker and the grill, and just enjoy the love we have for each other. I also like for us to take the time to do something special like have a Military person come over."
