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 analysisWhile 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.
Description of the MOSS (Miner Operated Survey System)
MS60 is capable of high-precision measurements in harsh environments
Proven Leica Technology with hundreds of instruments working in Ontario mines
MOSS runs with all current Autodesk based CAD software including Deswik, Amine, etc.
Daily headings are loaded onto a rugged tablet computer, interfaced using MOSS MS60
The MS60 is quickly setup on a tripod in an accessible area to the working face, then performs a 2-point measurement resection to accessible control points.
The location of the MS60 is displayed on the tablet computer within the mine design layout.
The miner selects the design centerline of the working drift. MS60 automatically projects the exact location of design onto the working face for the miner to mark with spray paint.
The miner locates laser pointer at the top left of the face opening and moves the laser along the blast opening from left to right across the back, down the right face/drift wall, along the floor/face wall, then back up the left face/drift wall.
The entire face opening is now measured, surveyed and displayed in profile for miner to evaluate actual blast face verses the mine design opening. MOSS software immediately displays over and under break as a graphic for the miner to evaluate.
The Tope Button which moves the MS60 and laser pointer along the left side of the face at a predetermined height off the floor (usually 1.5m) and then along the left drift wall. The MS60 is tracing the design grade line and taking tope measurements. The miner spray paints the laser as it moves from the centerline to the left drift wall. This same routine is performed on the right side of the centerline and moves along the right drift wall tracing out the design grade line and allowing the miner to spray paint the design grade line. The resulting grade line has be spray painted on both drift walls and across the face. The MS60 captures all the surveying data at the same time displaying the graphical tope lines to the miner for evaluation.
A Blast Pattern is selected from a pull down menu and the MS60 then moves and places the laser pointer on the exact collar location for the Jumbo Drill Steel. The Miner then follows with spray paint as all the collar locations are robotically marked out by the MS60 laser pointer.
The MOSS System will then project the entire drill pattern round and allow the operator to graphically position the Jumbo for the best possible location for custom rounds involving corners or junctions. The MS60 then traces a laser pointer on the back so the miner can follow with spray paint the proposed boom location for the best drilling azimuth.
procedure takes about 5 minutes and is valuable information for the Geology team to record each and every blast face with high resolution photography and point data for Geological Face and Structure mapping. An added benefit is all ground support is also captured with the measurement data for future reference.
The end result from this 20 minute activity is:
Every round is surveyed (Tope, back, floor)
Every face is profiled and evaluated for over/under break
Month End volume calculations are 80% more accurate and done daily
Exact design centerline and grade lines are marked for every round
Exact design drill steel collars are located on the blast face
Every face is scanned and photographed for Geological mapping
All ground support is documented
We estimate a 10% reduction in over break offering an immediate ROI
