Mine. “These mines have environments with continual acid renewable runoff at pHs of 1.8 at concentrations of 15%. The coated bolts were cored out and had no corrosion. “There were also no inclusions in the coating after achieving yield loads.”The newly introduced DSI Truss Eye.Another new addition to the DSI product line is the Threadbar Truss System, which offers structural rigidity and support in coal applications, and another soon to be introduced, the DSI Truss Eye.“Truss systems are becoming more popular where a longwall headgate entry height is critical for a stageloader to pass as the longwall face advances,” said DSI Director of Rock Mechanics Dr. Jinsheng Chen. “It also provides support to fracturing and exceptionally soft ground to minimize roof sagging or failure.” The Truss Eye, which DSI said makes installations easier and less expensive, is also lighter with ergonimical advantages for the installer.Finally, DSI’s development team is working to unveil the TensionLoc tensionable bar. With a design that is headed, versus the current industry standard tensionable rebar that uses a nut and crimp, this allows for faster installation times and a reduction in operational installation costs for mines. It also offers a lower profile extension, with only a square head protruding.
