Improving blast design for an underground mine development project.
RESPEC provided on-site engineering support to Continental Cement during an underground limestone mine development project. As part of that project, the mining contractor’s burn cut blast design failed to perform properly when the development decline transitioned from limestone to shale.
RESPEC worked with the explosives supplier to adjust the blast design to account for the change in material properties from limestone to shale. The new burn cut blast design performed more effectively than the original blast design.
