Oct 01 2021 Due to its good offroad capability it outperformed the other surface mining machine that we tested and Vermeer AG has proven to be a good partner for our organisation Moving forward we will likely continue to use drilling and blasting methods in limestone but believe that the Vermeer Terrain Leveler SEM will help us address the concerns Apr 07 2014 Modern machines like continuous surface miner can however eliminate the need of drilling and blasting in certain surface mining operations Successful drilling under specific site conditions requires blending many technologies and services into a coherent efficient team particularly if it is for deep exploration drilling
