Ground Monitoring | RockEng

Ground monitoring is essential in any underground mine. Ground Monitoring – The earth is far from static; on the contrary, there is continual movement all the way from the surface to deep underground. While this movement is generally very slow, incremental and completely natural, it also can pose significant risks for those in the mining sector – especially those who operate underground mines.
