Ground Control <Legit | GUIDE>
: Using instruments like borehole pressure cells (BPCs) and extensometers to track ground movement and stress changes.
: Mine operators are often required to maintain a Ground Control Management Plan (GCMP) to document their approach to assessing and controlling geotechnical hazards. 2. Surveying & Drone Mapping Ground Control
In the mining industry, ground control is the science of studying and controlling the behavior of rock strata in response to mining operations. Its primary goal is to prevent the collapse of mine openings by managing stresses and providing artificial support. : Using instruments like borehole pressure cells (BPCs)
: Installing rock bolts (1.5–2.4 m) and cable bolts (4–12 m) to pin large blocks of rock together. Surveying & Drone Mapping In the mining industry,
: It is one of the most vital safety aspects, as roof, rib, and face falls were responsible for nearly 40% of all underground fatalities between 1999 and 2008. Key Techniques :
: Optimizing the size of left-behind ore "pillars" to support the roof.
In photogrammetry and aerial mapping, are physical markers placed on the ground with known precise coordinates. Ground control points: why are they important? - Pix4D
