Ground Control (2025)

: Optimizing the size of left-behind ore "pillars" to support the roof.

: 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 : 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. : Optimizing the size of left-behind ore "pillars"

In photogrammetry and aerial mapping, are physical markers placed on the ground with known precise coordinates. Ground control points: why are they important? - Pix4D Its primary goal is to prevent the collapse

: Using instruments like borehole pressure cells (BPCs) and extensometers to track ground movement and stress changes.

: Installing rock bolts (1.5–2.4 m) and cable bolts (4–12 m) to pin large blocks of rock together.
