Final answer:
The main objective of providing ground support is to ensure the stability of the mine drift in underground mining. Ground support systems such as bolting, shotcreting, and rock anchors are used to reinforce the surrounding rock mass and prevent deformation. If the supported wire is displaced vertically, it remains in stable equilibrium; if displaced horizontally, it may become unstable.
Step-by-step explanation:
The main objective of providing ground support for stress-induced deformation in underground mining is to ensure the stability of the mine drift. Deformation in the form of subsidence, sinkholes, or collapses can pose serious safety risks to miners and compromise the overall structural integrity of the mine.
Ground support systems such as bolting, shotcreting, rock anchors, and mesh are used to reinforce the surrounding rock mass and prevent excessive deformation. These support mechanisms distribute the stress induced by the mining operations, reducing the likelihood of drift destabilization.
When the supported wire in a mine drift is displaced vertically, it remains in stable equilibrium as long as the support system can resist the gravitational forces acting on it. However, if the wire is displaced horizontally, it may become unstable and further ground support measures may be required to restore stability.
