What is the term for any device or materials inserted into the ground to strengthen or support it?

The term that refers to any device or materials inserted into the ground to strengthen or support it is known as an anchor. Anchors are commonly used in various construction and engineering applications to provide stability by securing structures to the ground, preventing movement caused by external forces such as wind, seismic activity, or soil pressure.

In the context of mining and construction, anchors can help stabilize slopes, control rock falls, or support structures in challenging geological conditions. They can be made from various materials, such as steel or concrete, and can be designed in different shapes and sizes depending on the specific requirements of the project. The understanding and application of anchors are crucial for ensuring safety and structural integrity in mining and construction environments.
