Lateral rocks

The structure of the layer of the useful minerals

LATERAL ROCKS, country rocks (EN: lateral rocks; DE: Nebengesteine; FR: roches encaissantes ou enclavantes; ES: rocas encajantes, rocas del respaldo; RU: боковые породы) are the rocks, which are located at the side of the deposition with the useful minerals, or are adjacent to this deposition.

In case of the horizontal embedment of the deposition, they name the underlying layer of the rocks as the soil (sole), and the overlying layer as the roof (ceiling). In case of the oblique embedment of the deposition with the useful minerals, they distinguish the lateral rocks of the hanging side (or of the hanging wall), which are located above the deposition, and the lateral rocks of the lying side (or of the lying wall), which are located under the deposition (see the Figure).

The properties and condition of the lateral rocks influence the choice of the system for the development of the useful minerals, the technical-economical indexes of the construction and operation of the mining enterprises. The dry and sturdy lateral rocks are most favourable for the development of the useful minerals.
