Environmental Perspective of Stone Crushing and Quarrying

1. Stone crushing and quarrying units operating in the area must install proper dust containment and water sprinkling system at different dust emitting points to arrest the escaping dust. 2. Boundary wall must be provided and green belt along the boundary wall must be developed by the stone crushing units. 3.

Evidence for quarrying methods and vessel finishing techniques demonstrate that the Dorset practiced a narrow range of techniques to produce a limited range of vessel types over time. On the basis of the relative size and shape of soapstone vessels and residue patterning, previous archaeological investigations of Dorset vessels only recognized two main vessel types: oil lamps, and cooking pots.

Quarrying an overview ScienceDirect Topics

The quarrying operation cuts a block of stone free from the bedrock mass by first separating the block on all four vertical sides, and then undercutting or breaking the block away from the bedrock. If the block is large, it is called a “quarry block” and will be cut into smaller blocks at the quarry.

2015-3-4  Quarrying techniques During the Pharaonic Period, quarry-ing largely involved the extraction of loose boulders. They were worked with hammer stones (pounders) of dolerite originating from dykes in the granitoids, or (less common) aplitic granite. Such pounding is among most scholars con-sidered to be the only technique involved
