Environmental sustainability assessment due to stone quarrying
23/11/2020Quarrying is the way toward acquiring quarry materials, for the most part, rocks found on or underneath the land surface (Banez et al. 2010 ). Quarrying badly affects the environment in many ways in the course of the investigation and blasting, delivering, and removal of waste rocks (Maponga and Munyanduri 1998 ).

To Use or Not to Use a Minoan Chisel? Ancient Technology in a
15/05/2014Basically, chisel-work on stone concerns three different working actions: quarrying, dressing and sculpting. Evidence of all these working actions can be detected in the Minoan material. In this section I will consider Minoan quarries and in addition bring forward material from Egypt to further substantiate the use of the bronze chisel in quarries.

19/09/2020And so, the early quarrying techniques involved pounding the base of the stone blocks in order to separate them into large pieces. This was done on hand using nothing but stone hammers made from dolerite. Hammers made from other similar materials have been discovered but dolerite was the predominant stone used.

quarrying
The quarrying technique involves deep drilling and blasting to break the rock. When usable rock is found, the surface is cleared. A cut, or channel, is made to separate the rock from the solid bed, or mass. Large blocks are separated from the parent mass, sometimes with the use of low-powered explosives.

Building stones of Edinburgh: quarrying methods
The quarrying process was started by 'miners' who drove horizontal mines near the top of the post (bed). Quarrymen then wrought downwards from the mines, a few feet of solid sandstone being left to support the roof. Mining continued until about 1907 when a serious roof fall killed 5 men.

The Greeks began excavating* these sites in the 700s B.C. as a way to extract the stones. Greek quarrying techniques changed very little over the centuries, and the Romans later adopted these methods to extract stones on a much wider scale. The Greeks and Romans built quarries wherever there was a valuable source of stone.

The quarry worker works down the row, inserting a wedge between each pair of feathers and then tapping the wedges with a sledgehammer. This forces pressure from the wedge to the feathers so that eventually a crack line forms. This procedure is commonly followed to form the bottom of a block and for dividing large blocks into smaller blocks.
