Methods of extraction of natural stone

Currently, there are three main methods of extraction of natural stone.

The first method is blasting. When using this method, holes are drilled in the rock, where charges with explosives are laid and then explode. This method is the cheapest and available, but has a disadvantage, which consists in the appearance of microcracks in the structure of the stone, resulting in the rock crumbles, its overall quality deteriorates significantly.

The second method of extraction of natural stone is called "air cushion". It consists in the fact that holes are made in the rock, where a reservoir is placed, which is filled with air under high pressure, as a result of which cracks appear and the rock is fractured. In this method, it is possible to avoid microcracks and crumbling of the stone, thereby increasing the total amount of extracted raw materials.

The third method of extraction of natural stone is carried out by means of a stone cutter. This is the most expensive, but also the most effective way, when high-tech machines with special saws cut the rock into smooth blocks, without damaging the structure of the stone and preserving its natural qualities.
