4. Blasting. In this quarrying technique, an explosive is used to break up the rocks into smaller pieces. When hand rocks without fissures or cracks need to be broken into little pieces, this technique is utilized. Since the stone obtained during blasting is often tiny, it can be utilized as road metal, railroad ballast, concrete aggregate, etc.
One method commonly used to remove rock blocks in quarrying is the use of wire saw machines. Wire sawing is a technique that involves using a diamond-studded wire to cut through large blocks of stone or rock. It is particularly useful when dealing with hard and dense materials such as granite and marble. Quarrying of Stones

Most crushers used for aggregate production can be categorised as one of three main types: Compression crushers – which squeeze the material until it breaks. Impact crushers – which use the principle of rapid impact to shatter material. A ttrition crushers – which use both impact and grinding to shear material.
Abstract. This chapter is an introduction to the significance of quarrying from the point of view of anthropogenic geomorphology. As a consequence of the extraction of mineral raw materials, so-called 'mining landscapes' have emerged since the 19th century. The spatial distribution of quarrying of aggregates, and the characteristics and ...
