Explosives have been used by humans as an effective tool since ancient times, typically in the art of war. Blasting, however, utilizes explosives in a constructive way by focusing the vast energy produced by the explosion …
The overview of role of rock mass properties, explosive parameters and blast design parameters on blasting outputs has been discussed in this chapter. The summary of discussions made in this chapter is as follows: I. The rock breakage during blasting takes place under the influence of shock wave and gaseous pressure. The selection of proper ...
Blasting has been one of the most important contributors of mining since the start of mineral extraction and excavation. Along with fragmentation of the rocks, blasting also produces an excess of energy in the form of heat and vibration. Due to the spread of the vibration, the surrounding environment gets affected. Therefore, this paper …
2. Introduction Shot Blasting is a surface treatment process using high stream of abrasive material. Mechanical force is used to propel blast media such as sand, sponge or glass beads at the surface to be cleaned to remove contaminants such as paint,rust, corrosive layer etc. Can be performed in closed environments like blasting …

Blasting modifies the surface state of materials in terms of surface irregularities too. Bearing in mind that the roughness characteristics affect the components functionality, it is essential to study and evaluation the surface state of pretreated materials. The chapter deals with evaluation of relation between individual surface roughness …
The standard shot blasting process is split into two key approaches, mechanical shot blasting and air blasting. No matter what process is selected, shot blasting involves the following steps- Examining the materials: Before beginning the shot blasting process, it is important to a) look at the materials to be treated, b) decide what the end ...
The PCA-SVM model was successfully employed to adjust blasting parameters of the No. 21 stope in Hongtoushan Copper Mine. Two blasting data sets were used to compare the capability of the PCA …
In grit blasting, wherever we cannot apply steel shots, we can go for soft media types like alumina, silicon carbide and walnut shells for non-metal surfaces like walls, wooden threshold, etc. In shot blasting, steel balls are best to clean up metal surface for cleaning, paint preparation and scraping away contaminants and rust.

The following results were obtained: (1) Shot peening maximum hardness is lower while depth of work-hardened layer is thicker. (2) Compressive residual stresses on the peened surface are larger than that of grit blasting. (3) Critical thickness of shot peening is about 50% thicker than that of grit blasting.
Shot blasting employs wheel blast equipment to propel abrasive materials like steel shot and grit onto surfaces for finishing. The process uses centrifugal force, …
