What is rock blasting?
Rock blasting is the process of drilling holes in a rock mass at depths, and spacing to allow an explosive to fracture the rock. In this process, the rock must fracture enough to be broken down to the size intended. It is practiced most often in mining, quarrying, and civil engineering such as dam, tunnel, or road construction.

Mining and Quarrying
The main source processes generating this type of waste are physical and chemical processing of ornamental rocks, mining and quarrying works and alumina production. Wastes belonging to the EWC code 10 are wastes from thermal processes: power stations and other combustion plants (except those classified as EWC 19), iron and steel industry and aluminum, lead and zinc thermal metallurgy.

Quick Guide to Soft Rock Mining | Underground Mining
Soft rock mining refers to the process of extracting soft underground minerals such as oil, coal, shale, and potash from soft rock mineral resources. Since mineral deposits of soft or sedimentary rocks are evenly layered and relatively soft, methods for mining such materials are much more different from those used to extract hard rock minerals.

What Is Quarrying? Same with the Mining?
Quarrying involves working on the surface of the earth to extract minerals and other materials. It is the process of disintegrating rocks, removing sand, gravel, or other minerals from the ground as raw materials for construction and other purposes. In Malaysia, the task is usually carried out by a quarry company. Centuries ago, quarries were carried out with hammers, chisels, and picks made

Quarrying is a term used to describe a specialized open-pit mining technique wherein solid rock with a high degree of consolidation and density is extracted from localized deposits. Quarried materials are either crushed and broken to produce aggregate or building stone, such as dolomite and limestone, or combined with other chemicals to produce cement and lime. Construction materials are

Quarrying
In surface mining and quarrying, the original soil is lost and degraded, and only skeletal materials (original host rock) are left exposed and bare. Surface soil removal immediately damages the structure and organic matter content, nutrients and water amounts, soil temperature, and the activity of most of the organisms involved in biogeochemical processes ( FAO and ITPS, 2015; Larney and
