Mining to access the orebody (a term used in both surface and underground mining). Dilution. The undesirable lowering of ore grade by mixing waste material during blasting and mining. Dragline. A large excavation machine used mainly in surface coal mining to remove overburden (layers of waste rock and soil) covering a coal seam.
Serves as both a textbook and reference describing the principles involved in hard rock blasting in surface excavations and open pit mines. Volume 1 will introduce basic engineering concepts and building blocks that make up a blast design. Volume 2 provides additional depth and breadth for better understanding fundamental concepts in rock blasting.

Blasting in a mine generally occurs in two phases, primary blasting and secondary blasting. Blasting Primary Blasting is the activity in which in-situ rock is broken in both development and stoping and in surface mining by drilling holes in the rock, charging them with explosives and detonating the holes in a planned sequence.
Jul 28, 2017· 4 In mining operations, blasting has become a routine work. With proper understanding of the rocks and blasting methods, the mining work can be done effectively. 5. 5 The basic objectives of this report is to highlight the principles and practices adopted in rock blasting operations for mining
The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production costs.

Sep 04, 2019· A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil engineering application. The Industrial Revolution carried discoveries in explosives and initiation technologies. A specialization principle, therefore, operates between the military and civil application of
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation.It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction.The result of rock blasting is often known as a rock cut.. Drilling and blasting currently utilizes many different varieties of
Nov 01, 2018· 1. Introduction. Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling. For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc. Amongst these operations, drilling and blasting are known as the
