Drilling And Blasting In Open Cast Copper Rock Mines
Optimized design of drilling and blasting operations in
Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.

Open-pit mining Wikipedia
Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
The basic patterns of drill holes employed in opencast
• The basic patterns of drill holes employed in opencast mines are • Square Pattern • Staggered (or) Triangular pattern • Single row blasting pattern • Multi blasting pattern • Wedge cut pattern • Diagonal blasting pattern • Square Pattern: • This pattern can also be called as multi row pattern.

Case Study Cast Blasting Orica Mining Services
As the higher the drill angle the more the cast is, it is recommended to increase the drilling angle to 20 degrees. Larger diameter (229mm) is better suited for cast blasting for improved cast and cost. Cost analysis showed that designs with larger diameter blast holes lead to reduced mining cost and faster coal uncovery rate.
Blasting Techniques Used in Underground and Opencast Mines
Blasting Techniques Adopted in Opencast Mines: Efficient blasting should give such rock fragmentation as to eliminate the need for secondary blasting. The fragmented rock should be easily handled by the bucket of the shovel. For mineral which has to go to crushers, the size should not be more than the input size for primary crusher.
