Main parameters for drilling & blasting in surface mining include blast design, hole diameter, hole depth, explosive type, and blast timing.
Blast design: determining the layout, pattern, and sequencing of blasts to optimize fragmentation and minimize environmental impact
Hole diameter: the size of the drill hole affects the amount of explosives needed and the resulting fragmentation
Hole depth: deeper holes allow for lar...
Bench benches are typically categorized as production benches, development benches, and service benches in a mine.
Production benches are used for extracting ore and are typically larger in size.
Development benches are used for infrastructure development within the mine.
Service benches are used for maintenance and support activities.
Each type of bench serves a specific purpose in the mining operation.
Cycle time in transportation of raw materials refers to the total time taken for a round trip of transporting raw materials from one point to another.
Cycle time includes loading, transportation, unloading, and any waiting time in between.
Efficient logistics planning can help reduce cycle time and improve overall productivity.
For example, if it takes 2 hours to load materials, 1 hour to transport them, and 1 hour to unl
The number of trucks for loading equipment can be determined based on factors such as production capacity, distance to transport, and availability of loading equipment.
Consider the production capacity of the mine to determine the number of trucks needed for efficient transportation.
Evaluate the distance that the trucks need to travel to transport the materials and adjust the number of trucks accordingly.

Java 17 introduces sealed classes to restrict inheritance and improve code maintainability.
Sealed classes are declared using the 'sealed' keyword followed by the permitted subclasses.
Subclasses of a sealed class must be either final or sealed themselves.
Errors may occur when trying to extend a sealed class with a non-permitted subclass.
