What is the primary purpose of mine development?

Solution (By Examveda Team)

Definition of Mine Development:
Mine development refers to the set of activities undertaken to prepare a mineral deposit for production. It involves the construction of shafts, adits, declines, drifts, crosscuts, and other underground or surface infrastructure required to reach and access the ore body. This phase comes after exploration and before the actual extraction of ore.

Correct Answer: Option C: Accessing ore body
The primary purpose of mine development is to access the ore body so that it can later be extracted efficiently and safely. Development creates the physical infrastructure that allows workers, equipment, ventilation, and materials to reach the ore. Without proper development, mining cannot begin.

Key components of mine development include:
• Shafts – Vertical openings used for transporting miners, equipment, and ore.
• Declines or ramps – Inclined tunnels that provide vehicle access between levels.
• Drifts and crosscuts – Horizontal passages used to reach the ore body and provide pathways for ventilation, drainage, and utilities.

All these elements are essential for setting up the operational framework of a mine, making ore accessible for subsequent extraction.

Explanation of Other Options:
Option A: Extraction of ore
Extraction is the next stage after development. While development may involve limited ore removal, its main goal is not extraction but preparation.

Option B: Ventilation planning
Ventilation is an important part of mine design but is not the primary goal of development. It is planned as part of the overall infrastructure to support access and safe working conditions.

Option D: Waste disposal
Waste disposal is a part of mine operations and environmental management. It is not a core function of development itself, though development work may include access to waste storage areas.

Conclusion:
The correct answer is Option C: Accessing ore body, as mine development is fundamentally aimed at creating the necessary infrastructure to reach and prepare the ore body for mining operations.
