The implementation of fire-setting follows these steps:

  1. Preparation of the site: Identifying the geological structure and selecting appropriate areas for application.
  2. Firing materials: Utilizing combustible materials such as wood or coal, which are arranged to generate maximal heat.
  3. Ignition: Setting the fire while ensuring that it maintains a consistent temperature.

Temperature plays a pivotal role in rock breakdown. High temperatures can alter the mineral structure, making it brittle and susceptible to fracturing upon rapid cooling. The cooling process induces stress, which facilitates the disintegration of the rock. Thus, understanding temperature control is vital for optimizing the fire-setting process in mining.

How Fire-Setting is Implemented

Fire-setting is implemented through a systematic approach involving both preparation and execution. Initially, miners identify suitable rock formations, particularly those rich in mineral content, and begin the preparation process by constructing fires near the designated rock surface.

Once the fires are established, the intense heat causes the outer layer of the rock to expand. This thermal expansion induces tension within the rock structure, culminating in fractures as the cooler interior remains intact. The effectiveness of fire-setting largely depends on managing the fire’s temperature, crucial for achieving optimal rock breakdown.

As the process continues, the surrounding area may be subjected to repeated heating and cooling cycles, allowing for more effective fragmentation of the rock. The resulting fissures facilitate subsequent excavation, enabling miners to extract valuable minerals with greater efficiency.
