Study Notes
Mining Methods
-
Surface Mining: Involves removing overburden to expose minerals. Common techniques:
- Strip Mining: Horizontal layers are mined in strips.
- Open-Pit Mining: Excavating a large pit in the ground.
- Mountaintop Removal: Topping mountains to access coal seams.
-
Underground Mining: Extracts minerals from below the earth's surface. Techniques include:
- Room and Pillar: Creating rooms while leaving pillars of material for support.
- Longwall Mining: Using a long wall of coal, fully extracting the mineral with minimal leftover.
- Sublevel Stoping: Mining ore in horizontal slices with minimal waste.
Geological Surveying
- Purpose: Evaluates geological conditions to locate minerals, assess reserves, and determine mining viability.
-
Methods:
- Geophysical Surveys: Utilizing magnetic, gravity, and electrical methods to identify ore locations.
- Geochemical Sampling: Analyzing soil or rock samples for mineral content.
- Remote Sensing: Collecting data via aerial or satellite imagery to assess land features.
Safety Standards
- Regulatory Bodies: Organizations like MSHA enforce safety regulations in mining operations.
-
Common Standards:
- Personal Protective Equipment (PPE): Helmets, gloves, masks, and safety boots are mandatory.
- Ventilation: Ensures fresh air circulation, particularly in underground mines.
- Emergency Response Plans: Must be established and regularly drilled.
- Training: Regular safety training sessions for employees on equipment, hazard recognition, and emergency procedures.
Terminology
- Ore: Naturally occurring solid material from which a metal or valuable mineral can be extracted profitably.
- Overburden: Soil and rock that lie above a mineral deposit, often removed in surface mining.
- Tailings: Waste materials left after the extraction of valuable minerals, often stored in tailings dams.
- Grade: The concentration of a mineral within an ore, usually expressed as a percentage.
Interpreter
- Role of Mining Interpreters: Specialists who translate geological data into actionable mining plans.
-
Functions:
- Data Analysis: Evaluate geological surveys and mapping data for mining feasibility.
- Communication: Act as a liaison between geologists, engineers, and management.
- Regulatory Compliance: Ensure that mining plans meet legal and environmental regulations.
Mining Methods
-
Surface Mining: Removes layers of earth to access minerals beneath.
- Strip Mining: Extracts minerals in horizontal strips.
- Open-Pit Mining: Excavation creates a large pit.
- Mountaintop Removal: Entire mountaintops removed to access coal seams.
-
Underground Mining: Extracts minerals from beneath the surface.
- Room and Pillar: Creates rooms for mining, supported by pillars of material.
- Longwall Mining: Continuously extracts coal from a long wall, leaving minimal waste.
- Sublevel Stoping: Mines ore in horizontal slices, minimizing waste.
Geological Surveying
- Purpose: Identifies mineral locations, assesses reserves, and determines if mining is feasible.
-
Methods:
- Geophysical Surveys: Uses magnetic, gravity, and electrical methods to locate ores.
- Geochemical Sampling: Analyzes soil or rock samples for mineral content.
- Remote Sensing: Collects data via aerial or satellite imagery to assess land features.
