- 2. OPPORTUNITIES Demand far exceeds supply for entry-level Mining Engineers Many are unfamiliar with the mining industry and its career opportunities Scholarship opportunities
- 3. Graduate Mining Engineering Trend The upsurge in mining engineering graduates in the late 1970’s was due to the energy crisis. Downward turn was a correction in the supply vs. demand relationship and low coal and mineral prices. Recent market conditions and future projections indicate an increase in mineral and coal demand. Currently graduating about 140 per year in the U.S.. Study found that 300 new graduates per year will be needed over the next 10 years.
- 4. Mining Engineer Graduate Demand (5% Growth Scenario) 52% of the mining engineers in the U.S. are over 50 years of age. Based on a retirement age of 65, approximately 300 new mining engineering graduates will be needed over the next 10 years to meet the demand.
- 5. Career & Salary Growth Potential ‘Show me the money!’ Due to the retirement rate and the growth in the minerals industry, career growth is accelerated. Potential to achieve upper level management position in less than 10 years. Salaries are 2005 data. Current 2007 starting salaries are in the $55,000 - $60,000 range.

- 16. WHAT DOES A MINING ENGINEER DO? Responsible for the safe, economical, and environmentally sound operation of mines. Find, extract, and prepare coal, metals, and minerals for use by manufacturing industries and utilities. Design open pit and underground mines, supervise the construction of mine shafts and tunnels in underground operations, and devise methods for transporting minerals to processing plants. Some develop new mining equipment or direct mineral processing operations to separate minerals from the dirt, rock, and other materials with which they are mixed.
- 17. VARIOUS SPECIALTY AREAS • Ground control and excavation design • Ventilation systems design • Mineral processing • Geological modeling and reserve analysis • Power system design • Material handling system design • Economic feasibility • Operations and corporate management • Others
- 18. GEOLOGICAL ENGINEER 1. Direct drilling programs & apply geological interpretations. 2. Make computerized maps. 3. Applying geological knowledge to directing mining, processing and research groups. 4. Work environment variety: hiking surface, climbing underground, corporate office presentation. TYPICAL JOB TASKS
- 19. MINING ENGINEER 1. Determine of best mining practice. 2. Minimize ground disturbance. 3. Survey operations to determine production levels. 4. Design explosive and blasting operations. 5. Develop optimum materials handling systems. 6. Evaluate operational efficiency. 7. Develop ventilation & safety engineering strategies. TYPICAL JOB TASKS
- 20. Longwall Mining Underground mining method used in flat lying deposits and mostly in coal. Mines the coal in large blocks of approximately 10000 feet by 1000 feet. Shields (shown in picture) run across the 1000 foot face and support the roof while a shearer removes the coal from the face. As the shields move forward, roof caves in behind.
- 21. Room-and-Pillar Mining Continuous miner cutting and loading coal Roof bolter installing roof bolts for roof support Shuttle car being loaded Shuttle car discharging load Conveyor belt Feeder/breaker Application in flat lying deposits. Coal, aggregates and minerals extracted using this technique. Extraction achieved by either: 1. Drilling & Blasting or 2. Continuous Miner.
- 22. Sublevel Caving Underground mining technique for fairly steep deposits (>60o). Weak to strong ore and rock. Typically used for sulfide ores or precious metals. Mining is performed downwards from the top of the ore body.
- 23. Mineral Processing Engineer 1. Design the processes & flow sheet needed to produce a valuable material. 2. Develop & direct the processes that separate minerals from other minerals. 3. Optimize processing operations to ensure maximum profitability. 4. Produce a product that can be transported. 5. Apply processing to reduce environmental impacts. TYPICAL JOB TASKS
