What is an Extraction and Mining Technician?
An Extraction and Mining Technician (often categorized as a Geological Technician or a similar mining-specific role) supports engineers and geoscientists in the extraction of materials like coal, minerals, and oil and gas. They operate specialized equipment, collect rock, soil, and liquid samples, prepare and analyze those samples in a lab, and monitor the site conditions to ensure extraction processes are efficient, safe, and adhere to environmental and quality standards.
Typical Education
An Associate's degree in Mining Technology, Geological Technology, or a relevant technical field is the common educational requirement, often complemented by specialized certifications in mine safety (MSHA training) and hands-on apprenticeship experience.
Salary Range in the United States
The U.S. Bureau of Labor Statistics (BLS) reports salary data for Geological Technicians, Except Hydrologic Technicians (which includes many mining-related technicians):
The median annual wage for Geological Technicians, Except Hydrologic Technicians, was $52,440 in May 2023. Wages tend to be higher in the Oil and Gas Extraction industry, with an annual mean wage of $91,280 in that sector.

Day in the Life
How to Become an Extraction and Mining Technician
- Obtain Technical Education: Complete an Associate's degree in a field like applied science, mining technology, or geoscience technology.
- Acquire Safety Certifications: Obtain mandatory safety training and certification from the Mine Safety and Health Administration (MSHA), which is required to work on most mine sites.
- Gain Field Skills: Seek co-op terms or internships to gain practical experience with core equipment, field surveying, and sample collection procedures.
- Master Equipment and Software: Become proficient in operating specialized testing equipment (like spectrometers or drilling rigs) and relevant geological software.
- Develop Specialized Knowledge: Focus on the specific type of extraction (e.g., coal, metal ore, or oil and gas) and master the associated regulatory and operational procedures for that industry.
Essential Skills
- Safety Compliance: Adherence to strict safety protocols (MSHA, OSHA) and the ability to recognize and mitigate on-site hazards immediately.
- Instrumentation and Calibration: Skill in operating, calibrating, and maintaining sensitive field and laboratory equipment used for testing and analysis.
- Sample Collection and Testing: Expertise in collecting representative samples (rock, fluid, air) and performing precise preparatory and analytical laboratory procedures.
- Data Recording and Reporting: Meticulous skill in logging all field observations, test results, and instrument readings accurately, often using specialized digital software.
- Mechanical Aptitude: Ability to perform basic maintenance and troubleshooting on the heavy machinery, sensors, and drilling equipment used in the extraction process.
Key Responsibilities
- Collect and Prepare Samples: Collect rock, soil, water, or oil samples from designated locations on the mine site or drill sites using specialized tools and ensure proper handling and labeling.
- Conduct Laboratory Analysis: Perform technical tests on collected samples to determine mineral content, grade quality, moisture levels, or chemical properties, using precise lab equipment.
- Monitor Site Conditions: Regularly check and record data on environmental factors, air quality, fluid pressure, or equipment performance using monitoring instruments to ensure operational parameters are maintained.
- Assist Engineers and Geoscientists: Support professional staff by running tests, organizing data, assisting with geological mapping, and maintaining the integrity of technical records and databases.
- Maintain Equipment and Tools: Clean, maintain, and perform basic repairs on sampling equipment, sensors, and instrumentation to ensure all tools are accurate and operational for field use.
Five Common Interview Questions
- "What is the procedure you follow to ensure a rock or soil sample is truly representative of the deposit you are testing?" This assesses your understanding of proper sampling techniques and quality control.
- "Describe your experience with MSHA (Mine Safety and Health Administration) regulations. What is the most critical safety issue you monitor daily?" This tests your commitment to and knowledge of mandatory workplace safety standards.
- "If a core sample analysis unexpectedly shows significantly lower grade material than predicted, what steps would you immediately take?" This probes your critical thinking, data integrity checks, and reporting process.
- "Walk us through how you would use a total station or GPS equipment to perform a survey or mark a specific drilling location on a large site." This assesses your practical field surveying and measurement skills.
- "How do you maintain accurate documentation and ensure the chain of custody for all the samples you collect and analyze?" This checks your attention to detail and adherence to quality assurance procedures.
