It takes a diverse team working together to ensure that mining operations are planned, executed and the land reclaimed to appropriate environmental standards. Environmental Protection Specialists at the Division of Reclamation, Mining and Safety specialize in many areas including geology, biology, wildlife management, range and soil science, mining engineering, hydrology and mine safety. Their teamwork and expertise ensure that mining is conducted in so that environmental impacts to water, air, land, wildlife and local communities are minimized, and that reclamation is performed for beneficial post mining land uses.

Geologists that work for the Division of Reclamation, Mining and Safety use their skills and training in many facets of mining in Colorado. They apply geotechnical techniques and principles to collect data, study rock, and earth materials and groundwater that affect the operation of active mines as well as the reclamation of abandoned mines.


Water is an important part of mining and reclamation in Colorado. As water moves through mine workings and waste piles it can become contaminated with metals and other elements. Exposure to storm water and erosion can cause mine waste piles to contaminate adjacent streams and rivers.

Hydrologists help determine how water moves through abandoned mine areas, and how that water interacts with the area's watersheds. By measuring the flow rates, pH (water acidity), and mineral and chemical content of water near mines, they can help us understand where to take action, and what to do.


With increased emphasis on protecting the environment, many mining engineers work to solve problems related to land reclamation and water and air pollution. Environmental engineers at the Division of Reclamation, Mining and Safety review mining and reclamation plans to ensure that environmental impacts to air, water, land and local communities are minimized.

Range Scientists

Range scientists are experts in reclamation science, such as topsoil handling, revegetation, and weed control.  They focus on revegetation efforts to ensure that mined lands are reclaimed to beneficial uses including wildlife habitat, public recreation, agriculture and rangeland.

Mine Safety Professionals

Safety training for the mining industry is an integral part of the Division of Reclamation, Mining and Safety. The Division conducts a variety of safety training courses for the mining industry. Mining safety professionals use their knowledge of mine design and practices to ensure the safety of workers and to comply with State and Federal safety regulations. They inspect mine workings, monitor air quality and instruct miners on how to identify and avoid hazards while working in a changing mine environment. Mine Safety professionals also inspect tourist mines. These mines offer a safe experience for tourists and visitors to Colorado's mining districts.


The Division of Reclamation, Mining &, Safety offers a wide variety of scientific and technical employment opportunities. Supporting these efforts are employees engaged in other challenging and important information and administrative activities, such as computer support and programming, budgeting and accounting, purchasing and contracting, records and data management, and geographic information systems.
