Underground Mine Dewatering Techniques

The presence of water in underground mines can halt operations, damage vehicles and equipment, and even risk contamination and becoming an environmental issue. Each mining site is different, so the nature and the extent of the flooding risk differs, but the demand for effective underground mine dewatering techniques is growing as mining operations are increasingly digging deeper.

Mine dewatering pumps

Submersible pumps or sump pumps for dewatering are essential tools for controlling water at mining sites and preventing flooding. Underground mine dewatering pumps are often submersible as they are better designed to handle debris without clogging, but there is a great deal of selection available for redirecting water underground.

The underground mine dewatering pump system that is chosen can depend on the specific layout of a mine, including the choice between using a single large pump to remove water or several smaller pumps in a multi-stage approach.

Mine dewatering pump selection

There are a lot of rugged, reliable underground mining dewatering pumps on the market, so mines will have no problem finding efficient equipment. The problem often lies with choosing the most suitable solution and weighing up the options between higher investment in larger pumps and the cost of excavation for space when using multiple smaller pumps.

This problem is solved by putting trust in mining safety experts who can find the best underground mine dewatering solution for a mine’s specific requirements. Along with an extensive stock of dewatering equipment, Carroll Technologies partners with Equipment Pro to custom-design pumping dewatering solutions for any situation. Equipment Pro’s pump vertical turbines and dewatering pumps can handle any type of pumping situation and have been by a range of industries across the US.

According to Carroll Technologies president, Allen Haywood: “Carroll provides Equipment Pro pump-turbine systems and different model pumps for different situations around mining facilities. We can arrange for there to be an automatic pumping solution so that there’s not a lot of maintenance required, and those pumps can turn on and turn off according to the volume of water that they need or that they want to keep a level down to.

“For any type of pumping requirements that a customer may have, large or small, a custom pumping solution can be designed. Large requirements may be a very complex situation with pumps, so we can build floating systems, pontoon systems, where these pumps are stationed.”

Additionally, Stancor Pumps has an extensive portfolio of MSHA-approved mine dewatering pumps designed to redirect water in confined spaces. The company’s portfolio includes the explosion-proof  P/S Series of heavy-duty, dewatering pumps that offer excellent wear resistance, as well as the SL Solids Seriesvortex trash pumps, SEW solids handling wastewater pumps, and SB Series of clean water dewatering pumps.

Other mining equipment experts include Mefcor, which offers simple clog-resistant pumping solutions for difficult dewatering applications. Mefcor underground dewatering pumps do not require a power source or maintenance.

MSHA Powered Haulage Equipment Safety Guidance

Powered haulage equipment poses unique challenges, from limited visibility to complex traffic management. To address these risks, the Mine Safety and Health Administration (MSHA) provides detailed guidance aimed at preventing accidents and fostering safer working environments.

Powered haulage accidents continue to be a leading cause of fatalities in the mining industry, with recent data highlighting their significant impact on miner safety. As powered haulage incidents account for a large proportion of mining-related deaths, the Mine Safety and Health Administration (MSHA) emphasizes the importance of adopting proactive safety measures to mitigate these risks. Ensuring compliance with MSHA’s powered haulage regulations and leveraging advanced technologies is critical to protecting lives and maintaining safe operations.

Understanding Powered Haulage Safety Risks

Powered haulage equipment encompasses haul trucks, service vehicles, belt conveyors, and other machinery used in surface and underground mines. These machines pose various risks, including limited visibility, poor communication, traffic hazards, and equipment malfunctions. According to MSHA, powered haulage incidents have historically accounted for a significant portion of mining fatalities and injuries.

MSHA’s Key Safety Recommendations

MSHA’s safety guidance provides actionable steps to mitigate risks across different areas of mining operations:

Improving Visibility

  • Blind spots are a common issue in large haulage trucks and other heavy equipment.
  • Best practices include:
    • Using strobe lights, high-visibility flags, or flexible whip antennas on smaller vehicles.
    • Installing cameras and proximity detection systems to alert operators of nearby hazards.
    • Training miners to recognize and avoid blind areas.

Enhancing Communication

  • Establish protocols for clear and consistent communication between operators and workers.
  • Use radios, hand signals, or visual cues to confirm movements and positions.
  • Ensure high-visibility clothing is worn at all times.

Traffic Management

  • Develop and maintain well-designed haul roads with proper signage, berms, and guardrails.
  • Implement traffic control plans, including designated routes and speed limits based on road conditions.
  • Train workers to stay within safe zones and avoid reversing equipment when possible.

Seat Belt Use

  • Mandate the use of seat belts to protect operators during rollovers or collisions.
  • Regularly inspect seat belts and replace worn components.

Conveyor Safety

  • Install guards to protect against contact with moving conveyor parts.
  • Follow lockout/tagout procedures during maintenance.
  • Provide safe access points and maintain clean walkways around conveyor systems.

Pre-Operational Inspections

  • Conduct thorough inspections of equipment before each shift to identify and address potential hazards.
  • Ensure only trained personnel perform these checks.

New Regulatory Requirements: Safety Program for Surface Mobile Equipment

In January 2024, MSHA introduced a rule requiring mine operators with six or more miners to develop a written safety program for surface mobile equipment. The program must:

  • Identify hazards and outline risk mitigation strategies.
  • Be updated regularly based on site conditions and feedback.
  • Engage miners and their representatives in its development.

Compliance with this rule is mandatory by July 2024, emphasizing the importance of tailored, site-specific safety measures.
