Best Practices:

•    Monitor flash-flood watches and warnings and other adverse weather conditions, such as severe storm events, that could affect the safety of mine personnel.  Use NOAA Weather Radio or a smartphone app to monitor hazardous weather conditions in your area.
•    Establish policies and procedures to provide adequate warning to all mine personnel of ongoing weather conditions pertaining to flash floods and other adverse weather conditions.
•    Establish policies restricting access to areas likely, or known, to be affected by flash floods or other adverse weather conditions.  Do not travel across flooded roadways.
•    Properly design drainage systems, especially in areas where the terrain enhances water runoff and flooding.  Changes in a watershed, such as timbering or surface mining, can increase water runoff and flooding.
•    Examine drainage systems and features to ensure they are functioning and unobstructed.

Additional Information:

This is the 22nd fatality reported in 2021, and the first classified as “Inundation.”

Best Practices:
  • Assure a safe means of access is provided and maintained to all working places.  Use personnel lifts or ladders to access elevated work areas safely.
  • Use fall protection when a fall hazard exists.  Ensure fall protection has a suitable fall arrest and secure anchorage system.
  • Examine work areas, tools, and equipment. Report and correct defects. Do not use unsafe equipment.
  • Assess risks and eliminate or control hazards before beginning maintenance activities. Do not place yourself in a position that will expose you to hazards while performing a task.
  • Train miners and ensure they perform work safely, use tools properly, and utilize personal protective equipment correctly.
Additional Information:

This is the 20th fatality reported in 2021, and the second classified as “Slip or Fall of Person.”

Best Practices:
  • Use fall protection when a potential fall hazard exists.  Ensure fall protection has a suitable fall arrest and secure anchorage system.
  • Examine working places to identify loose ground or unstable conditions before work begins, after blasting, and as changing ground conditions warrant.  Ensure examiners have adequate training and experience to recognize potential hazards.
  • Assess risks and control hazards before beginning work activities.  Remain a safe distance from cracks and any sign of unstable ground conditions.
  • Assure a safe means of access is provided and maintained to all working places.  Use personnel lifts and ladders, as required.
  • Train miners and ensure they perform work safely, use tools properly, and utilize personal protective equipment correctly.
Additional Information:

This is the 21st fatality reported in 2021, and the first classified as “Falling, Rolling, or Sliding Rock or Material of Any Kind.”

Best Practices:
  • Never perform work under raised machinery or equipment until such machinery or equipment has been securely braced in position, blocked and  secured against motion.  Be alert for hazards that may be created while the work is being performed.
  • Conduct repairs from a safe location per manufacturer’s recommendations.  Verify the release of all stored energy before initiating repairs.
  • Use a lifting device compatible with the load being lifted and ensure blocking material is competent, substantial, and adequate to support and stabilize the load.  Always use the manufacturer’s safety devices or features to secure components against motion, and secure assemblies that rotate to prevent movement.
  • Establish and discuss safe work procedures before starting any task.  Train miners in safe work procedures and hazard recognition.  Monitor personnel routinely to ensure safe work procedures are being followed.
Additional Information:

This is the 19th fatality reported in 2021, and the fourth classified as “Machinery.”

MSHA: Final rule on electronic detonators in metal and nonmetal mines now in effect

March 19, 2020

Washington — The Mine Safety and Health Administration’s direct final rule concerning advances in electronic detonators in metal and nonmetal mines has gone into effect, the agency announced March 18.

The agency first defined detonators in its regulations in 1979 as devices “containing a detonating charge that is used to initiate an explosive such as electric blasting caps and nonelectrical instantaneous or delay blasting caps.”

MSHA states it initially believed that definition provided a means for the “automatic inclusion” of new technology. In January 1991, the agency clarified that detonating cords are not included in the definition and divided detonators into two classes.

The final rule adds the words “electronic detonators” to its definitions in 30 CFR 56.6000 and 57.6000. It also includes a waiting period of at least 30 minutes for misfires of electronic detonators, or longer if the manufacturer recommends it (56.6310 and 57.6310). Additionally, electronic detonators are added to circuit testing rules (56.6407 and 57.6407) and for precautions during storms (57.6604).

The agency’s other explosive standards in 30 CFR 56 and 30 CFR 57 (Subparts E) still apply to electronic detonators.

“For those electronic detonator systems that the agency has reviewed, MSHA agrees with [the Institute of Makers of Explosives] that electronic detonators provide a working environment that is as safe or safer for miners compared to non electric and electric detonators because they provide for greater control of a blast,” the final rule states. “MSHA believes that recognizing electronic detonator systems as distinct from electric detonators will eliminate confusion over certain regulatory requirements.”

Hudbay Receives the Mine Plan of Operations for Rosemont

March 21, 2019

Hudbay Minerals said Thursday that it has received the approved Mine Plan of Operations for the proposed Rosemont mine project, the final step in the permitting process.

“Rosemont is now a fully permitted, shovel-ready copper project and we look forward to developing this world-class asset,” said Alan Hair, Hudbay’s president and chief executive officer, in a press release.

The MPO was received from the U.S. Forest Service about two weeks after the project received the Section 404 Water Permit. READ MORE
