Fatality #1 for Coal Mining 2011
On Thursday, January 27, 2011, a 19 year old underground miner with fifteen weeks of mining experience was killed when he became caught between the “V” shaped coal discharge guides adjacent to the discharge roller of the section conveyor belt. Both belt conveyors were operating at the time of the accident.
Best Practices
- Train all employees thoroughly on the dangers of working or traveling around moving conveyor belts.
- Never attempt to cross a moving belt conveyor, except at suitable cross-overs or cross-unders.
- Install proper belt cross-overs and/or cross-unders at strategic locations, when height allows.
- Be aware of locations where new miners are working or intend to travel.
- Provide belt conveyor stop and start controls at areas where miners must access both sides of the conveyor. These areas should be provided with adequate crossing facilities (e.g. cross-overs or cross-unders).
- Install adequate guarding at all conveyor belt pinch point locations.

Fatality #48 for Coal Mining 2010
On Saturday, December 4, 2010, a 32 year old contract truck driver with four years of experience was killed in a Powered Haulage accident on a coal mine haul road. The loaded truck struck the left berm on the elevated roadway and over-turned on the road, trapping the victim under the cab.
Best Practices
- Never operate a truck or other mobile equipment without using a seat belt.

- Train all employees on proper work procedures, hazard recognition and avoidance, and proper use of roadway berms.
- Observe all speed limits, traffic rules, and ensure that grades on haulage roads are appropriate for haulage equipment being used.
- Always select the proper gear and downshift well in advance of descending the grade.
- Monitor work habits routinely and examine work areas to ensure that safe work procedures are followed
- Maintain control of equipment at all times, making allowances for the prevailing conditions (low visibility, inclement weather, etc).
- Maintain equipment braking and steering systems in good repair and adjustment.
- Do not attempt to exit or jump from a moving vehicle

Fatality #46 for Coal Mining 2010
On Wednesday, October 27, 2010, 39-year old continuous mining machine helper, with approximately 4 years of mining experience, was killed when he was struck by a loaded shuttle car. The victim was in the No.7 Entry between crosscuts No.37 and No.38, repairing a ventilation curtain. This entry and adjoining crosscuts were being used to gain access to the ratio feeder, which was located in the No.6 Entry.
Best Practices
- Before performing work in an active haulage travelway, stop mobile equipment until work has been completed and communicate your position and intended movements to mobile equipment operators.
- Use approved transparent ventilation curtains to improve visibility.
- Operate mobile equipment at safe speeds and sound audible warnings when making turns, reversing directions, approaching ventilation curtains, and any time the operator’s visibility is obstructed. The sound level of audible warnings must be significantly higher than that of ambient noise.
- Place visible warning devices at all entrances to areas where work is to be performed in the active travelway of mobile equipment.
- Be aware of blind spots when traveling in the same areas where mobile equipment operates.
- Install proximity detection systems on mobile face equipment.
- Always wear reflective clothing, or use permissible personal flashing lights, to ensure high visibility when necessary to walk or work where moving equipment operates.

Fatality #45 for Coal Mining 2010
On October 11, 2010, a 56 year old roof bolting machine operator with 31 years mining experience was killed in a roof fall. The victim was standing beside the roof bolting machine when a portion of a rock brow fell from between the roof bolts and struck him. The rock was approximately 6 feet long and 3 feet wide, and varied in thickness from approximately 7 inches, up to 24 inches.
Best Practices
- Remain alert for changing roof conditions, and remove hazards immediately.
- Roof brows that are created by a sudden change in mining height can create unsafe roof conditions and may require removal and/or additional roof support.
- Know and always follow your Approved Roof Control Plan.
- Don’t leave freshly cut roof unbolted for long periods of time.
- Use roof screen, large roof bolt plates, or other surface controls to prevent rocks from falling between supports.
- Train all miners to identify unsafe roof conditions that are encountered daily.
- Conduct thorough examinations in areas where miners will work or travel before and after work is completed.
- Please see the following information related to roof bolter safety in the following links:
- MSHA – Safety Targets Program – Roof and Rib Falls (Coal)
- MSHA – Safety Targets Program – Roof Bolter Safety

Fatality #44 for Coal Mining 2010
On Friday, September 3, 2010, a 37-year old Truck Driver with approximately two years experience was killed when the haul truck he was operating struck another truck from behind. The lead truck had stopped short of the pit, while a bulldozer pushed up material for the track-hoe to load. The victim, returning from dumping, ran into the bed of the lead truck.
- Conduct adequate pre-operational examinations before placing equipment into operation and ensure all lights are operational.
- Use cab and vehicle marker lights at all times when vehicles are in use during low light conditions, even when stationary/parking.
- Provide adequate illumination for all work areas where visibility is critical.
- Maintain control of equipment at all times, making allowances for the prevailing conditions (low visibility, inclement weather, etc).
- Consider providing proximity detection devices to mobile equipment when the possibility of collision with other mobile equipment is present.
- Routinely monitor work habits and examine work areas to insure that safe work procedures are followed.
- Communicate actions and intent to co-workers, especially if non-routine or out of the ordinary.
- When waiting to be loaded, take the vehicle out of gear and set the parking brake.
- Stay alert, stay awake, and pay attention to the task.

The truck traveled approximately 11 feet up an embankment on the left side of the haulage road, and then abruptly traveled back across the haulage road. Afterwards, the truck impacted a 5 foot high berm, travelled over the berm, and dropped 72 feet to the mine pit below.
- Conduct pre-operational examinations on all mobile equipment.
- Do not exceed the truck’s capabilities, operating ranges, load-limits and safety features.
- Always wear a seatbelt when operating a haul truck or mobile equipment.

Fatality #42 for Coal Mining 2010
On Thursday, July 29, 2010, at approximately 11:55 a.m., the left side integral roof bolter operator on a continuous mining machine was fatally injured. The victim was struck with a portion of rib measuring approximately 276 inches long by 55 inches high and up to 16 inches thick. The accident occurred while cutting an overcast. The victim had installed one test bolt and was near the left rear bumper of the machine, when the accident occurred. The rock in the left rib sheared off pinning, the victim against the machine.
- Develop a plan for cutting overcasts and train miners in the procedures and precautions.
- Examine the roof and ribs frequently while working.
- Take down or support any loose ribs or roof adequately before working or traveling in the affected area.
- Be aware of changing roof and rib conditions, especially when working between the ribs and equipment.
- Unless necessary, do not position yourself between any piece of machinery and the rib.
- Where the mining process allows, remain within the confines of protective devices such as cabs, canopies and rib protectors whenever possible.
- Install additional rib support prior to mining in areas where the roof or floor is cut above or below the coal seam, especially overcasts, loading points, etc.

- Install proximity detection systems on mobile face equipment. See the proximity detection single source page on the MSHA web site.
- Use approved translucent check curtains designed to allow mobile equipment to tram through.
- Sound audible warnings when making turns, reversing directions, approaching ventilation curtains, and any time the operator’s visibility is obstructed. The sound level of audible warnings must be significantly higher than that of ambient noise.
- Be aware of blind spots when travelling in mobile equipment travel ways.
- Communicate your position and intended movements to mobile equipment operators.
