On February 23, 2017, a 62-year-old section foreman was seriously injured by falling roof rock in the No. 3 entry of the active working section. The rock fell from between roof bolts and was approximately 3 feet by 2 feet by 3 to 4 inches thick. First-aid was administered and the injured miner was transported to a medical center. Due to medical complications from the injuries he sustained, the victim died on April 6, 2017.
- Install the most effective roof “skin” control technique, screen wire mesh, when roof bolts are installed. Most roof fall injuries are caused by rock falling from between roof bolts (failure of the roof skin).
- Conduct thorough examinations of the roof, face, and ribs where persons will be working and traveling; including sound and vibration testing where applicable.
- Scale loose roof and ribs from a safe location. Danger-off hazardous areas until appropriate corrective measures can be taken.
- Be alert for changing conditions and report abnormal roof or rib conditions to mine management and other miners.
- Correct all hazardous conditions before allowing persons to work or travel in such areas. Install and examine test holes regularly for changes in roof strata.
- Propose revisions to the roof control plan to provide measures to control roof skin hazards.
- Know and follow the approved roof control plan and provide additional support when cracks or other abnormalities are detected. Remember, the approved roof control plan contains minimum requirements.

On Wednesday, March 30, 2017, at 2:09 am, a 33-year-old miner (auger operator/foreman) was fatally injured at a surface auger mine.

On February 27, 2017, a 43-year-old plant attendant, with approximately 13 years of experience, was fatally injured when he fell through a 27-inch opening in a plate press. The victim had climbed a ladder to repair a damaged plate when he fell about 19 feet onto a moving refuse belt. The victim was found in a transfer chute, approximately 55 feet down the belt from where he had fallen.
On February 3, 2017, a 54-year-old truck driver received hip and leg fractures when he jumped from the cab of his truck as it was overturning. The victim positioned the truck on the dump pad and began raising the bed. Material in the bed was frozen or compacted and created an uneven load. As the bed reached full extension, the truck fell over. Due to complications associated with his injuries, the victim passed away 7 days later.
On Thursday, January 26, 2017, a 42-year-old miner with 23 years of mining experience was fatally injured when he contacted a moving drive roller for the section belt. The victim was positioned between the guard and the conveyor belt drive when he came in contact with the shaft of the belt drive roller.
On December 2, 2016, a technical representative for a shield manufacturer, with 13 years of experience, received fatal injuries while adding components to the hydraulic system of a longwall shield. The victim was positioned inside the shield near the hinge point when the shield collapsed and crushed him.
On Friday, September 23, 2016, a 46-year-old miner was fatally injured in a vehicle accident that occurred along a portion of a mine’s access/haul road. The victim (passenger) and a coworker (driver) were traveling down an inclined portion of the road when the driver apparently lost control of the pickup truck, causing it to strike the road berm and roll over in the roadway.
On Friday, July 29, 2016, a 58-year-old miner with 40 years of mining experience sustained fatal injuries when an ignition occurred in the shaft he and another miner were working above. Two miners were welding threaded blocks to secure guarding around the drive-shaft between a motor and dewatering pump. Methane ignited within the shaft, and the victim was in the direct line of the ignition force. On August 4, 2016, the victim died from the injuries received during the accident.
On Monday, May 16, 2016, a 50-year-old motorman, with over 14 years of mining experience, was fatally injured when the diesel locomotive he was operating crashed through a closed airlock door. The diesel locomotive was pulling six drop deck cars and had stopped to allow another motorman operating a trailing locomotive to separate the cars to provide the clearance needed to pass through the airlock. As the other motorman was preparing to couple his locomotive to the cars, the train unexpectedly moved forward and continued away from him towards the slope bottom where it crashed through the closed outby airlock door.
