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.
- Do not weld, cut, or solder with an arc or flame where methane is detected in excess of 1% by volume. Provide supplemental ventilation in work areas where methane may be encountered.
- Conduct proper examinations for methane immediately before and periodically during welding, cutting, or soldering, especially in areas likely to contain methane. Perform examinations with properly calibrated methane detectors that are capable of detecting concentrations greater than 5%.
- Ensure smoldering metal or sparks from welding, cutting, or soldering do not result in the ignition of combustible materials or methane. Install non-combustible barriers below welding, cutting, or soldering operations in or over a shaft.
- Provide adequate training on the characteristics of mine gases and in the use of handheld gas detectors, including the use of extendable probes or pumps.
- Always use non-sparking tools when working where there is a potential for flammable or explosive methane concentrations and, when practicable, utilize options which do not involve welding or cutting when working near these areas.

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.
On June 6, 2016, a 34-year-old contract laborer with 7 years of mining experience was fatally injured when a diesel-powered front-end loader fell on him. Working together, another miner and the victim lowered the bucket and put downward hydraulic pressure on the bucket to raise the middle of the loader. Both miners then crawled under the loader. The hydraulic pressure released, allowing the loader to lower, pinning both miners. A mine examiner, who was nearby, lowered the bucket again to raise the loader off the miners. One miner was freed and assisted in removing the unresponsive victim from under the loader. Cardiopulmonary resuscitation (CPR) was performed, but the victim could not be revived.
On Friday, March 25, 2016, a 48-year-old continuous mining machine operator, with 30 years of mining experience, was fatally injured when an overhanging section of a rock rib fell and pinned him against the haulage equipment. The fallen rib was approximately 44 feet long, 4 feet wide, and 2 feet thick. The victim was remotely operating a continuous mining machine that was being used to excavate material during the construction of a coal transfer shaft. The area where the accident occurred had a depth of cover of approximately 1,950 feet and a height of approximately 17 feet.
On Tuesday, January 19, 2016, a 36-year-old continuous mining machine operator was fatally injured when he was pinned between the conveyor boom of the remote controlled continuous mining machine and the coal rib while positioning the trailing cable. The victim had trammed the continuous mining machine back out of the No. 6 Face into the last open crosscut between No. 6 and No. 5 Entries. The victim had 5 years and 6 months of mining experience, with 1 year and 17 weeks experience as a continuous mining machine operator.
On January 16, 2016, a 31 year old continuous mining machine operator with 12 years of mining experience was fatally injured when a section of coal/rock rib measuring 4.5 feet long, 3 feet high, and 3 feet thick fell and pinned him to the mine floor. The victim was remotely operating the continuous miner in the number 2 entry of the advancing section when the accident occurred.
On Monday, January 4, 2016, a 53 year-old belt foreman/fireboss with 34 years of mining experience was fatally injured when he came in contact with a moving underground belt conveyor. The victim was preparing to change out a hold up roller when he was caught by the moving belt and pulled into the roller.
