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.
- Ensure that miners who install, remove, or maintain shields are trained on proper procedures.
- Never remove hydraulic components without first determining if they are pressurized and/or supporting weight. Ensure all stored energy is released or controlled before initiating repairs.
- Never work on hydraulic components of both supporting cylinders of longwall shields simultaneously. A shield can collapse if hydraulic components from both cylinders are removed, even if both cylinders have functioning pilot valves.
- Never work on a component that supports a raised portion of the shield unless the shield is blocked against motion.
- Be aware of potential pinch points when working on or near hydraulic components. Examine work areas for hazards that may be created as a result of the work being performed.
- Maintain good communication with co-workers. Make sure those around you know your intentions.

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.
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.
