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 October 9, 2016, a 61 year old Equipment Operator, with 3 years of experience, was fatally injured at a sand surface mine. The victim was attempting to attach a screen plant to a front-end loader by hooking them together with a steel cable when the equipment moved pinning the victim. The victim was later discovered injured and leaning against the loader bucket. The victim died of his injuries the following day.
On September 21, 2016, a 52 year old contract drill operator / mechanic, with more than 30 years of experience, was killed at a limestone mine while performing maintenance on a truck-mounted rotary drill. At the time of the accident, the victim was attempting to remove the spindle cap from the top of the drill head while standing on the drilling deck. The victim was using a modified pipe wrench in an attempt to loosen the spindle cap using the machine’s drill rotation hydraulics by reaching into the operator’s compartment. As the victim activated the drill rotation lever, the wrench swung and struck him. The force of the impact knocked him against the operator’s cab, denting the frame and breaking the side window while the rotating wrench pierced his abdomen. As the victim attempted to climb down an adjacent step ladder, he was observed falling to the ground and striking his head. The victim was transported to a local hospital and died later that day as a result of his injuries.
On August 9, 2016, a 33 year old Leadman Contractor, with 4 years of experience, was killed at a cement plant loadout. The victim was attempting to replace the lift cable pulleys on the barge loadout chute, when the anchor point for the temporary rigging separated from the loadout chute and it unexpectedly fell. The falling loadout chute caused the lift cables to tighten and the lift cables pinned the victim to the loadout chute causing fatal injuries.
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 April 11, 2016, a 61-year old dozer operator with 18 years of mining experience was fatally injured at a surface titanium ore mine. He had been leveling the haul roads into the pit with the dozer and was found lying approximately 30 feet in front of the dozer.
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 December 15, 2015, a 75-year old tow truck laborer was killed at a cement plant. As the tow truck operator was lowering the truck’s boom it struck the victim. The victim suffered a severe head wound but was conscious when transported to a local hospital but later died of his injuries.
