Employee unhooked lanyard and fell through roof resulting in fatal injuries.
Operator was using a 2 pound sledgehammer to remove a worn tooth from an excavator bucket. When the operator hit the worn tooth (one time) with the hammer, a metal shard broke off of the worn tooth and passed through the operator's pants and the top of EE's leather boots before penetrating the operator's left leg, just above EE's ankle.
Miner struck by 'clay boulder' when EE crawled into a feed hopper to clear an obstruction. The miner suffered muscle damage requiring hospitalization and medication. Diagnosed with Rhabdomyolysis. No broken bones were found during the examination.
Miner Suffered a laceration requiring 6 sutures to their left arm while removing a dryer expansion joint.
Miner suffered 3rd degree burns to the abdomen when a hose popped off the seal pump in the process of removal. Burns required debridement and an allograft.
While observing another miner removing teeth from an excavator bucket from approximately 5-6 feet away. The injured miner was struck in the hand by a shard of metal (approximately 4mm X5mm) that broke off of the excavator tooth.
Miner suffered pinch caused laceration to 5th digit of right hand when latch sprung open from tension on rotex door. Miner was in process of inspecting screens. Laceration required 3 sutures to close wound. Miner returned to work to complete shift.
Miner suffered crushing laceration to big toe on right foot when a counterweight fell, striking EE's foot. EE was wearing steel toe boots which protected the foot from more serious injury. The miners were in process of changing a belt on wet plant machinery. A come-a-long holding the counterweight slipped allowing the weight to fall.

The employee slipped while climbing down from an Excavator's tracks. EE had three points of contact and did not fall but sprained shoulder.
EE was traveling down the main entrance road, with EE's bucket down low and hit a pot hole. EE's bucket contacted the ground and the loader came to an abrupt stop and EE's improperly adjusted seat belt let EE bounce too far forward. EE slammed into the front of the loader causing a concussion (w/o LOC), small forehead cuts, and bruising.
Employee was adjusting the chain rigging on a dewatering screen motor. They hooked the rigging onto the fork of a skytrac. The skytrac operator did not wait for verbal confirmation or hand signals to begin lifting the load. Employee still had a hand on the chain and received a laceration on right hand ring finger.
An employee was driving the manlift around the side of the plant to look into one of the main feed hoppers to check for a material cog. A front wheel loader working in the area did not see the manlift and backed into it. This caused the employee to slam into the handrail. This caused a muscle contusion on EE's left leg.
