Contractor was servicing the brake pump on the hoist instead of the pump for the thruster brake. Thruster brake has its own brake pump, test trips rectified the problem. Evac called off before bringing people out of the mine.
When performing production hoist daily checks the hoist consistently failed static and drag tests.
Test trip was being done, track limit exceeded, NIDEC was on site to diagnose, troubleshoot and change out motor encoder and adjust parameters on drive, #3 hoist back up and running within 1.5 hours
Power brown out from NYSEG power supply, they were updating their system and power to our local grid was affected. #3 skip kicked out, reset, men brought to surface, ran test trips, all tested good.
#1 salt production skip kicked out, cage stuck. Inspection reveled pin was missing that held safety dog to skip. Dog did deploy correctly to stop cage travel as it should have.
#3 hoist tripped and would not reset because the west brake was not functioning properly. Through troubleshooting it was found that the west brake switch plunger was stuck in the open position.
While running the #3 hoist, the hoist tripped out. A magnet proximity switch was found to have shorted out within #3 shaft 90' below the collar.
A guide wheel on the #3 mancage broke, therefore the #3 hoist was down until repairs were completed. Upon completion of repairs, a shaft inspection was performed to ensure everything was in order and functioning properly.

An employee was in the process of shoveling some spilled salt beneath a conveyor belt transfer. While pushing a shovel through the salt, they felt a sharp pain in their lower back. The pain made it difficult to maneuver and the employee decided they needed to seek medical attention.
The designated person called for the cage to pick the people up from the work deck.

While entering the basket of a powder truck the employee reached over with left hand to close the lift arm.
