All MSHA-reportable accidents at Silver Opportunity Partners LLC operations in 2025. Fatalities appear first.
The electric motor for the pump on the 1700 level lost one leg of the 3 phases. This caused the remaining two legs to heat up because they were drawing more amperage. The varnish on the coils and insulation started to smoke as a result of the motor heating up.
EE was installing air header onto existing HDPE pipe valve. EE tightened the vic between the valve and header. EE realized the header needed to be rotated so EE used the impact and started to loosen the bolt. EE inadvertently loosened the bolt on the charged side of the valve causing the header to break free from the vic.
EE was swamping on the back of the track lowboy that was loaded with an electrical cabinet. The cabinet came in contact with the lockbox for the portal gate causing the lowboy to come to a sudden stop. The stop caused the employee to come in contact with the electrical cabinet.
