Causes of extremely cold weather affecting mine power failure.

Power line failure, equipment failure, road traffic difficulties and other reasons.

1, power line failure: heavy snow weather is likely to lead to power line failure, such as disconnection and tower collapse. These failures will lead to power failure in the mine, which will not be able to operate the equipment normally and provide necessary power support such as lighting and heating, thus affecting the production activities of the mine.

2. Equipment failure: The heavy snow with low temperature and high humidity can easily lead to the failure of mining equipment. In extremely cold environment, mechanical equipment will encounter problems such as starting difficulties, poor lubrication and parts damage. These failures will lead to equipment downtime, and then affect the production capacity of the mine.

3. Road traffic difficulties: The heavy snow weather caused the roads to freeze and the snow increased, which hindered the transportation of the mine. The difficulty of road traffic will delay the transportation of materials including fuel and maintenance equipment, and then affect the normal production of mines.
