Mine Rescue Operations: Navigating Hazardous Conditions

Flashcards based on lecture notes about mine rescue operations, focusing on navigating through hazardous conditions such as smoke, ventilation controls, and water.

In conditions of very poor visibility due to smoke, you may need to keep in constant with a rail, a compressed air or water line, or the side.

When smoke is very dense, maintain physical contact with a rail, compressed air or water line, or the side to 'feel' your way along.

Before going through a , the team should first try to determine what conditions exist on the other side.

Before going through a ventilation control, determine conditions on the other side by feeling the bulkhead or door for heat and looking for smoke.

Before opening doors or bulkheads with unknown conditions, erect a outside it to provide an air lock.

Erect a temporary bulkhead outside any bulkhead or door beyond which conditions are not definitely known, to provide an air lock.

When your team encounters water during exploration, the will usually decide how to deal with the problem.

The command center usually decides how to deal with water encountered during exploration.

It's recommended that you don't travel through water that is more than .

It is recommended not to travel through water that is more than knee deep.

If you have , and gas conditions in the area permit, your team may pump the water out.

Consider pumping water out if you have pumping equipment and gas conditions permit.

The water itself may contain hazardous which can be released into the atmosphere as the pumping operation proceeds.

The water itself may contain hazardous water-soluble gases which can be released into the 'good' atmosphere as the pumping operation proceeds.

In mines with , the pump itself should be set up in an area with good air and have suction lines.

In mines with explosive gases, the pump should be set up in an area with good air and have non-conducting suction lines.

Crawling or climbing tires the team, so you should do it only when .

Crawling and climbing tires the team, so do it only when absolutely necessary.
