Abstract
When accidents such as inrush of water, fire or falling happened, workers were trapped in a difficult position and rescue team could not approach. How to get through the isolation layer quickly and carry out emergency rescue is the main priority of the rescue team, which have great significance to reduce accident death rate and economic losses. In this paper, we analyze the application status of rapid drilling technology at home and abroad in coal mine accident rescue. When the drilling conditions encountered broken, fractured and other complex issues, we propose the air DTH reverse circulation drilling technology used in mine emergency rescue is feasible.
