Underground coal mine tunnel type emergency rescue channel system

Abstract

The invention relates to the technical field of coal mine emergency rescue, in particular to an underground coal mine tunnel type emergency rescue channel system. The underground coal mine tunnel type emergency rescue channel system comprises an emergency rescue channel, a pressure fan, an air supply barrel tape and a control chamber. The emergency rescue channel is arranged on one side of a roadway in the extending direction of an underground coal mine tunnel. The control chamber is arranged on the earth's surface, and a controller is arranged in the control chamber. A compressed air port is further formed in the upper portion of the side wall of the emergency rescue channel. One end of the air supply barrel tape is used for being communicated with the pressure fan in the control chamber, the other end of the air supply barrel tape is communicated with the compressed air port, and the pressure fan is electrically connected with the controller. When gas and coal outburst, gas explosion, fire disaster, water permeating, collapse and other dangerous cases occur in the tunnel, the pressure fan delivers ground air into the tunnel through the air supply barrel tape. Accordingly, the dangerous cases in the tunnel is relieved, the rescue difficulty of rescuers is reduced, and further the rescuers can conveniently enter the tunnel to search and rescue underground trapped persons in the roadway.

Description

technical field [0001] The invention relates to the technical field of coal mine emergency rescue, in particular to a coal mine underground tunnel type emergency rescue channel system. Background technique [0002] Coal is one of the essential energy sources in human daily life and production. Casualties in coal mine accidents in China account for 70% of the world's coal mine casualties, and accidents such as gas explosions, coal and gas outbursts, fires, water inrush, and landslides are prone to occur. [0003] When a mining accident occurs, due to the lack of understanding of the degree of damage, the severity of the disaster, and the harsh environment of the catastrophe in the roadway, the emergency rescue is blocked, the progress of the emergency rescue is slow, and sometimes it is caused by unscientific and irrational emergency rescue. Secondary disasters cause greater property losses and casualties of emergency rescue personnel. Traditional emergency rescue methods con...
