The invention discloses a device for establishing an emergency rescue channel in collapsed bodies of a coal mine roadway. The device for establishing the emergency rescue channel in the collapsed bodies of the coal mine roadway comprises a left baffle, a rear baffle, an upper baffle, a jack, protruding baffles, fixing pins and connecting hinges, wherein the protruding baffles are inserted into both ends of the left baffle, both ends of the rear baffle and both ends of the upper baffle correspondingly and fixed by the fixing pins when the protruding baffles protrude; the protruding baffles arranged at the upper ends of the left baffle and a right baffle are connected with the protruding baffles arranged at both ends of the upper baffle through the connection hinges correspondingly; the left baffle is composed of a left front baffle and a left rear baffle, and the left front baffle is connected with the left rear baffle through the jack; the right baffle is composed of a right front baffle and a right rear baffle, and the right front baffle is connected with the right rear baffle through the jack; and the upper baffle is composed of an upper front baffle and an upper rear baffle, and the upper front baffle is connected with the upper rear baffle through the jack. The device can rapidly establish the emergency rescue channel in the collapsed bodies of the coal mine roadway for saving the lives of trapped people after a coal mine disaster.
Description
technical field [0001] The invention belongs to the technical field of coal mine safety production emergency rescue, and relates to a device for establishing an emergency rescue passage in a coal mine roadway across a falling body. Background technique [0002] The number of casualties caused by coal mine accidents in our country is second only to traffic accidents. Coal mine safety production not only affects the healthy development of the coal industry, but also affects the harmony and stability of society. Emergency rescue has always been considered the last line of defense to save the lives of trapped people after coal mine disasters occur. On the premise of ensuring the safety of rescuers, fast and effective rescue work is a new concept of emergency rescue today. Among all kinds of disasters in coal mines, gas (coal dust) explosion, coal and gas outburst, and rock burst are considered to be the most disaster-causing disasters. These disasters will cause varying degre...
