Problems solved by technology
[0003] When a mine flood occurs, people often take refuge on the top of the uphill or uphill-shaped working face. After flooding, these refuge spaces form "bubbles". At present, the general rescue method is to drill holes, but after the holes are opened, the air Leaked under the action of water pressure, resulting in secondary flooding of the refuge space, resulting in death and affecting the rescue of mine disasters

Description
technical field [0001] The application relates to a rescue ventilation device, in particular to a rescue ventilation device suitable for mines, and belongs to the technical field of mine safety. Background technique [0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form the underground coal mine production system. Sometimes the inclined shafts, vertical shafts, and adits in the underground development of mines are also called mines. According to different mine production capacities, my country divides mines into three types: large, medium and small, namely the well type, the relationship between mine production capacity and service life, which is essentially the relationship between mine production capacity and mine reserves, and is directly related to the total cost of coal per ton. Within the scope of the mine field, the mine reserves are fixed, the larger the well type, the shorter the service life; the smaller the w...
