Abstract
The invention discloses a temporary and rapid sealing device and method for a mine disaster area. The temporary and rapid sealing device comprises a friction resistant air bag, a high pressure vessel,an air pressure foam generator and two sets of isolation mechanisms. The isolation mechanisms comprise vertical hydraulic isolators and horizontal hydraulic isolators. The temporary and rapid sealingmethod comprises the steps that (1) the positions of the isolation mechanisms are selected; (2) the isolation mechanisms are installed; (3) the suitable friction resistant air bag is selected and thefriction resistant air bag is pre-installed; (4) the disaster area is sealed by the friction resistant air bag; and (5) buffering protection of the friction resistant air bag and the isolation mechanisms is performed. The temporary and rapid sealing device and method for the mine disaster area utilize the two isolation mechanisms to clamp the friction resistant air bag filled with foam, bag-typefilling conformed with the section of a mine roadway is formed by the friction resistant air bag under the action of the foam, various shapes of roadways can be adopted and a good sealing property isachieved, the accident chain reaction can be quickly and effectively cut off, and the spread of toxic and harmful gas is avoided.
Description
technical field [0001] The invention belongs to the technical field of temporary sealing of catastrophic areas, and in particular relates to a temporary rapid sealing device and method for a catastrophic area of a mine. Background technique [0002] In recent years, with the integration of national coal mines, comprehensive mechanization has also been applied on a large scale underground, and the possibility and destructiveness of underground accidents have also increased to varying degrees, especially in gas explosions, coal dust explosions, and underground fires. When an explosion or fire accident occurs underground in a coal mine, it is necessary to quickly determine the area of the fire or explosion, find the relevant roadway where it is located, and use relevant blocking measures to cut off the air flow in the area to achieve the purpose of controlling the oxygen supply in the disaster area. In the existing temporary airtight devices, the conventional method is to u...
