Mine catastrophic areaquick sealing device and method

Abstract

The invention discloses a mine catastrophic areaquick sealing device and method. The mine catastrophic areaquick sealing devicecomprises a catastrophic information acquisition module and a plurality of combined airbag mechanisms;the method comprises the steps that 1, the sizes of the combined airbag mechanisms are determined; 2, the mine catastrophic areaquick sealing deviceis mounted; 3,data collection is conducted; 4, the combined airbag mechanisms are inflated; 5, the combined airbag mechanisms are reinflated; and 6, the combined airbag mechanisms are recovered. According to the mine catastrophic areaquick sealing device and method, multiple sets of the combined airbag mechanisms are used for sealinga roadway in the catastrophic area, microcontrollers in the combined airbag mechanisms receive data from the catastrophic information acquisition module and an air pressure detection module to control the quick inflation of a main airbag and an auxiliary airbag to achieve quick sealing of the roadway, chain reaction of catastrophic accidents is cut off in time to ensure safety of personnel and property to the greatest extent,at the same time, the traditional hydraulic pillar supportmethod is discarded, the combined airbag mechanismsare fixed and supported by connection buckles, the using cost isgreatly saved,and extremely high practical value is achieved.

Description

technical field [0001] The invention belongs to the technical field of rapid sealing of mine catastrophic areas, and in particular relates to a rapid sealing device and method for mine catastrophic areas. Background technique [0002] In recent years, with the integration of coal in the country, 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. Fires, explosions, poisonous gas leakage, and water penetration in underground coal mines have occurred. In the event of a catastrophic accident, the method of filling the airbag to seal it can be used to block the chain reaction of the accident. However, compared with the previous technology, the impact resistance of the airbag seal is too weak in the harsh environment of the catastrophic area, and the sealing effect is poor, and the hydraulic props are mostly used for the props of the airbags. The co...

However, compared with the previous technology, the impact resistance of the airbag seal is too weak in the harsh environment of the catastrophic area, and the sealing effect is poor, and the hydraulic props are mostly used for the props of the airbags. The hydraulic props are high in cost and heavy, and it is difficult to quickly Support the airbag

At present, the inflation of the air bag in the underground is connected with an external inflation pipeline, using high-pressure gas cylinders to inflate, the circuit layout is complicated and easily affected by the environment, and the gas leakage of the inflation pipeline is prone to occur; Or the influence of the harsh environment causes the gas in the air bag to leak, thus affecting its airtightness, which cannot well guarantee the safety of underground personnel and property safety
