A kind of fast sealing device and method

Abstract

The present invention relates to a fast plugging device and method. The device includes a folding board, a folding device, a traveling wheel, a control device and a power supply device. The folding board includes a movable folding board and a fixed folding board. The rotation is connected to both sides of the fixed folding display board. When the movable folding display board is rotated to the same plane as the fixed folding display board, the edge line of the movable folding display board and the fixed folding display board are spliced ​​into a complete rectangle; the traveling wheels are connected to the bottom of the fixed folding display board through an electric cylinder; The display device and the electric cylinder are electrically connected with the single-chip electromechanical device, and a control panel is arranged on the surface of the fixed folding display board, which is connected with the single-chip computer; the power supply device supplies power to the device. The invention divides the goaf and the mining area into two parts reasonably by means of partition, so as to prevent gas explosion accidents in the mining area from flowing to the goaf, and at the same time, prevent oxygen from flowing to the goaf to support combustion of residual coal. Avoid the potential safety hazards caused by the burning of residual coal.

Description

technical field [0001] The invention belongs to the technical field of coal mine production safety, and in particular relates to a quick plugging device and method. Background technique [0002] At present, my country's coal reserves are large and the output is high. At the same time, coal, as the most important part of my country's energy structure, has a huge amount of mining every year. Due to the large amount of mining, many coal mines will form gobs. The current mining technology at home and abroad is limited. , the mining capacity of the equipment cannot fully mine all the coal seams, there is inevitably residual coal in many goafs, and the production conditions of coal mines are limited, the goafs are often only shelved, and the residual coal in the goafs has the risk of spontaneous combustion If there is no partition between the roadway in the underground mining area of ​​the coal mine and the goaf, if the gas in the roadway in the underground mining area of ​​the coal...

[0002] At present, my country's coal reserves are large and the output is high. At the same time, coal, as the most important part of my country's energy structure, has a huge amount of mining every year. Due to the large amount of mining, many coal mines will form gobs. The current mining technology at home and abroad is limited. , the mining capacity of the equipment cannot fully mine all the coal seams, there is inevitably residual coal in many goafs, and the production conditions of coal mines are limited, the goafs are often only shelved, and the residual coal in the goafs has the risk of spontaneous combustion If there is no partition between the roadway in the underground mining area of ​​the coal mine and the goaf, if the gas in the roadway in the underground mining area of ​​the coal mine flows to the goaf and contacts with the residual coal spontaneously ignited in the goaf, a coal mine gas explosion will easily occur. It brings great harm to the safety of coal mine production. Therefore, there is an urgent need for a device that can quickly block the goaf and effectively isolate the goaf from the area where the coal mining is in progress when the residual coal in the goaf spontaneously ignites. Prevent gas from escaping to the goaf, resulting in gas explosion
