Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine safety equipment, in particular to a flameproof water shed. BACKGROUND

[0002] Generally, the explosion in the coal mine underground is generally divided into three categories: gas explosion, other gas explosion and coal dust explosion; the three types generally have the characteristics of wide distribution range of explosion source material, long energy release time, etc., once the explosion occurs, the flame acceleration phenomenon often occurs due to the effect of obstacle groups such as production equipment (such as coal machine, support, pump station, shift, etc.), chamber (machine nest, water nest, etc.) or pipe wall surface, the coupling effect of flame and pressure wave leads to the increase of disaster degree and action range. Especially, in the case that the combustible gas explosion propagation pipeline has a large length-diameter ratio, even the transition from deflagration to detonation may occur.

[0003] At present, the main mining method in China is underground mining, and the current coal mining technology often causes a large amount of coal dust to deposit on the surface of the roadway and equipment, so the gas and coal dust explosion often propagates along the underground roadway, chamber or mining working face, causing multiple continuous explosions, thereby rapidly threatening the adjacent working face, the entire mining area, and even the entire mine.

[0004] In order to timely, effectively and reliably control the explosion propagation disaster in a local range, the most commonly used method for preventing and isolating the coal dust explosion in the fully mechanized mining face in China is to set a flameproof water shed (or rock powder shed) in the fully mechanized mining crossheading, but the setting of the flameproof water shed has strict regulations, and the traditional setting method of the flameproof water shed is not only troublesome to set and remove, but also has safety hazards in the setting and removing process.

[0005] The existing explosion-proof water shed mainly has the following shortcomings: 1. Large installation and removal engineering quantity; the length of the crossheading of the modernized fully mechanized working face is generally more than 4000m, at least 3 crossheadings are arranged in each working face (more in high gas mines), and at least 4000 / 200*3=60 groups of explosion-proof water bags need to be installed and removed according to the above provisions; 2. High artificial economic cost; usually, at least 2 shifts are needed for a group of (5 people) workers to install a group of explosion-proof water sheds at a specific position, and at least 1.5 shifts are needed for a group of explosion-proof water sheds to be removed and recycled; 3. High economic loss caused by repeated disassembly and assembly of explosion-proof water bags; due to the influence of coal dust and the like, only 20% of the explosion-proof water bags can be reused after repeated disassembly and assembly; 4. High incidence of occupational diseases of related workers; the current explosion-proof water shed (including explosion-proof water bag) is basically installed by workers, the shed frame is fixed on the roof of the roadway first, then the explosion-proof water bags are hung one by one, and water is added to each water bag. Because it is a roof operation, even if the workers wear raincoats, their clothes will be soaked by the dripping water from the high altitude, and long-term operation will cause serious occupational diseases; 5. Safety accidents have occurred during the operation; in the current domestic coal industry, especially in the modernized fully mechanized mine, the height of the roadway is high, and the workers have to climb for a long time to install the explosion-proof water bags, which not only has high labor intensity, but also has high safety risks of high-altitude operation.
