What is the practical function of explosion-proof water bags? Why can explosion-proof water bags prevent explosions? When gas explosion occurs, the water bag is torn and detached by the impact, forming a long and dense water mist belt, which can effectively isolate the transmission of gas and coal dust explosion. The water bag material is made of water bag cloth that complies with the industry standard MTl13-1995 "Full functional Inspection Specification for Non metallic (Polymer) Products Used in Coal Mines". All indicators of the explosion-proof water bag must meet the skill requirements of the industry standard MTl57-1996 "General Skill Conditions for Explosion proof Water Tanks and Bags Used in Coal Mines".

1. Installation location of explosion-proof water bag

⑴ Main location for installing blast shelters: the main air intake and return tunnels connected to the mine shaft on both sides of the mine; Centralized transportation lanes and return air lanes between adjacent mining areas; Transport stone gates and return air stone gates between adjacent coal seams.

⑵ Auxiliary explosion-proof shed installation location: coal mining face inlet and return airway; Coal roadway and semi coal roadway excavation face; The roadway connected to the coal bunker; Other tunnels with independent ventilation and coal dust hazards.

2. Installation requirements for explosion-proof water bags

⑴ The main explosion-proof water shed includesBi wants toComposed of water bags larger than 40L each, the water volume should be fullfoot400L/m2。

⑵ The main explosion-proof water shed includesBi wants toCentralized device, with a spacing of 1.2-3m between rows, and a length of no less than 30m for the shed area. The gap between the water shed and the top plate should be no less than 100mm, and the distance from the rail surface should be no less than 1.8m, with a consistent height.

The centralized device for assisting explosion-proof equipment should have a water volume of 200L/m2, with a spacing of 1.2-3m between water sheds and a length of no less than 20m in the shed area. The first row of water sheds should be 60-200m away from the working surface,headThe distance between the explosion-proof water shed and the working surface isBi wants toAdhere to a distance of 60m to 200m, and multiple sets of water sheds should be installed in the roadway where auxiliary explosion-proof sheds should be installed, with intervals of no more than 200 meters between each set.. The water volume of the decentralized device shall be calculated based on the volume of the roadway space occupied by the shed area, and shall not be less than 1.2L/m3. The length of the shed area shall not be less than 120m, and the first row of water sheds shall be 30-60m away from the working face. The distance between the water shed and the roof and the gap between the two sides shall not be less than 100mm, and the height shall be consistent.

⑷ Explosion proof equipment hanging. The total gap between the water bags in each row and the gap between the water bags and the two sides, as well as the distance from the bottom of the water bags to the top plate, shall not exceed 1.5m.
