Explosion proof water bag is a device container used underground in coal mines. The water bag shed composed according to the device skill requirements can help block the spread of gas and coal dust explosions, reducing the losses caused by disasters. When gas or coal dust is blasted, it can have the effect of spacing flames, reducing the temperature of blasting gas, weakening shock waves, and narrowing the disaster area.

Explosion proof water bag standard:

1、 Explosion proof water bags are divided into main explosion-proof water bags and auxiliary explosion-proof water bags, and are further divided into centralized explosion-proof water bags and dispersed explosion-proof water bags according to their placement methods.

2、 The water volume of the explosion-proof water bag

Calculated based on the cross-sectional area of the roadway: the water volume of the main explosion-proof water bag shall not be less than 400L/m2, and the water volume of the auxiliary explosion-proof water bag shall not be less than 200L/m2

　　3、 Positioning of explosion-proof water bags in tunnels

(1) Explosion proof water bags should be installed in straight tunnels

(2) The interval between explosion-proof water bags at roadway intersections and turns must be maintained at 50m-75m, and the interval between explosion-proof water bags and air doors must be greater than 25m

(3) The distance between the burst water bag in the first compartment and the working surface should be maintained at 60-200mm

(4) Multiple sets of explosion-proof devices should be installed in the winding channel where auxiliary explosion-proof water bags should be installed, with intervals of no more than 200m between each set

　　4、 Interval between rows of explosion-proof water bags and length of explosion-proof water bags

The distance between water bags is 1.2-3.0 meters, and the length of the main explosion-proof equipment is not less than 30 meters, while the length of the auxiliary explosion-proof equipment is not less than 20 meters.

All employees of our company, with full enthusiasm, provide you withexcellentOur products and enthusiastic service will work together with you to seek development and create a better future.

The explosion-proof water shed or water bag of coal mine roadway equipment is based on the principle that the shock wave generated during coal dust and gas blasting in coal mines atomizes water and absorbs flame energy, thereby suppressing the propagation of blasting flames and limiting the expansion of blasting scaleAn allFacilities. Therefore, it is hoped that coal mining enterprises can strengthen the installation and maintenance of explosion-proof water bags in coal mines, and it is also recommended that coal minesAn allRegulatory and supervisory departments should strengthen inspections and urging to ensure that explosion-proof water bags can fully play their role in the event of accidents in coal mines.
