With the continuous improvement of mechanization level in coal mines and the increasing intensity of excavation, a lot of coal dust generated in mines has become a part of coal miningAn allProminent issues in production Therefore, it is urgent to improve measures to avoid coal dust blasting and isolate blasting communication in coal mines The water tank shed and rock powder shed currently used underground in coal mines are reliable explosion-proof measures But the initial investment for the sink shed is large, and it is prone to damage during transportation, And explosion-proof water bagDue to its low investment, simplicity, and ease of implementation, it has been used in mines to replace water tank sheds and rock powder sheds as auxiliary explosion-proof measures to limit the transmission of coal dust blasting.

Hanging standard for explosion-proof water bags

(1) The installation method of water bags in underground tunnels is suspended and arranged horizontally (i.e. the long side is perpendicular to the tunnel axis).

(2) The principle of the explosion-proof water bag device method is that when subjected to the explosion-proof impact force, the water in the water bag is easily rippled out

(3) The sum of the width of the roadway occupied by each row of explosion-proof water bags and the share of the largest width of the roadway: the net cross-sectional area of the roadway is less than 10m2, at least 35%; the net cross-sectional area of the roadway is 10-12m2, at least 50%; the net cross-sectional area of the roadway is less than 12m2, at least 65%.

(4) The gap between two water bags in the same drainage shed is 10cm-1.2m; The sum of the gap between water bags and the gap between water bags and the roadway shall not exceed 1 5m. In special circumstances, it should not exceed 1.8m

(5) The vertical distance between the outer edge of the explosion-proof water bag and the two sides of the alley and the top beam shall not be less than 100 mm, and the vertical distance from the bottom of the water bag to the top plate shall not be less than 1.6 meters. If the top beam is greater than 1.6 meters, a water bag must be added above the water bag. The vertical distance between the bottom of the water bag and the entire roadway track surface shall not be less than 12 meters and not less than 1.8 meters of the roadway height, and the water bag shall maintain the same height.

(6) When using the easy to detach placement method for explosion-proof water bags, the hook orientation should be aligned, and each pair of hooks should be placed facing each other (hook tip to hook tip). Pull a round steel hook with a diameter of 4mm to 8mm, a hook angle of 60 "± 5 °, and a bent hook length of 25mm

(7) When hanging explosion-proof water bags in tunnels with both single track cranes and single track cranes, the explosion-proof water bags should be hung with hanging tags. The single track crane and the single track crane should be placed below the waterproof bag, and the distance between the air crane and the single track crane unloading board should not be less than 70cm (the explosion-proof rod is 10cm from the top plate, the explosion-proof hook is 27cm long, and the explosion-proof water bag is 30cm long).

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.

　　For over thirty years, the explosion-proof water sheds in most mines have been replaced by explosion-proof water bags. We hope that coal mining enterprises can strengthen the installation and protection of explosion-proof water bags in coal mines, and also advocate for coal minesAn allRegulatory and supervisory departments should strengthen inspections and urging to ensure that explosion-proof water bags can fully play their role in coal mines in case of incidents.
