 Product description: 
 Mine explosion-proof water bag is used for the installation of underground coal mine container, press install the technical requirements of the water bag shed can effectively cut off from gas and coal dust explosion propagation; production of the material of the water bag with a flame retardant, anti-static safety performance . 
 First, the technical requirements 
 1, water bags, the sink should be consistent with the provisions of this standard and should be required to the procedures for approval of drawings and documents manufacturing. Purchased materials should have the certificate to use after passing inspection. 
 2, the water bag, the dimensions of the sink should be consistent with the requirements of Table 1, the actual water capacity of not less than the nominal volume.

 The water distribution characteristics should meet the following requirements: 
 (1), broken sink required for explosion pressure (static pressure) shall not be greater than 16 kPa; Hydration action required for explosion pressure (static pressure) shall not be greater than 12kPa; 
 (2), form the best mist action shall not be greater than 150ms; 
 (3), best mist duration: the sink shall not be less than 250ms, the water bag shall not be less than 160ms; 
 (4), the best mist scattered the length of not less than 5m; 
 (5), the best mist dispersion width of not less than 3.5m; 
 (6), best mist scattered height of not less than 3m. 
 The explosion-proof performance should meet the following requirements: counting from the explosion source, the explosion flame shall not exceed 140m. 
 Second, the structure: YS water bag, a long trough, the bottom was semi - circular suture firmly bonded surface neat and smooth, as shown in Figure 1; YS sink, rectangular trapezoidal, forming a smooth surface, as shown in Figure 2. 
 Main: Hydration Flameproof explosion-proof water bag 


 Third, the use of 
 1, the water shed water consumption: 
 Flameproof water bag (slot) shelf is divided into centralized and distributed (according to the layout may be). 
 Centralized water bag (groove) shed water consumption by roadway section calculation, the main water shed of not less than 400L / m 2, the auxiliary water shed of not less than 200L / m 2; 
 Distributed sink (bags) shed water shelf area occupied Road Lane space volume calculation; less than 1.2L / m 3. 
 2, the location of the boron settings: 
 (1), the water bag (slot) shed should be set in the straight roadway; 
 (2), shed (slot) of the water bag and roadway cross the intersection, turning at the distance should be maintained 50-70m, and the distance of the throttle must be greater than 25m; 
 (3), concentrated in the first row of the distance of the water shed and the face must maintain the 60-200m, the distance of the first row of the distributed water shed and the face must maintain 30-60m; 
 (4) should be located in the roadway should be set up auxiliary flameproof water shed water sheds, each group spacing of not greater than 200m; 
 3, the water shed row of the distance between the water-shed shed length: 
 (1), the distance between centralized water shed row of 1.2-3.0m, distributed sub-sheds scattered along the roadway layout, two water bags (tank) group spacing for 10-30m; 
 (2), the length of the shelf area of ??the centralized water shed is not less than 30m, centralized auxiliary shed length is not less than 20m, distributed the length of the shelf area is not less than 200m. 
 Fourth, the installation 
 A water bag (slot) shed installation: can be used hanging or prop type, but also can be mixed; principles are: by the explosion impact, water easily spilled; arrangement should meet the following requirements: 
 Section S <10m2, NB / L x 100> = 35% 
 Section S <10m2, NB / L x 100> = 50% 
 Section S <10m2, NB / L x 100> = 65% 
 N-row where the number of shed on the water bag (slot), B-water shed windward section width, L-water shed where the horizontal roadway width; 
 2, the gap between the sink (bags) and sink (bags) of the gap with stand or wall between Lane and shall not be greater than 1.5m, ban ultra 1.8m, the gap between the two water bags (tank) shall not distance not more than 1.2m, the water bag (groove) edge with Lane wall, the distance between the brackets, roof, structures not less than 0.1m, the bottom of the sink (bags) to the top beam of 1.6m, if greater than 1.6m must be in the water bag (groove) on top of an additional; 
 3, the track surface of the water shed away from the roadway of not less than 1.8m, should manage the uniform height of the need to pick the top, the water shed area roadway consistent with their before and after each 20m long roadway section; 
 Hanging water bag (groove), hook position arranged on the positive, opposite row hook 4-8mm round bar, hook angle of 60 ± 5 degrees, variable hook 25mm. 
 Sink (bags) shed management and precautions 
 To keep in good condition and the amount of water of hydration bladder (slot), and the upper edge of the required level of state, to meet the design requirements; 
 2, once every half friends; 
 3, the water bag (slot) shed declared for the use of secondary explosion-proof. 
 Six, packaging, transport and storage 
 1, the product packaging should be consistent with the railways, the relevant provisions of the road transport (water bag 100 a pack, using woven bags). 
 2, the water bag during transport to prevent mechanical shock and friction, avoid the sun, and rain. 
 3, the product should be stored in well-ventilated warehouse, stacking may not be too high, so as not to affect the quality, prohibiting contact with substances detrimental to the quality of rubber and plastic, to avoid direct sunlight, rain, warehousing temperature at -15 ℃ ~ 35 ℃ relative humidity between 40-80%, 1m outside and away from heat sources. 
 4, explosion-proof water bag must have a flame retardant or flame retardant anti-static function, and its need to have hosted the bearing capacity of the corresponding volume of water without leakage. 
 5, according to different requirements, the production volume specifications of the water bag, both sides of the production of the corresponding wind buckle for easy water bag shed the S-shaped hooks and installation and replacement. The water bag on both sides need to penetrate the iron bars of the corresponding specifications to increase the carrying capacity of the water bag. 
 6, the water bag must be taut hanging in prison, even by force, every buckle must be hung, not omission.
