Explosion-proof water bag and explosion-proof water tank for coal mines are produced in strict accordance with standards High-quality products that have been inspected and inspected, have the functions of flame retardant, anti-static, good bearing capacity, no leakage, and easy to install. Explosion-proof water bags and explosion-proof water tanks are reliable products that can effectively prevent the spread of combustible gas and coal dust explosions underground in coal mines. Complete specifications.

Product Description

The explosion-proof water bag for mining is an installation container used in coal mines. The water bag shed formed according to the installation technical requirements can effectively isolate gas and coal dust. Propagation of Explosion The material used to make the water bag has safety properties such as flame retardant and anti-static.
1. Technical Requirements

Water bags and water tanks should comply with the provisions of this standard, and should be manufactured according to approved drawings and documents according to prescribed procedures. Outsourced materials should have certificates of quality and can only be used after passing the inspection.

The specifications and dimensions of water bags and water tanks should comply with the requirements in the table, and the actual water capacity must not be less than the nominal volume.

Water bag






















The water distribution characteristics should meet the following requirements

The explosion pressure (expressed as static pressure) required for the water tank to break shall not be greater than the explosion pressure (expressed as static pressure) required for the action of the water bag and shall not be greater than< br/>
. The action time to form the optimal water mist shall not be greater than

. The optimal water mist duration shall not be less than for the water tank and shall not be less than for the water bag

. The optimal water mist dispersion length shall not be less than

, the optimal water mist dispersion width shall not be less than

, and the optimal water mist dispersion height shall not be less than.

The explosion-proof performance should meet the following requirements. Counting from the explosion source, the explosion flame shall not exceed.
2. Structure The water bag is in the shape of a long trough with a semi-circular bottom and the seams are firmly bonded and the surface is neat and smooth, as shown in the picture. The water tank is rectangular and trapezoidal, formed in one step and has a smooth surface, as shown in the picture.

3. How to use

Water shed water Quantity

Explosion-proof water bag (tank) sheds are divided into centralized and decentralized types (depending on the layout).

The water consumption of the centralized water bag (trough) shed is calculated according to the type of tunnel section. The main water shed is not less than the auxiliary water shed and is not less than/

Decentralized water tank ( The amount of water in the bag) shed shall be calculated based on the volume of the lane space occupied by the shed area and shall not be less than . In straight tunnels

, at the intersection of the water bag (trough) shed and the tunnel, the distance at the turns should be maintained, and the distance from the damper must be greater than

, and the first row is concentrated The distance between the water sheds and the working surface must be maintained, and the distance between the first row of distributed water sheds and the working surface must be maintained.

Multiple groups of water sheds should be set up in the tunnels where auxiliary explosion-proof water sheds should be installed. The spacing between each group is not greater than

. The distance between rows of water sheds is the same as the length of the water shed area

. The distance between rows of centralized water sheds is that of decentralized sheds scattered along the lane. layout, the distance between the two water bag (tank) groups is

The length of the centralized main water shed is not less than, the length of the centralized auxiliary shed is not less than, and the length of the decentralized shed is not less than Less than.
4. Installation method

The installation method of the water bag (trough) shed can be hanging type or top-supporting type, or a hybrid type can be used. The principle is that when it is subject to the impact of an explosion, The layout where water is easy to spill out should comply with the following regulations

When the section is <, %

When the section is <, %

When the section is <, %

In the formula, the number of water bags (troughs) on the row of sheds, the width of the windward section of the water shed, the width of the horizontal tunnel where the water shed is located

, the gap between the water tanks (bags) and the water tank The sum of the gaps between (bags) and brackets or tunnel walls shall not be greater than the limit. The gap between two water bags (troughs) shall not be greater than the distance between the edge of the water bag (trough) and the tunnel wall, bracket, roof, or structure. Not less than the distance from the bottom of the water tank (bag) to the roof beam. If it is larger, an additional water bag (trough) must be added above the tank. height. When the roof needs to be raised, the tunnel section in the water shed area should be consistent with the tunnel sections at the front and rear.

Hold water bags (troughs). The hook positions should be aligned, arranged facing each other, and arranged in rows. The round steel, the hook angle is degrees, and the hook is changed.
5. Management and precautions for the water tank (bag) shed

The water bag (trough) must always be kept intact and the specified amount of water is required. The upper edge must be horizontal to meet the design requirements.

Inspection every half time

The water bag (tank) shed is declared to be used as auxiliary explosion proof.
6. Packaging, transportation and storage

Product packaging should comply with the relevant regulations for railway and road transportation (only one water bag, packed in a woven bag).

During transportation, the water bag should be protected from mechanical impact and friction, as well as sunlight and rain.

The products should be stored in a well-ventilated warehouse. The stacking should not be too high to avoid affecting the quality of use. It is forbidden to come into contact with substances that damage the quality of rubber and plastic. Avoid direct sunlight and rain. The storage temperature should be between ℃ and ℃, relative temperature ﹪, and away from the heat source.

The explosion-proof water bag must have the function of flame retardant or flame retardant and antistatic, and it must have the bearing capacity to carry the corresponding volume of water, and there must be no leakage.

According to different requirements, water bags with different volume specifications are made, and corresponding wind buckles are made on both sides to facilitate the installation and replacement of shaped movable hooks in the water bag shed. Iron bars of corresponding specifications need to be inserted on both sides of the water bag to increase the carrying capacity of the water bag.

The water bag must be tightened and hung securely, and the force must be evenly distributed. Every buckle must be hung and must not be left behind.
