How many materials are there for hole sealers?

The capsule bag sealer is a kind of grouting bag sealer used for pumping gas in coal mines. Based on the theoretical basis of the "two walls and one injection" grouting sealing process under pressure, it is mainly suitable for sealing holes of various boreholes in coal mines. The grouting pump is used to fill the capsule bags at both ends of the hole sealer with slurry, expand at both ends, and then close the middle area of the two capsular bags, so as to achieve multi-layer sealing and ensure good results.

Boan hole sealer.

The capsule bag hole sealer is used for the plugging of coal seam boreholes, such as coal seam pressure measurement boreholes, rock roadway upward boreholes, downward boreholes, coal seam boreholes and other boreholes.

Working principle: connect the grouting pipe of the product with the grouting pump, and the sealing slurry enters the grouting pipe and the expansion bladder bag by the grouting pump, and the bladder expands, and the outer wall is sealed with the coal hole; When the grouting pressure reaches the harmony: the middle two blasting valves are blasted one after another.

The sealing solution seals the coal hole and the middle crack, and connects the gas pumping pipeline through the gas injection pipe to pump the gas.

Product features: 1. Sealing automation. The hole sealer is fed into the borehole, and only the grouting needs to be started to realize the automatic sealing of the whole borehole, which greatly reduces the labor intensity and improves the work efficiency.

2. Active support. After grouting the capsule, it can form an effective support for the borehole, so that a high-stress area can be formed around the borehole in the sealing section, so as to avoid continuous cracks and air leakage channels after the hole is sealed.

3. Pressure grouting. The pressurized grouting pressure reaches Zhaojiao, which can make the slurry hydraulic into the cracks of the borehole wall, close the cracks around the borehole, reduce its permeability, and play the role of blocking the initial air leakage channel.

4. The length is adjustable. The length of the sealer can be customized according to the actual length of the borehole downhole.

5. Advanced technology. The use of "two walls and one injection" pressure grouting sealing process, advanced technology, Henan Zhongqiang mining equipment technology sealing effect is good.

It can be divided according to the functional use: gas pumping, coal seam water injection, coal seam grouting, two walls and one injection.

According to the usage: self-expanding hole sealer, pneumatic hole sealer, water expansion hole sealer, water pressure hole sealer, plug-in hole sealer, water injection hole sealer, coal splitting system hole sealer, ultra-high pressure water injection hole sealer, bolt grouting hole sealer.

At present, the hole sealer technology is more advanced, including Jiahui Technology and other manufacturers.

The hole sealer mainly includes gas pumping hole sealer and coal seam water injection hole sealer.

The gas pumping hole sealer is mainly used for coal water injection and gas pumping.

Coal seam water injection sealer is used for coal water injection, dust reduction, coal pressure reduction, coal cracking, gas discharge, etc.

The hole sealer is a sealing device for the borehole of coalbed methane pumping and coal seam water injection.

The hole sealers include shallow hole plug-in spiral hole sealer, water injection hole sealer, mine hole sealer, coal seam water injection pumping hole sealer, and shallow hole plug-in push-up hole sealer.

Method steps.

Introduction to gas sealer products.

Gas hole sealer is a kind of sealing foam material, which is a modified polyurearate foam material specially developed for underground gas extraction and hole sealing. The gas sealing agent is composed of two components, A and B, and the two components are evenly mixed with a volume ratio of 1:1 during the sealing construction, and are injected into the specified depth of the coal mine gas borehole through a specific foam sealing automation device, and the on-site reaction foams and solidifies.

At the same time, according to the actual underground environment and specific construction needs, products with different foaming rates and polymerization reaction time can be provided.

How to use gas sealer.

1. There should be no flake oil stains in the sealed or blocked places, and the debris in the rock holes or coal holes should be cleaned as much as possible.

2. Accurately weigh the two groups (a, b) according to the required ratio (volume 1:1), and pour them with a special high-pressure grouting pump after mixing.

Features of gas sealer products.

1. The response time is fast, and it can be adjusted according to the actual underground environment and specific construction needs.

2. Non-toxic, tasteless, hydrolysis resistant, no environmental pollution.

3. The construction is simple, easy to operate, and the labor intensity is low.

4. The foam material has high strength and good toughness, which can minimize the influence of coal seam pressure on the sealing material tightness.

5. It has good adhesion to the gas extraction pipe and coal wall, and has excellent sealing performance.

Precautions for gas sealer.

1. The product should be stored in a closed container to avoid moisture absorption. During storage and transportation, it is forbidden to be exposed to sunlight, and it should be ventilated, protected from light and water. It is best to store it at room temperature (15-35) in a well-ventilated room and store it strictly; The decrease in temperature and the increase in the viscosity of the liquid components will affect the use effect and the performance of the final product.

2. This product does not belong to flammable liquids, ** products, oxidants, corrosive products, toxic products and radioactive hazards in the process of storage, transportation and transportation, and does not belong to hazardous products. Extinguishing can be done with carbon dioxide, foam or dry chemical fire extinguishers, or with a large amount of water spraying.

3. Be careful when operating, and slowly release the gas in the barrel when opening the lid to prevent raw materials from splashing into the first and eyes, and wear protective equipment if necessary. Once splashed in ** or in the eyes, it should be immediately rinsed with water for at least 15 minutes, **washed off with soapy water.

Generally, soluble materials, such as cement, polyurethane, inorganic materials, etc., are stirred and pneumatically pressed by the grouting pump through the grouting pipe and sent to the void.

It then gathers at the bladder of the grouting pipe, and then quickly coagulates.

1. Use: water injection and dust reduction in the coal body.

2. Function: 1. Water enters the coal body, releases part of the gas, and effectively reduces the gas content of the coal body.

2. After the effect of water injection is achieved, the dust can be reduced by more than 80%, the working environment of workers can be improved, and the gas can be eliminated.

3. Structure: The hole sealer is composed of a high-pressure rubber expansion hose, a pressure relief valve and a quick connector.

Fourth, technical parameters:

Sealing diameter: 30 120mm (can be processed according to user needs) Working pressure: 1 8MPa (can be processed according to user needs) Working flow: 4 tons of water per hour 5 tons. Hose expansion factor: 60%.

5. How to use and precautions:

1. It is quick and easy to use the coal seam water injection hole sealer. It is only necessary to communicate the waterway of the operation site with the hole sealer, and completely insert the hole sealing hole into the borehole, and under a certain pressure, the hole sealer hose expands to realize the hole sealing, and the water is injected to break the coal.

2. The coal seam water injection hole sealer can be used several times, and the pressure is removed after the water injection is completed, and the hole sealer can be restored to its original state and the hole sealer can be taken out.

3. It is strictly forbidden to operate under pressure for the plug-in and plug-in hole sealer and the first hole sealer.

4. No one is allowed to work in front of the hole sealer when it is working.

Hole sealing is an important technology in coal mine gas extraction boreholes, and the tightness of the borehole directly affects the pumping effect. 1. The hole sealing process includes cement mortar hole sealing method, wood wedge yellow mud hole sealing method, polyurethane foam hole sealing method (GSS hole sealing bag) 1 and synthetic resin and cement slurry pressure grouting (two walls and one injection).
