Anti spray hole device

Product Introduction
The anti spray hole device, based on the principle of "taper expansion" sealing and the drainage tee device, can controllably collect the gas containing coal sprayed during the drilling process of high gas and coal and gas outburst mines into a specially sealed container, avoiding injuries and gas exceeding safety accidents caused by gas spray holes, while also reducing construction dust and improving occupational environmental hygiene level. It is one of the essential auxiliary equipment for modern production mine drilling construction.
Performance characteristics
Develop a sealing device based on the "taper expansion" sealing technology, which can be reused and orderly introduce gas containing coal into the drainage three-way device;
The device is made of stainless steel processing, with exquisite appearance, easy installation and transportation, and equipped with extraction port, discharge port, discharge door, etc. The main body of the equipment has good sealing and practicality;
Customized sealing equipment of corresponding specifications can be made according to the user's underground construction site, achieving the practical purpose of adapting to local conditions;
After drilling, the anti spray hole task can still be carried out to reduce gas exceedance accidents in the drilling site;
