Application of Gas Protection Device in High Gas Mine

摘要

Aiming at the characteristics of high gas coal seam hosting and the problem in the process of coal gas control, this article mainly focus on the research of the gas drainage technology in the goaf and the coupling characteristics with the explosion proof device. First of all, it describes the comprehensive gas drainage technology in mine, then put forward a new gas control device, and developed the corresponding supporting equipment and materials, which applied in mine, results show that the technology can solve the gas drainage tube's hidden trouble of electrostatic burst, ensure the coal mine's continuous safety production.
