[0002] Gas is a flammable gas that is widely used in homes and industries, but it also needs to be used with caution to prevent accidents. When dealing with high-gas or protruding mine gas, top drilling and blowholes are common. During blowholes, high-concentration gas and coal powder gush out of the drill hole in large quantities. As the concentration of the gas gushing out increases, the coal powder generates heat due to friction with external objects during the spraying process, which may lead to gas explosions and other safety-threatening accidents.
