Research on the Comprehensive Control Technology about Gas in the Large Mining Height and Extended Mining Face for the High Gas Mine

Abstract:

The paper describes the three-tier stereo comprehensive management gas model for the mining height and extended mining face in the high gas mine. The model consists of gas drainage with surface drilling, progressive and shielding gas drainage with 1000m drilling machine from underground and so on. The measures make it easy to realize the combination of surface fracturing and gas extraction, establish the model of cooperation methane drainage from the surface and underground. Meanwhile, the ventilation type, three incoming-air gateways and two returning-air gateways, is used in the mining face. It can effectively avoid exceeding gas in the upper corner of mining face. It can guarantee safe and high-efficient mining. The green mining technology for coal and gas for simultaneous extraction is easily realized. It has important guiding value for mine gas management at similar conditions.
