Research On Hongmiao Coal Seam Gas Foundation Parameters And Gas Emission Law

Gas emission is the important factors of safety production in coal mine. According to thesituation of coal mine gas accident.Do not have sufficient gas geological work.Gas deposit law isunclear.Can’t develop effective prevention strategies is the root causes of the disaster.Gas emission is the important factors of safety production in coal mine. According to thesituation of coal mine gas accident.Do not have sufficient gas geological work.Gas deposit law isunclear.Can not develop effective prevention strategies is the root causes of the disaster.For the5-3S of six districts a mechanized mining face gas emission rate is increasing, the gas is oftenoverrun phenomenon.Studying on theory and experimental of the Hong Miao’s basic gasparameter.Sub-source to predict the six districts5-3S mechanized mining face and the sixDistrict5-1N Coal Lane Tunneling Face Gas Emission.Get the gas emission predicted value andthe source of gas emission. Using the on-site test, we research the rules of gas pouring out from5-3S fully mechanized caving face in variations in atmospheric pressure.Determine Hongmiaomine six5-3is barely drainage or difficult pumping coal seam.Mechanized mining face gasemission predictive value is2.62m3/min.Goaf gas emission accounts for mechanized miningface Emission ratio is56.9%,Goaf gas drainage is the focus of the gas control.Gas emission isinversely proportional to the amount of ground atmospheric pressure.The impact of changes inatmospheric pressure gas emission can not be ignored. Identify and implement the solutionstechnical of ventilation to dilute and goaf pipe drainage, proposed drainage system layout,equipment selection and process parameters.Could importantly contribution to the high yield andefficiency,harmony mine construction.
