本科论文AbstractIt is coal company is located in SHA Province.It is approved to mine No.4 and No.15coal mines with a unit yield of 0.90mt/a.Reduce the amount of gas emission and ensure thesafety of production,the predecessor of coal mine gas drainage is the method of dealing withcoal mine gas summarized by a series of renewal and evolution of gas drainage.Based on the general situation of the mine and the calculation of the gas emission,ahigh-energy and effective mobile extraction system is designed.To some extent,it can alsomeet the market demand for coal and enterprises To survive.This paper mainly studies the gasdrainage system in dengjiazhuang mine,including gas emission,gas drainage and gasextraction pump selection.After the concrete drainage design improvement scheme,according to the drainagesystem,and combined with the actual gas drainage theory,the paper forecasts,and evaluatesthe effect of the gas drainage design scheme for the rainy gas drainage.The main evaluationindexes in front of the coal mining work can absorb the dissolved gas,the gas extraction rate(Including the gas drainage rate of the whole mine and the gas drainage rate in mining coalseam),Gas emission level in the mining face(gas discharge).Key Words:Gas quantity:Dividing source prediction method;Gas methods
