Study On Yiyuan Mine's Gas Disaster Prevention Technology

The paper mainly determine gas basic parameters of YiYuan Mine,Single index method is used to predicte the mine gas danger. By the study of Rule of gas in YiYuan Mine, The paper shows that thickness of the overlying bedrock and roof and floor lithologic characters have an large effect on rule of gas. According to burying depth and content relations, gradient curve of gas content is showed, isopleths protracting sofeware surfer8.0 is used to draw the isoline map of NUM.15 coal seam. Which is printed through AutoCad2008. Gas the geological is showed.On the basis of the characteristic large gas content, according to surveys of gas in YiYuan Mine conducted over the last few years, amount of gas emission is estimated, it shows that the forecast results correspond to gas emission characteristic. Research of 150103 Face Gas Emission Features,and accord to yiyuan mine Special Gas Emission Law,Control measures on the question of gas drainage optimization is offered,the Mainly method is the optimization of gas drainage scheme,And identify high Roadway 150109 face's position.
