本科论文AbstractGas drainage is one of the fundamental ways to prevent and control gas disasters.Anefficient gas drainage system is a prerequisite for ensuring the drainage effect.At present,allmines in China have gas extraction systems,so it is necessary to design a complete andeffective underground mobile extraction system for mines.Based on the overview of ShenMining,this paper designed and researched a complete set of underground mobile extractionsystem,combined with the actual situation of Shen Mining and the production and operationrules,established a complete set of underground mobile extraction system to effectively solvethe coal mine The gas extraction is of great significance to ensure the safe production of thecoal mine.Through the detection of the actual gas content of No.2 coal seam in Shen Coal Industry,the coal mine is a low-gas coal mine.When the No.2 coal seam is mined,the gas in the coalmining face is dominated by the mining layer and the adjacent layers are supplemented.Theoccurrence rule of gas in Shen Mining Industry is the result of the combined action of geologyand geography.This design only considers the corner gas drainage in the working face,combined with the characteristics of the gas source endowed by the coal seam of Shen CoalIndustry,the drainage method of the goat intubation is mainly used in the corner of theworking face.A negative pressure zone allows the high-concentration gas accumulated in thisarea to be discharged from the drainage pipeline,reducing the diffusion of gas in this area tothe upper corner and preventing the accumulation of gas in the upper corner.By analyzing the gas extraction system of Shen Coal Mine,calculating the gas emissionof the mine and adopting effective gas extraction methods,it provided a feasible scheme forShenjiao Coal Industry,and also designed gas extraction for similar mines Provide a referencebasis.
