本科论文AbstractChina's annual coal production is about half of the world's total coal production and isthe world's largest coal producer.China is currently at a high-speed stage of socialdevelopment,and its dependence on fossil energy such as coal is becoming stronger andstronger,In addition,coal is the most important fossil energy in China,and its reserves areextremely rich.It has a high strategic position in the national energy structure.Itsconsumption proportion is about 70%in recent years.It can be seen that in a long period oftime in the future,China The main energy source will still be coal.However,looking atChina's overall development situation,China's geological conditions are diverse and complex,and industrialization has led to a significant increase in coal demand.Therefore,thecontradiction between production and development affects the national economy and socialsecurity.In recent years,the coal mine industry has developed rapidly,gas emission has increased,and coal mine safety has been valued.Many coal mines in China have various dangerousconditions such as gas outburst during mining,so for the safety and effectiveness of coalmining,gas extraction has become an important part,especially the mining of high gas coalseams,and gas Gas extraction can also increase the utilization rate of gas and make a greatcontribution to environmental protection.Therefore,in order to produce safely,we need toestablish a complete and efficient gas extraction system.Key words:coal seam:high gas mine;gas gushing:gas drainage
