四通矿井下移动抽采系统研究

本科论文AbstractChina's coal mine gas mining industry has a long history.Coal mine resources arenon-renewable resources.With the use and development of coal mine resources,the miningprocess is very difficult and prone to safety accidents.The first task of mining is gasextraction.China has used many methods for gas drainage,so that we can play in many ways.Gas drainage is very important for coal mining enterprises.The hidden danger of gasdrainage is also great.If we cannot scientifically and reasonably extract gas,safety accidentswill easily occur.Coal mine gas is the natural enemy of coal mine safety production.It willnot only cause coal mine workers to harm human physical and mental health,but alsosuffocate death.At the same time,it will also cause gas and coal dust explosions,causingserious damage to the mine.Therefore,it is very important to effectively control gas andreasonably use gas as a resource for extraction.The gas extraction also requires a gasextraction method.In this design,the goaf cannula extraction and high gas drilling method areselected.Key words:Gas extraction;extraction method;safety
