聚德矿井下移动抽采系统研究

本科论文AbstractIf the gas present under the mine is not handled properly in the production process,people can be poisoned or accidents such as gas explosions and fires can occur.Gas is anenergy resource that can be utilized if concentrations are controlled and its combustionproperties are utilized when handled properly.Therefore,in order to ensure that coal production is carried out safely,a safe andimplementable underground mobile extraction system is designed to ensure that the actualunderground needs can be met while minimizing economic costs.Draws on past gas extraction programs and combines them with the actual down-holeconditions at the Jude mine.By calculating and predicting the gas outflow down-hole,theappropriate pump type and piping for extraction is selected based on the calculated data anddown-hole ventilation.The laying route is then designed according to the actual geotechnicalconditions down-hole and the course of the roadway,following the principle of minimizingchanges to the working surface.In this design,the down-hole of the object of the design adopts the extraction method ofthe long borehole with the top plate direction and the extraction method of the high boreholeaccording to the daily and abnormal conditions,which can meet the extraction volume andreduce the cost.Key words:Coal mine;gas emission;gas drainage
