西坡矿井下移动抽采系统研究

本科论文AbstractIn scientific development,social security in progress,with the development of gas mining industry,mine safety caused the country attaches great importance to,mine safety has a crucial effect on the gas,the gas is one of the important elements of production safety,some recentyears,the mine continued to dig,raises the risk of danger in mining operations,is more important to the effective management of gas,so that gas can better management for mine safety is indispensable,because before mining gas already cannot satisfy production,so the deeper mining depth,hazard is caused by measuring less gas.Optimize gas extraction system;Less gas metering system drainage,gas zone more secure.The gas drainage rate has been improved,andthe safety of gas discharge pipeline with less measurement has been enhanced.In the gas mining engineering,the mechanism of gas extraction on this basis can be analyzed comprehensively.It shows that the best effect is the comprehensive extraction operation,effectively preventing and controlling the harm of mine gas.Key words:mine gas;extraction technology:gas hazard;gas prediction
