石泉矿井下移动抽采系统研究

本科论文AbstractIn recent years,with the increase of coal mining depth,gas accidents have occurredfrequently in various mines in China,posing more and more serious threats to safety inproduction and restricting the sustainable development of China's coal mines.Therefore,reasonable and effective gas extraction methods are particularly important forChina's high-gas mines.Published according to the state administration of whole productionregulation of coal mine gas extraction from basic indicators (AQ)1026-2006,"standard ofcoal mine gas extraction"(AQ)1027-2006 and "coal mine safety regulations"regulation oftechnical indicators,extraction and safety requirements,combining Shi Quan coal minegeological conditions,climate factors such as gas extraction method,calculation of gasemission,extraction pipeline resistance,and then select extraction pump,form a complete gasextraction system.Mine gas has always been one of the natural factors that threaten underground safety.Preventing gas disaster is of great significance to mine construction and coal production.As akind of clean energy,gas can be exploited rationally and bring considerable economic benefitsto coal mines.In addition,gas drainage plays an important role in preventing gas explosionand coal and gas outburst.This design can provide basis for mine gas control and has certainpractical significance.Key words:Gas extraction:Gas emission:Gas extraction system:Clean energy
