摘　　要：为保证W3305工作面正常回采,需及时对W3305工作面胶带顺槽、进风顺槽内的瓦斯进行抽采管,根据现场情况,设计了W3305-2胶带、进风顺槽各敷设一趟Φ355瓦斯管,用于该工作面煤层预抽;W3305高抽巷敷设两趟Φ710管路,用于高抽巷抽采;预抽管路与北翼回风西大巷Φ820瓦斯干管相连,由鲍村瓦斯泵站进行抽采的方案。确保了工作面的安全有序生产。In order to ensure the normal mining of W3305 working face,it is necessary to timely extract gas from the tape and air inlet grooves of W3305 working face.Based on the on-site situation,Φ355 gas pipe has been designed to be laid in W3305-2 tape and air inlet grooves for pre extraction of coal seams in this working face.LayΦ710 pipeline twice in W3305 high extraction roadway for high extraction roadway extraction.Pre-extraction pipeline is connected toΦ820 gas main pipe in north wing return air west main roadway and the gas pumping station in Baocun is used for pumping,which ensures safe and orderly production of the working face.
