系指在凿井的同时掘进附近的巷道。井筒附近巷道按用途分以下几种:井筒马头门和井底车场;井筒之间的联络道;箕斗装载仓;排水设备峒室和其它巷道。井筒附近巷道掘进速度低(200～240立方米/月)的原因是,在这些巷道内不能使用高效率设备,因为所用装岩机和凿岩机的 It refers to tunneling near the tunnel while sinking. Roadway near the wellbore is divided into the following categories according to the purpose: the wellhead Ma Taumen and the bottom-end yard; the contact road between the wellbores; the skip loading bin; the drainage equipment and other tunnels. The reason for the low tunneling speed (200-240m3 / month) near the wellbore is that high efficiency equipment can not be used in these tunnels because of the use of rock loader and rock drill
