Application of Reverse Reaming in Drilling through the Tunnel
-
Abstract
In the crisis mine deep exploration drilling, abandoned tunnels are inevitable encountered, which bring many difficulties for the normal construction.In this case, the use of reverse reaming technology and casing in the tunnel will re-ceive good effect.The reverse reaming tools are designed to solve the sealing of circulation medium under high pump pres-sure;the geological designing purpose is realized with rapid and economic one-time crossing tunnel.-
