Conventional & Machine Mine Tunneling Capabilities

Capitol Tunneling offers extensive experience in both conventional and machine mined tunneling. Conventional tunneling, also known as hand mine tunneling, is commonly used to tunnel through soil, rock and fill. Tunnel installations using the hand mining methods are ideal for shorter, smaller diameter tunnels that don’t justify the expense of mobilizing a larger scale Tunnel Boring Machine to perform the work. Often, we still utilize specialized hydraulic tunneling shields to provide shoring and safety to both the traveling public as well as the hard working Capitol Tunneling employees diligently working to drive the tunnel. Since its inception, Capitol Tunneling crews have installed more than 125,000 feet of hand-mine tunnel, ranging from 4 feet to 18 feet in diameter.

Capitol Tunneling also provides the single-pass and two-pass methods of machine mine tunneling. Machine mining utilizes a Tunnel Boring Machine (TBM) to mechanically excavate the face of the tunnel. TBM’s are typically used on larger diameter, longer runs where the expense of these monstrous machines can be absorbed over a larger quantity of tunnel excavation Utilizing equipment we have acquired over the years, as well as several longstanding relationships with various machine manufacturers, Capitol Tunneling is able to custom fit a machine to nearly any application. We have the expertise and know how to trenchlessly navigate your tunnel from start to finish, on line…on grade…and on time.
