A process has been developed for reinforcing the walls of ground tunnels which, on analogy with the ''in-the-ground'' method, is called ''pipe-in-the-ground'' method. The process consists of three operations: drilling a hole, filling the hole with th

Cutting curved boreholes with pneumatic punches

Autor: K. S. Gurkov, G. A. Tkachenko

Publikováno v: Soviet mining science. 17:184-187

Further improvements to these devices have made it important to study the interaction of the pneumatic punch with the soil as it moves in a curved trajectory. To cause such motion, there must be enough friction between the casing of the pneumatic pun
