The excavated material will be loaded by a shovel dozer on a dump truck and transported to the storage site. At the beginning you have enough time and no major problems. Once the TNT charges are placed you can start the blasting to create the tunnel entrance. Blast rocks, drill tunnels and force your way through every mountain. As soon as the entrance is cleaned up the huge tunnel drilling machine will march up. But this monster can only start operation if it is supplied with sufficient build.
