Tunnels and underground excavations Tunneling techniques
Tunnels and underground excavations Tunnels and underground excavations Tunneling techniques: Tunnels are generally grouped in four broad categories, depending on the material through which they pass: soft ground, consisting of soil and very weak rock; hard rock; soft rock, such as shale, chalk, and friable sandstone; and subaqueous While these four broad types of ground conditionThe construction of underground tunnels, shafts, chambers, and passageways are essential yet dangerous activities Working under reduced light conditions, difficult or limited access and egress, with the potential for exposure to air contaminants and the hazards of fire and explosion, underground construction workers face many dangersUnderground Construction (Tunneling)
