Tunnels and underground excavations, horizontal underground passageway produced by excavation or occasionally by nature's action in dissolving a soluble rock, such as limestone.A vertical opening is usually called a shaft.Tunnels have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting water and sewage.
Underwater Antraquip hydraulic cutters are designed to operate under water without requiring any modifications making them ideal for rock dredging projects. The cutter head allows for the operator to grind the rock underwater continuously and offers excellent results compared to other options traditionally used (breakers).

Dexpan Non-Explosive Demolition Agent is a powder with amazing 18,000 PSI expansive strength when mixed with common water. Poured into the same holes where explosives are traditionally placed in, Dexpan® breaks reinforced concrete and rock safely, while providing SILENT cracking.
Hydro excavation lessens the risk of damaging utilities, which may often be inaccurately mapped and located and marked on the surface. A suction excavator is useful in bulk excavation in confined areas, where its suction hose can reach in over or through barriers, e.g. digging a swimming pool in a courtyard.
Underwater drilling and blasting can sufficiently fragment the rock to allow for it to be dredged. Underwater blasting or submarine blasting as it is otherwise known is done for a range of projects.
Proponents of the view that the sites are man-made point out features such as two round holes (about two feet wide) and a straight row of smaller holes that appear to have been an attempt to split off a section of the rock by means of wedges, as in ancient quarries.
