adits's Usage Examples:

With the exception of the Red Marls forming the upper part of the Keuper, most of the New Red Sandstone is permeable, and some parts contain, when saturated, even more water than solid chalk; but, just as in the case of the chalk, a well or borehole in the sandstone yields very little water unless it strikes a fissure; hence, in New Red Sandstone, also, it is a common thing to form underground chambers or adits in search of additional fissures, and sometimes to sink many vertical boreholes with the same object in view.

In practice it is usual in chalk formations to imitate artificially the action of such underground watercourses, by driving from the well small tunnels, or " adits " as they are called, below the water-level, to intercept fissures and water-bearing beds, and thus to extend the collecting area.

In mines that are worked from the outcrop by adits or day levels traction by locomotives driven by steam, compressed air or electricity is used to some extent.

Cars may thus be run through long adits or through branch gangways to some central point for making up into trains.

As already noted large pillars must always be left to protect shafts, adits and the more important mine-passages necessary for drainage, ventilation and the haulage of mineral.

i and 2 illustrate the development of a metal-vein by two adits, two inclined shafts in the lode, and by a deep vertical shaft connected with the lode by horizontal cross cuts.

Large pillars of mineral should be left for the protection of the main openings, whether these be shafts or adits.

At the same time provision must be made for the integration of knowledge as well as for the winning of it by several adits.

And it is not only the perceptions of eye or ear which tell, but also the association of concepts behind these adits of the mind.

The mines are, in general, situated on the slopes of the hills and are easily opened up by adits.

adits's Meaning':

a nearly horizontal passage from the surface into a mine
