| The workings consist of three adits with 3,300 feet of drifts, raises, and crosscuts. |
|
| Underground mining entails sinking shafts to reach the target resource and driving tunnels and adits, either inclined or horizontally. |
|
| Many adits, shafts and tunnels, some extending over 100 m, pursue these veins deep underground. |
|
| The Jomac mine's three adits lie within the Glen Canyon National Recreation Area boundary. |
|
| Our first target was in the vicinity of the Pinto mine and the Buckhorn mine, where a cluster of adits was indicated. |
|
| The mine's three adits lie in the Shinarump conglomerate member of the Triassic Chinle Formation. |
|
| The orebodies were accessed through several adits and a few shallow shafts. |
|
| Pits that run horizontally into a hill slope or cliff following material into the slope are known as adits or drift mines. |
|
| Very little remains of the old silver mines at Glen Osmond, apart from some of the old shafts, adits and the chimney, the oldest mine building in Australia. |
|
| Eventually stoping cut farther into the veins so that either shafts had to be sunk or adits driven into the hillside to make connections with the underground workings. |
|
| The area has several adits and numerous small pits and cuts. |
|
| Then he's down one of these adits, talking to the tommyknockers, more'n likely. |
|
| Early activity was mainly by levels or adits driven into coal seams from outcrops in the valley sides. |
|
| A trace of metazeunerite was identified in pannings from the dump of the upper of the two adits. |
|
| The use of adits for the extraction of ore is generally called drift mining. |
|
| Most adits are designed to slope slightly upwards from the entrance so that water will flow freely out of the mine. |
|
| Of course, adits are still useful for deeper mines because the water only needs to be raised to the drainage adit rather than to the surface. |
|
| These mines were shallow shafts or adits that exploited the coal seams where they outcropped. |
|
| These adits connected with shafts that were either sunk vertically downwards or followed the line of the steeply dipping lode. |
|
| The secondarily leached silver minerals miargyrite, iodargyrite and bromargyrite, were also encountered in the adits. |
|
|
|
| Area mine workings dating from 1915 include adits, a raise, a winze, trenches and an inclined shaft. |
|
| Thus the area was stabilised by buttressing and inserting drainage adits. |
|
| On the French side at Sangatte, a deep shaft with adits was made. |
|
| Quarrying of limestone, coal and clay took place in Cumbernauld, for example at Glencryan, where adits to the old fireclay mines are still clearly visible. |
|
| Work to date, encompassing six adits and 26 trenches, has outlined a vein system with a strike length of at least 600 metres and a vertical interval of at least 300 metres. |
|
| Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. |
|
| Adits can only be driven into a mine where the local topography permits. |
