Engine Vein

Overview

A 75-foot-deep open scar in the sandstone at Engine Vein marks four millennia of mining -- from Bronze Age stone hammers to a Roman coin hoard hidden in a shaft, and finally a 20th-century capping built to keep out reckless explorers.

History

Engine Vein is perhaps the oldest mined site at Alderley Edge, with finds of Bronze Age stone hammers recovered from its workings; Roman coins found in a shaft now known as Pot Shaft, confirmed by archaeological excavation, showed the shaft itself had been dug in the 1st century AD. The workings visible today, though, most likely date from the activities of Charles Roe between 1755 and 1771, and from a company of Stockport men working between 1804 and 1810; the mineralised sandstone on the vein's southern side was then extensively mined by the Alderley Edge Mining Company between 1860 and 1877, with possible further reworking by other operators in 1911 and 1919. Unlike the more dispersed workings of West and Wood Mines, Engine Vein's earlier mining followed the fault itself directly rather than scattered ore pockets; the Alderley Edge Mining Company later connected the mine to its wider works via two ore chutes and the mile-long Hough Level tunnel. The open-cast working of the Engine Vein fault left a large, deep scar -- some 75 feet at its deepest point -- that, like the complex's other mines, drew in unauthorised 20th-century explorers and, with them, the accidents that followed. The opencast was capped in 1981 at a depth of about 25 feet specifically to prevent inexperienced visitors from gaining entry to the mine that way; a proper entrance was instead made into the mine at the side of the opencast, with access now strictly controlled. The mine today is reached via an adit dug open by the Derbyshire Caving Club in that same year, 1981. Underground, walking passage leads from the entrance to a main passage that includes a chamber once open to the air, now capped with a concrete slab, where the vein itself is visible in the roof; a steep descent leads to an ore chute connecting to the Hough Level. The mine also gives access to Bear Pit and the inclined Blue Shaft, both leading down to the Hough Level, and to small coffin levels and a run-in from the surface near its far end. Most of Engine Vein was worked either directly along the fault -- spanning the Bronze Age to the 18th century -- or to the south of the fault, in 19th-century workings.

Geology

A copper-bearing fault vein at Alderley Edge, worked along the fault line itself in earlier periods and across a wider area to its south in the 19th century.

Workings

A large open-cast scar (75 feet deep, now capped), a coffin-level adit, Pot Shaft (Roman), Bear Pit, the inclined Blue Shaft, and ore chutes connecting to the Hough Level.

Closure

Extensively mined by the Alderley Edge Mining Company from 1860 to 1877; possibly reworked by other operators in 1911 and 1919.

What remains

Owned by the National Trust; the 1981-capped opencast and a Derbyshire Caving Club adit control access, with guided visits available by prior arrangement.

A large capped open-cast scar, a secured adit entrance, underground chambers with visible vein exposures, Bear Pit, Blue Shaft and ore chutes connecting to the Hough Level survive.

Recorded claims

Individual factual claims, each attached to the source(s) that support it below. Where sources disagree, both are kept.

• Engine Vein Mine is perhaps one of the oldest sites of mining at Alderley Edge with finds of stone hammers dating it to the Bronze Age; Roman coins found in a shaft, now called Pot Shaft, and archaeological excavation of that shaft established it to be Roman, dug in the first century AD. ¹
• The large deep scar (75 feet at its deepest) left by the open-casting of the Engine Vein fault attracted some foolhardy explorers in the 20th century, and the opencast was capped in 1981 at a depth of about 25 feet to prevent inexperienced adventurers gaining entry to the mine by this route, with an entrance instead made into the mine at the side of the opencast. ¹
• Engine Vein is a 750 metres long, 60 metres deep vertical vein mine; coffin levels strongly suggest working in the 18th century, the western extremity was probably worked by Ashton in the early 19th century, and a substantial volume of ore was also removed in the middle or late 19th century, so the mine was probably worked over four millennia. ²
