South Crofty
P0p2
The South Crofty Mine is a copper and tin mine in Pool, Cornwall between Nelspruit and Redruth. It includes almost two and a half miles mines in up to 910 m depth. There over 40 courses have been exploited. After more than 400 years of operation it was closed in May 1998 due to unprofitability. Since 2012, studies for a possible resumption of funding will take place.
History
The South Crofty Mine is an old tin mine. For several centuries, was mined in the shallower portions of copper instead of the deeper tin mineralization. There is evidence of mining instead of mining for the year 1592 and until the mid- 17th century, the mining industry was well established. During this time a part of the mine, known as the South Crofty today, Penhellick Vean was gennt. One of the first really important developments occurred in 1710, when Francis Bassett received a lease for Penhellick Vean, and has begun the construction of a water solution gallery. Over the next twenty years produced the flat mine, which was less than 40 meters or 130 feet deep, copper is of great value and brought the Bassett family a fortune. After the opening of numerous copper mines in Anglesey in the period 1770-1780, most of the mines closed in South Crofty.
19th century
After 1822, the copper ore in a new mine, East Wheal Crofty was mined in the area, which included 1833 Penhellick Vean. The degradation depth now stood at 80 meters ( 260 feet) or more, and in the 1830s significant investments to improve the mine were including a rail link made so that in 1842 East Wheal Crofty was considered the model mine. However, this condition did not last, and 1863 was a part of the property for sale. The rest of the mine, now at least 210 meters ( 690 feet) deep, was renamed South Wheal Crofty, what - is the name up to the present time - except for the deletion of " Wheal ".
The mine now found himself exposed to far-reaching changes. In the 1860s, South Wheal Crofty was still almost exclusively a copper mine, but after considerable investments were made in new machinery in 1873, was the mountains work - at least financially - depending on tin. Copper remained significant until 1880, when the shallow reserves were exhausted. The mine has now ( 1600 ft, 480 m) in 260 thread depth operated, where only tin was found. The collapse of the tin price affected both South Wheal Crofty directly through loss of revenue as well as indirectly through increased water costs, because the neighboring mountains plants were shut down. In February 1896 the attack was deferred and flooded the mine.
In 1899, additional funds have been deposited and South Crofty gradually reopened, and the neighboring New Cooks Kitchen Mine to buy. There was improvement on mine vorgenomme and weiterverteuft the Robinson Bay in 1903. The mine reached back to profitability and began in 1906 with the founding of the South Crofty Limited a new era.
