. After the disaster of 1853, it was redeveloped as the New Primrose Colliery, owned by Sir Ralph Howard, and by 1896 employed 307. It closed in the early 1900s, but from 1908 was revived as a pumping station for the Tarenni Colliery.

Tirbach Slants

The major coal seams are located close beneath the valley floor, but mean accessing steeply declining seams which run in high geological fault structures, running directly under the River Tawe. This makes the coal easily accessible, but also dangerous to extract.

The first drift mine workings occurred in the late 1800s, at a site referred to at the time as the Tirbach Slants. The Pwllbach Colliery Company started development in 1898 of two slants, main and reverse, and after a series of lease changes which reverted the lease to the Pwllbach Colliery Company, production started in 1905. After the company collapsed into administration in 1924, the lease was taken over by the Pwllbach, Tirbach & Brynamman Anthracite Collieries Ltd, which in 1938 became Henderson's Welsh Anthracite Collieries Ltd.

These companies all worked the same seams: Big (abandoned 1939); Peacock (or Brass); Middle and Lower seams. The workings employed 651 in 1936, the height of its production. The site was closed from February 1940 due to geological difficulties, with 500 men given notice in January 1940. At this time during World War II

, labour was expensive, so it is likely that economics also played a large part in the decision to close. The mine reopened in May of that year, but had been completely abandoned by December 1940.

The site then became a disposal centre for extract from the main Tarenni Colliery, and after nationalisation, the National Coal Board

Tarenni Colliery

Opened in 1903 by the South Wales Primrose Coal Co Ltd, pit No.1 called Tarenni (143 yard) was sunk to work the Red vein under Ynys Wil Hernyn Farm. A sister pit further north, Gleision (Tarenni No.2, 443 yard), was sunk deeper to work the Big and Peacock veins, but faults made it difficult to work. There was a steep cross measure drift developed to connect the two shafts. Coal was distributed through access to either the Great Western Railway

By 1908, Tarenni employed 427 men producing anthracite, which had grown to 803 by 1918, and 947 by 1923. By 1933, the mine was producing 140,000tonnnes per annum of anthracite. From 1937, the company started development workings to check the Big vein south, sinking the No.1 shaft to 576 yard. But development work stopped due to World War 2, and by 1938, there were a total of 522 men working the complex, with over two thirds deployed on No.1 shaft.

The Red vein workings in No.1 were abandoned in 1941, with a further reduction of 100 men achieved by reducing workings on the Big vein to one shift. The developent work on No.1 shaft continued after the war, approved for an investment of £150,157 by the Ministry of Fuel and Power to access the Lower Peacock seam in a more stable area. Further investment was made by the purchase and refurbishment of a new 0-4-0WT shunting locomotive, formerly of the Great North of Scotland Railway

Disaster history

On 13 October 1858, when the Primrose Colliery was owned by Morgan and Lewis, fumes of an engine boiler suffocated 14 men and boys, and 7 horses.

According to HM Inspectorate of Mines and Quarries data, outside the Gwendraeth valley, Tarenni Colliery had the highest set of recorded incidents for coal damp and methane gas explosions. In total during its production lifetime, there were six outbursts in which three men lost their lives: one on 12 December 1914; two on 17 February 1941.

On 1 November 1909, water from the abandoned Ynysgeinon pit caused the death of five miners at Tarenni No.2.
