Despite modernisation efforts, the first decade of the twentieth century saw a sharp decline in the Welsh slate industry. This was caused by a combination of a slump in the
British building industry, competition from foreign slate producers, particularly France, and an increase in the use of roofing

Oakeley quarries were avid users of technology, allowing them to reduce their costs and increase their production. In 1856 they began to light the quarry using piped gas. A large steam-driven cutting mill was opened around 1860. Nathaniel Mathew, the owner of Middle Quarry pioneered the use of

Oakeley continued to send slate over the

Problems caused by the complex but separate workings had arisen as early as the 1860s. The Welsh Slate

By 1840 the slate that could be easily accessed by surface quarrying with contemporary methods was exhausted, so the quarries began underground mining. Complex arrangements were written into the leases to ensure that the underground workings did not conflict. Production at all three quarries
