History

The Clifton and Kearsley Company's coal reserves were becoming depleted in the Irwell Valley

 at a time when demand for coal was high and in 1907 its subsidiary company sank a 24 inches (61 cm) bore hole at Astley Green, north of the Bridgewater Canal to investigate untapped reserves of the concealed coalfield. The company acquired the mineral rights for 700 acres (283.3 ha) of land under Chat Moss which stretched beyond the Liverpool and Manchester Railway

No 1 pit was sunk to 890 yards primarily to win coal from the Trencherbone mine and No 2 pit was 833 yards deep. The shaft was 23 feet in diameter. The Crombouke and Rams mines were intersected by the sinkings. Firedamp

 to the canal east of Astley Green. It was out of use by 1913, when the sidings and tipping plant were sold to the Clifton and Kersley Coal Company to be used by the new colliery.

In 1923 the colliery employed 1524 men underground and 436 surface workers; that number had increased to 1631 underground and 492 surface workers by 1933. At Nationalisation in 1947 the colliery employed 1375 below and 561 above ground. The surface workers included women, known as pit brow lasses, who sorted coal on the screens. Women were employed at Astley Green until the mid-1950s.
