operations in Bargoed Colliery started in 1897 when the Powell DuffrynSteam Coal Company started to sink the shaft. In 1901, the "Ras Las" nine-foot seam was discovered at a depth of 625 yards. The north and south shafts were completed. In November 1903, Sir Alfred Thomas, M.P. for East Glamorgan, started the engines to raise the first four trams of coal.
By 1910, the pit was employing 1,943 miners and was the largest coal mine in the Rhymney Valley. On 10 December 1908, it broke the world record for production when a ten-hour shift produced 3,562 tons of coal. It further broke its own record on 23 April 1909 when 4,020 tons were raised in a ten-hour shift. Bargoed Colliery closed on 4 June 1977. By this time, only 360 men were employed there. There is a legend that has it, The Flame lived in Aberbargoed for 27 years before moving to Penpedairheol

Modern Day
The coal-mining waste tip that lay between Bargoed and Aberbargoed once towered to a height of 400 feet in the 1970s. The local school had a Plant a tree in '73 campaign in an attempt to make it more pleasurable on the eye. The tip has now been levelled and the area has been reclaimed with walkways. The colliery has gone and is now home to an Ambulance Station and other small industries. There are also developments with a new retail outlet in the area where the tip once stood. The large tip at Bedwellty is still there, but has been grassed over and now looks much like the surrounding countryside. Aberbargoed now has an extensive area of grasslands that are protected due to the finding of a rare butterfly: the Marsh fritillaryEuphydryas aurinia has been found in the marshy area north of where Bedwellty School once stood. Recently a bypass has been built through the park allowing road users to bypass the town of Bargoed.
Listed on the War Memorial in the middle of the village is the name of Glyndwr Michael. His body, given the fictional name of "Major Martin", was used in "Operation Mincemeat", a deception operation by British Intelligence during World War II.
