Modern mining techniques

We want to be a good neighbour and that means constantly assessing the impact of our activities upon others and diligently implementing mitigation techniques to prevent any problems from developing.

Under the ISO 14001 standard, we have a variety of measures in place to carry out environmental monitoring of noise, dust, vibration and water quality.

We have monitoring points surrounding the perimeter of Ffos-y-fran in addition to those within the local community. All of our monitoring devices are analysed by independent experts to ensure we comply with levels agreed to as part of the planning conditions for the site.


We have a number of noise monitors at key locations within the local community, which continuously record noise levels and sounds, so that we can identify and verify noise sources. Noise levels are strictly controlled and policed by the local council.



We constantly implement measures to minimise the amount of dust that may occasionally emanate from the site under certain conditions. These measures include using 50,000 litre water bowsers and four fog cannons spraying a fine mist of water over the excavations and running surfaces on the site to ensure that rising dust is kept to a minimum.

In addition dust monitors located around the perimeter of Ffos-y-fran and within the local community, measure dust from the site. The dust monitors take the form of sticky pads, which are regularly changed, and measure any dust deposited and the direction it came from. We have permits with both Merthyr Tydfil County Borough Council (MTCBC) and Caerphilly County Borough Council (CCBC) which relate to any dust produced from the loading, haulage and processing of coal. These are regulated and regularly audited by MTCBC and CCBC.

Air Quality

Noise monitoring points

We have various measures in place to ensure high air quality standards. We deploy the latest technology which measures the amount of fine particulates of dust in the air.


We have permanent monitors within the local community which measure vibration from blasting on site. There are also portable monitors set up on site to record each blast to ensure we are complying with the relevant regulations.

Water Quality


To ensure a high water quality, we have probes in all of our lagoons at Ffos-y-fran, which monitor both pH and suspended solids within the water. We also have dedicated members of staff who continuously monitor the water quality leaving the site. All water discharges are licenced for quality and volume limits and are regulated by Natural Resources Wales.
