The Mining Remediation Authority has confirmed that a sinkhole which swallowed a road sweeper in Porth, Rhondda Cynon Taf, last month was caused by historical coal mining. The collapse occurred on February 2 in a lane near the old bus depot, prompting the evacuation of five homes on Aberhondda Road as a precaution.
No injuries were reported in the incident, which saw the council vehicle fall into the void. The road was temporarily closed by South Wales Police while the authority conducted initial investigations and stabilised the area with stone, allowing residents to return home shortly after.
In a statement, the Mining Remediation Authority said: 'Following the significant ground collapse in Aberrhondda, Wales, we have now completed our ground investigations. These have confirmed that the incident is related to historical coal mining.' The authority added that it will 'continue to monitor conditions while we develop and assess options for a permanent repair.'
A witness who arrived at the scene described the situation as 'extremely dangerous,' noting that the ground beneath the sweeper was 'completely gone.' Rhondda Cynon Taf Council confirmed that the driver was safe and well, and that the authority was supporting the investigation.
The Mining Remediation Authority urged anyone suspecting a coal mining hazard to contact them on 0800 288 4242, a 24-hour helpline. The organisation emphasised that 'keeping people safe and protecting the environment remains our priority.'
