In many residential areas of Cornwall, historic mining activity has created a challenging legacy. Unrecorded mine shafts can pose significant issues for property owners, builders, developers, engineers, and architects—especially during property sales. Often, owners might live near these hidden shafts for years without ever realising their existence.
This blog post explores a recent case study that highlights the need for thorough investigative drilling and the importance of effective communication during such processes.
Understanding the Challenges of Historic Mining
Cornwall has a rich mining history, which, while valuable to the local heritage, brings forth responsibilities for current landowners and developers. Mine shafts that were undetected or unrecorded can lie beneath residential properties, potentially leading to unsafe conditions or property devaluations.
For example, there are estimated to be over 10,000 abandoned mine shafts in the Cornwall region, creating a real risk for unsuspecting owners and builders. The ramifications can be serious, affecting not only property safety but also influencing property transactions.

The Case of the Discovering a Shaft
In a recent case, a property owner was caught off-guard when a potential mine shaft was discovered on their land during the sale process. Like many in Cornwall, they were unaware of the risks historic mining activity presented. With a buyer interested in the property, the owner had little time to resolve the situation.
In such cases, drilling investigations are crucial to determine whether shafts are indeed present. The initial findings led the property owner to engage professionals who could assess the area and conduct necessary drilling investigations.
The Role of the Party Wall Act
As the drilling company prepared to commence further inspections, they identified that the property was close to a neighbouring structure. This proximity meant they needed to comply with the Party Wall Act, which governs what can and cannot be done in relation to shared walls or boundaries between properties.
To navigate this regulatory landscape, a party wall surveyor was essential. Duchy Party Wall Surveying was recommended to manage the situation. Their expertise in handling such delicate matters proved invaluable.
