What is a Mining and Subsidence Search?

Whether you're a homeowner, a prospective buyer, or a property developer, understanding the risks associated with mining and subsidence is crucial. But what is a mining and subsidence search? and why should you care?

Key Takeaways

• Mining and subsidence searches assess the risks of ground instability and subsidence caused by historical mining activities, providing information about past mining operations, hazards, and insurance considerations.
• Mining and subsidence can lead to structural damage, sinking ground, and collapse, particularly in areas with a history of mining activities like coal mining or brine extraction.
• The consequences of mining and subsidence can affect property integrity, market value, and insurability, making it crucial to understand and address these risks.
• Lenders and insurers often require mining and subsidence searches to protect their interests, and search results can influence decision-making, insurance coverage, property valuations, and risk mitigation strategies.

What is a Mining and Subsidence Search?

A mining and subsidence search is an investigation conducted during conveyancing to assess the risk of ground instability and subsidence caused by historical mining activities. It provides information about past mining operations, potential hazards, and insurance considerations for properties located in mining-affected areas.

Mining and subsidence can pose significant risks to properties, leading to structural damage, sinking ground, and even collapse. These risks are particularly prevalent in areas with a history of mining activities. Coal mining, for example, can create underground voids that can cause ground movements and subsidence over time. Similarly, brine extraction can result in the dissolution of salt deposits, leading to sinkholes and ground instability.

The consequences of mining and subsidence can be severe, impacting not only the structural integrity of your property but also its market value and insurability. Therefore, it is essential to understand these risks and take necessary precautions to protect your investment.

Furthermore, lenders and insurers often require a mining and subsidence search during conveyancing before approving mortgages or providing coverage. They want to ensure that the property is not at a high risk of subsidence, protecting their own interests as well. Therefore, by conducting a thorough search, you not only safeguard your investment but also fulfill the requirements of stakeholders involved in the transaction.

Subsidence caused by mining is different to minor subsidence which is a less severe form of subsidence that may not pose an immediate threat to the structural integrity of a property. 

What information does a mining and subsidence search provide?

A mining and subsidence search provides valuable information that can influence your decision-making process. It typically includes details such as:

• Historical mining activities: This section outlines the type of mining that took place in the area, including coal mining, metal mining, or brine extraction. It provides an overview of the scale and duration of mining operations, giving you an idea of the potential risks involved.
• Known mining hazards: This part highlights any identified hazards associated with mining activities. It may include information on subsidence events, ground instability, or the presence of abandoned mine workings. Understanding these hazards helps you assess the level of risk and take appropriate actions to mitigate them.
• Monitoring data: In some cases, continuous monitoring of ground movements is carried out in mining areas. This data can provide insights into the current stability of the ground and help assess the potential for future subsidence. It allows you to understand the dynamic nature of the land and make informed decisions accordingly.
• Risk assessments: Based on the available information, a mining and subsidence search may provide a professional risk assessment. This assessment considers factors such as the proximity of mining activities to the property, the geological conditions, and the history of subsidence events. It offers an expert opinion on the level of risk and can guide your decision-making process.

Types of mining and subsidence searches available

When it comes to mining and subsidence searches, various options are available depending on your specific needs and the location of the property. Some common types of searches include:

• Coal mining searches: These searches focus on areas with a history of coal mining. They provide information about past mining activities, potential hazards, and any recorded instances of subsidence. Coal mining searches are particularly important in regions with a significant coal mining heritage.
• Non-coal mining searches: Non-coal mining searches are relevant in areas where other types of mining, such as metal mining or brine extraction, have taken place. These searches reveal details about the history of non-coal mining activities and any associated risks.
• Ground stability reports: Ground stability reports assess the overall stability of the ground, taking into account factors such as mining activities, geological conditions, and historical subsidence events. These reports provide a comprehensive understanding of the risks and help you make informed decisions.
• Historical mining records: Historical mining records provide a wealth of information about past mining operations, including maps, plans, and documents. They offer valuable insights into the history of the land and its surrounding areas, allowing you to understand the context and potential risks.

How to request a mining and subsidence search

Requesting a mining and subsidence search is a straightforward process that can be initiated by your solicitor or conveyancer. They will typically engage the services of a specialist search provider who will conduct the search on your behalf. The search provider will gather the necessary information from various sources, including historical records, geological surveys, and monitoring data.

It's important to note that the availability and extent of mining and subsidence searches may vary depending on the region and the specific search provider. Therefore, it's advisable to consult with your solicitor or conveyancer to determine the most appropriate search for your needs.

Factors to consider when interpreting search results

Interpreting mining and subsidence search results requires careful consideration of various factors. Here are a few key points to keep in mind:

• Risk levels: The search results may provide an assessment of the risk level associated with mining and subsidence. It's crucial to understand the implications of these risk levels and how they may affect your property. Higher risk levels may require additional measures to mitigate the risks effectively.
• Location: The proximity of mining activities to the property is a significant factor in assessing the level of risk. Properties closer to active or historical mining sites may face higher risks of subsidence. Understanding the location and scale of mining operations in the area will help you evaluate the potential impact on your property.
• Professional advice: Interpreting search results can be complex, especially if you are not familiar with mining and subsidence issues. It's advisable to seek professional advice from a qualified surveyor or engineer who specialises in mining and subsidence. They can help you understand the implications of the search results and guide you in making informed decisions.

Mitigating risks associated with mining and subsidence

While mining and subsidence risks cannot be eliminated entirely, there are measures you can take to mitigate their impact. Here are a few strategies to consider:

• Insurance: Obtaining appropriate insurance coverage is crucial to protect your property against potential subsidence risks. Ensure that your insurance policy covers mining and subsidence-related damages and consult with your insurance provider to understand the extent of coverage.
• Monitoring: Regular monitoring of ground movements can provide early warnings of potential subsidence. Consider installing monitoring equipment or engaging the services of a monitoring company to track any changes in the ground over time. This proactive approach can help you identify issues early and take necessary actions.
• Structural assessments: Engage a qualified structural engineer to assess the stability of your property and identify any existing vulnerabilities. They can recommend structural improvements or remedial works that can enhance the resilience of your property against subsidence risks.
• Maintenance and repairs: Regular maintenance and prompt repairs of any defects or damages to your property can help prevent further deterioration and minimise the risk of subsidence. Keep an eye out for signs of subsidence, such as cracks in walls or uneven floors, and address them promptly.
