Settlements that are made near a mining area are often confronted by a number of challenges. Living close to a mine could affect the quality of life and the health of the homeowners. The noise, vibration and dust could only heighten the problem. The environmental assessment process has to be taken into consideration before starting a building construction. The assistance of reputed architects with proven expertise in mine land construction like Besten, Stantec, etc. could provide the right guidance in this context. If your settlement is nearby a gold mining, read the guidelines at http://www.gold.org/. The information can help in going forward in the right direction.
Stories of houses constructed on mines sinking are not just stuff seen in nightmares. There are thousands of disused mines across the nation and more and more residential settlements are built here. The news of homes sinking is a phenomena that needs to be discussed in detail, before it starts to dominate the news. Why this happening and what is are the remedies will be discussed in the article going further.
Types of mine settlements
There are two types of mine settlements, Creep settlement and Collapse settlement. The former is a routine settlement on loose earth materials accumulated over a period of time.. The latter is technically called Hydroconsolidation due to the association with rising groundwater. In this type, the rate of settlement depends on factors like compaction, moisture, groundwater conditions and the fill’s depth.
Cracks on the walls are the first sign to look for. This could just be a sign of another problem, so do not conclude that your property is sinking. Professional advice from best structural engineers or surveyors, from reputed institutions and associations, could be the right approach. They will help to find out what is causing the structural issue and can advise on solutions to keep your home stable. Inform your insurance and mortgage lender immediately.
Checking your home for risk
Continued inspection from the mining authorities deeming the place safe and needs no further attention is an indication that your home is safe. If there are any issues, the authorities will contact you, and if they haven’t then there is nothing to fear. For those buying property in the mine area it is recommended to get the Mine Search Report or Archival Mining Report. This can indicate if there are mining underneath your property and take immediate action. If there is a mining going underneath your property, call upon a specialist company to investigate the ground conditions. Get the full structural mining report.
There is evidence that extensive damages have occurred in home built after carefully engineered valley fill. There are cases where the rising groundwater in the fill causes plumbing leaks and concentrations of rainwater. These will not come as a surprise for engineers as they are familiar that large rocks carefully engineered are compacted to hold back water in large volumes. For hydro consolidation few rules hold good, like compaction and in less than 20 feet depth there is no risk.
Understanding the guidelines and following the rules can help in providing sustainable homes that last for generations.
