A Case Study- Investigating Ground subsidence due to Secret Mining and Repairing Damaged Structures
An interesting study is reported on establishing secret mining activity resulting in severe ground subsidence which occurred and was corrected later in a village called Dhery Saydan located near the world famous salt range region of Pakistan and is located on a hill top with about 2000 inhabitants. After reviewing many cases of similar nature and on basis of geophysical techniques like resistivity survey, it was established that secret mining activity had taken place resulting in massive cracking of dwellings coupled with sinking of water table. Thereafter a suitable construction methodology was applied to correct the huge structural defects and make the dwellings functional.
