Assessment of the Prospective Water Inflow Hazards Using Georadar: Case Study of Upper Kama Potash Deposit

摘要

The problem of prevention of the water influx in the potash mines is vital for proper planning of the safe ore extraction and timely collapse hazard mitigation action. Geophysical methods provide with the effective tools for studying the fractures, which are the possible water passageways into the mine. Previous works showed that usage of georadar might be a valuable solution for fracturing investigation in salt rock. The investigations were conducted in the Solikamsk Mine #3 (former JSC Silvinit), where the wide fracture zone was encountered during ore extraction. This study allowed delineation of single fractures and their systems including the hidden features inside the surrounding rock mass.
