Mine Subsidence represents a critical challenge in underground mining, manifesting during or post-mining operations, with the potential to damage nearby structures and residences. The Company’s strategy is the implementation of proactive prevention and mitigation plans. These plans are developed based on thorough mine subsidence risk assessments and surface impact analysis. The Point Hatteras Extraction Plan is a blueprint designed to guide the mining operations with support by sophisticated modeling techniques that simulate the potential impacts. Furthermore, the Company has established a network of monitoring stations focused on tracking the width of surface cracks to prevent and halt subsidence before exceeding the maximum allowance limits.
