Track 4: Coal

207 Finally, the proposed method has already been implemented at the Rudna mine, where it supported a design choice that balances operational safety with production efficiency. This demonstrates the applicability of the workflow as a practical decision-support tool for deep room-and-pillar operations, particularly when combined with systematic underground monitoring and continuous model updating.
