Seamless Transition from Stope Optimization to Drilling

The process of drilling after stope optimization is a crucial stage in underground mine planning, enabling the seamless integration of optimization results into detailed drilling designs. In this video, we demonstrate how K-MINE tools streamline this process by first performing stope optimization using the Stope Optimizer module, followed by designing a drilling pattern for a selected area with the Design Fan of Blastholes feature. This approach ensures maximum accuracy and efficiency throughout every stage of deposit development.

The journey begins with stope optimization. The Stope Optimizer tool analyzes the block model, considering critical parameters such as ore grade, stope geometry, minimum and maximum stope dimensions, and economic constraints. After configuring parameters like minimum stope height, permissible slope angles, and grade thresholds, the software performs precise calculations. The result is an optimal stope layout, visually identifying economically viable mining zones that meet technical and economic requirements. In our example, we select one of the optimized clusters for subsequent drill and blast design.

The next step is designing drill fans for the selected cluster. With the Design Fan of Blastholes tool, users can configure drilling parameters, including hole diameter, depth, fan angles, hole spacing, and drilling direction. This tool provides flexible dynamic design capabilities, allowing users to adapt the drilling pattern to the stope’s unique geometric characteristics. With built-in automation, the program completes the detailed design in seconds after basic parameters are specified.

After designing the drilling pattern, it undergoes analysis. The resulting data are visualized in 3D, providing a clear view of how effectively the drill fans cover the selected cluster. Additionally, the system calculates key metrics such as total drilled length, the volume of extracted ore and waste, and the estimated amount of drilling material required. These metrics are crucial for preparing production plans, evaluating costs, and monitoring drilling operations.

The design results can be exported in convenient formats for use with drilling equipment, ensuring precise execution on-site and minimizing the need for adjustments. All project data are saved, allowing users to revisit and update them as needed for further analysis or recalculations.

In conclusion, this video demonstrated how K-MINE integrates stope optimization and drill and blast design into a unified technological workflow. This approach enhances planning accuracy and significantly reduces time and material costs across all stages of deposit development.
