How It Fits Into Your Workflow<\/strong>\u00a0<\/h2>\n\n\n\n

When activated, the Interhole Distances dialog overlays the drill pattern with a network of lines, instantly revealing the \u201chealth\u201d of the pattern and any deviation from blasting specifications. Whether reviewing a new design, verifying as-drilled patterns, or auditing for quality assurance, this tool gives engineers the transparency to make informed decisions with confidence. <\/p>\n\n\n\n

For example, a plan view can be generated showing color-coded distances at the collar elevation, pinpointing a cluster of boreholes deviating from the design. The engineer can either adjust planned explosives loading or instruct the drill crew for redrilling as necessary\u2014saving cost, enhancing safety, and boosting blast outcomes. <\/p>\n\n\n\n

Understanding Interhole and Row Distances<\/strong>\u00a0<\/h2>\n\n\n\n

At its core, this tool measures the spacing between: <\/p>\n\n\n\n

    \n
  • Individual boreholes<\/strong> (Mode \u201cBorehole distances\u201d)\u00a0<\/li>\n<\/ul>\n\n\n\n
      \n
    • Entire rows<\/strong> of boreholes (Mode \u201cRow distances\u201d)\u00a0<\/li>\n<\/ul>\n\n\n\n

      These measurements are calculated using a projection plane <\/strong>\u2013 a virtual slicing layer that defines the height at which the distances are evaluated. Whether you need to inspect spacing at the collar, mid-bench, or near the toe, the projection plane offers the flexibility to do so.<\/p>\n\n\n\n

      Customizable Projection Plane: Precision in 2D Layers<\/strong>\u00a0<\/h2>\n\n\n\n

      The projection plane isn\u2019t just a static reference, it\u2019s adjustable to reflect real-world bench geometry. You can: <\/p>\n\n\n\n

        \n
      • Switch between Horizontal<\/strong> and Parallel to Floor Plane<\/strong> modes using the radio buttons.\u00a0<\/li>\n<\/ul>\n\n\n\n
          \n
        • Enter a specific height in the Plane height<\/strong> field for precise elevation control.\u00a0<\/li>\n<\/ul>\n\n\n\n
            \n
          • Use Move to Toe<\/strong> to instantly align the plane with the borehole toe elevation.\u00a0<\/li>\n<\/ul>\n\n\n\n
              \n
            • Use Move to Collar<\/strong> to align it with the borehole collar elevation.\u00a0<\/li>\n<\/ul>\n\n\n\n
                \n
              • Activate Show plane in 3D view<\/strong> to visualize the plane directly in the model.\u00a0<\/li>\n<\/ul>\n\n\n\n
                  \n
                • In Edit mode<\/strong>, drag the arrow handle in the 3D viewer to reposition the plane interactively.\u00a0<\/li>\n<\/ul>\n\n\n\n

                  This flexibility allows engineers to inspect spacing at multiple levels, ensuring any alignment issues are caught whether they occur near the surface or deep in the bench. <\/p>\n\n\n\n

                  Color-Coded Feedback: Instantly Spot Deviations<\/strong>\u00a0<\/h2>\n\n\n\n

                  Once tolerances are defined, BlastPlanner uses color-coded annotations<\/strong> to signal whether a spacing falls within spec: <\/p>\n\n\n\n

                    \n
                  • Green<\/strong> = Distance is within tolerance\u00a0<\/li>\n<\/ul>\n\n\n\n
                      \n
                    • Red<\/strong> = Distance falls below defined limits\u00a0<\/li>\n<\/ul>\n\n\n\n

                        This analysis works for both borehole distances<\/strong> and row distances.<\/strong> <\/p>\n\n\n\n

                        In addition, row distance mode can display a heat map<\/strong> where color intensity corresponds to the magnitude of deviation, making it easy to detect systematic spacing issues across the blast site. <\/p>\n\n\n\n

                              The Payoff: Pattern Confidence Before the Blast<\/strong>\u00a0<\/h2>\n\n\n\n

                              What sets BlastPlanner\u2019s Interhole Distance analysis apart is not just its accuracy, but its usability. With a clean visual interface, live feedback, and exportable data, it brings transparency to an area of blast design that often goes unchecked. <\/p>\n\n\n\n

                              This feature helps engineers: <\/p>\n\n\n\n
