From pit survey to blast plan

Crosscut is software for mine surveyors, geologists and blasters. Build block models and surfaces, design holes and blasts, exchange drawings with AutoCAD.

Video: Pexels. The wireframe is computed from this video; the blast parameters are illustrative.

Features

About 134 commands are grouped into six sections. Each section is a separate plug-in, so the ribbon keeps only what you use.

Block models

18 commands

A model is built from an outline or from samples. Cells are coloured by grade, and reserves are calculated by level and domain.

  • Merging cells, assigning values by region, formula calculator, cell table
  • Tonnage: total, by level, by domain
  • Cut-off grade–tonnage curve and raising the cut-off
  • Section by a plane, cell information, model check
  • Import and export, sample import

Drillholes and rocks

3 commands

Drillholes are shown as tubes coloured by interval. The interval table is edited right in the program.

  • Import drillholes from a CSV table
  • Editing intervals in a table
  • Rock reference with their properties

Blast design

22 commands

From the hole grid to the blast plan. Charging rules, delay pattern, powder factor and safe distances.

  • Block, grid, adding, copying and renumbering holes
  • Charging rules and hole charge, explosives and initiation device reference
  • Delay pattern: row-by-row, diagonal, V-cut
  • Volume, powder factor, fragmentation and flyrock zone calculation
  • Blast plan, hole sheet, charging sheet, blast log
  • Section along a row and import of as-drilled data from the rig

Wireframes and surfaces

23 commands

Wireframes are built from points and lines, checked and repaired. Contours and sections are then taken from them.

  • Surface from points, pipe along a line, outline extrusion
  • Union, subtraction and intersection of wireframes
  • Auto-repair, edge stitching, normals, hole filling, self-intersection search
  • Simplification, remeshing, smoothing, offset
  • Cut at an elevation, section along a line, contours, mesh report

Point clouds

23 commands

Scans and drone surveys are imported whole. The ground is separated from everything else, then benches are found on it and volumes calculated.

  • Import, thin out, remove noise, clip box
  • Point classes, ground extraction, classification by outline
  • Crests and toes, normals and slope
  • Comparison with a surface and with another cloud, stockpile volume
  • Point-pair alignment and fine alignment, surface from a cloud

Drawing and editing

45 commands

The familiar CAD toolset with mining geometry: graded alignments, points at a step and projection onto a surface.

  • Graded alignment, offset, smoothing, densifying, outline
  • Project a line onto a surface and set an elevation
  • Points by step, by angle and distance, elevation labels
  • Move, copy, rotate, mirror, scale, stretch
  • Trim, extend, smooth curve, quick select

From data to plan

This is how work on a single level goes.

Import

DXF from partners, a point cloud from the survey, drillhole tables.

Model

A block model, wireframes, sections by any plane.

Design

A hole grid, charges by rules, the flyrock zone in the view.

Output

The plan in FastReport and drawings back to DXF.
