Dragline/Pre-Strip Integration

Optimize your pre-stripping

This module calculates the results (surfaces, volumes) from a multi-strip Dragline operation. A pre-strip horizon and a spoil profile are calculated for each strip, taking into account the material that must be moved outside the pit by truck/shovel before the dragline operation. Multiple strips of dragline operation are simulated, taking into account Parallel and Perpendicular Ramps included in the calculation. Excavated coal volumes are also calculated and logged block-by-block for each strip.

Quick & accurate long term plan

Spoil dumps
- Other functions allow the rapid design of spoil dumps to accommodate pre-strip material and in conjunction with other modules the life of pit can be modelled incrementally block-by-block and strip-by-strip.
Profiles
- A Strip Line Generator can generate approximate Dragline Strips. Strip lines can also be imported as DXF data. Users mark out the pit boundaries in each strip. They can then rapidly set up profiles for the Low Wall and High Wall geometry in different parts of each pit.
Pit shell
- Parallel and Perpendicular Ramps can be included in the calculation through parameters describing the ramp geometry and the inner surfaces used to construct the ramps.
  
  A pre-strip horizon is first calculated for each strip, taking into account the material that must be moved outside the pit by truck/shovel before the dragline operation. The simulation then calculates the Pit Shell for each strip (i. e. the excavated strip with its Low Wall and High Wall). Excavated coal volumes are also calculated and logged block-by-block for each strip.
