Introduction

This section gives an overview of the Open Pit system.

Open Cut Design

This section describes the tools available for the creation and modification of open cut mine designs and dump or stockpile designs. The tools are for straight projections only. Mine designs with ramps or haul roads are handled by the Ramps module.

Integrated Stratigraphic Planning

This section describes the tools available to edit open pit triangulations by attribute.

Ramps

This section describes the tools available for the creation and modification of open cut mine designs, dumps or stockpile designs with ramps and haulroads.

Phase Design

This submenu combines some existing Open Pit tools and introduces new ones that allow you to create open pit phases or push back strings in a simple and fast manner. From these pushback strings, you will be able to create solid triangulations, which can then be used to calculate reserves from a block model.

Pit Layout

This section describes the options that allow you to define mining blocks or strips, edit and name them. These blocks can be used for scheduling and further mine design work.

Terrace Mining

This section describes the block reserve options for selective open cut coal mines where the coal seams are steeply dipping, and the mining method involves the creation of horizontal or near-horizontal benches to access the coal.

Benching and Batters

This section describes how to model flat or undulating deposits using 2D surfaces such as grid meshes or triangulations. This module is used primarily in the coal mining sector.

Batvol

This section describes the block reserve options for flat or undulating deposits using 2D surfaces such as grid meshes and triangulations. The module is used in conjunction with the Benching and Batters module.

Dump File Reporting

This section describes the options that allow you create dump file reports.

Pit Volumes

This section describes how to create sectional profiles of two surface triangulations, for example, a topography and a pit design, and then to calculate the contained volume using the end area section method.

Bench Volumes

Use the Bench Volumes option to calculate the cut and fill volumes (volume changes) between two open-cut mine designs on a bench by bench basis and optionally subdividing by polygon in each bench.

Haulage Profile

This section describes the options that allow you to calculate truck haulage routes based on a series of user-defined input parameters.

Section Design

This section describes the options that allow you to perform design work in section, generate profiles of surfaces, and to calculate the end area volumes between surfaces. This module is used extensively in rehabilitation.

Monitoring

This section describes the options that allow you to calculate, view, manipulate and plot samples of data values obtained from monitors. Monitors are devices that record information over time. This includes measurements from total stations survey systems to monitor slope movement in pits and pollution monitoring devices to record varying pollutant levels. Data obtained through monitors is referred to as _time series data_. The Monitoring module is fully integrated with the other Vulcan modules such as the Animation module for 4D visualisation and the Statistics module for statistical analysis of the monitors. The module is used in the geotechnical or environmental area as well as in open cut mining for bench movements.

Dozer2000

This section describes the options under the Dozer2000 submenu, which allow you to transfer/convert Vulcan data, such as design objects and a triangulation or grid file, so that it can be directly imported into Leica Geosystems' Dozer 2000 application.

Dig Limits

This section to apply geostatistical techniques to the block information to measure the profit of the blocks in the dig limit, in comparison to a penalty based on the mining equipment constraints. This module is designed to obtain a quality line for grade control maximising the economic benefit from a blast material classification.

Oilsands Options

This section to apply various block model, dilution, and ring procedures as they apply to Oil Sands.

Automated Pit Designer

This option allows you to create an open pit design or dump. It uses information from given block models to set slope and angle parameters by recognising different zones, or they can be setup by defining them interactively as you go. Design ramps with complete control over grade, width, and number of switchbacks. Save the results as a design file and triangulation.

Evolution

This option provides the ability to read in the Evolution phases to allow more control over the period map creation.

Appendix A

This section lists the file naming conventions and provides examples of files used by the Open Pit module.

Appendix B

This section describes the various sections that may appear in the .smp parameter file. This file is used by the Sampling module (found under both the Geology and Open Pit menus), and the Blockout and Grade Control modules (under Open Pit). The Grade Control module is client specific.

Appendix C

This section explains the types of commands that may exist in a macro file (used by the Benching and Batters module) and provides a list of available commands together with any qualifiers.

Appendix D

This section provides a detailed description of the datasheet used by the Grade Control module, as well as information on how to utilise date stamping in the Grade Control module.
