This procedure details how to use the Trimble S6/S8 total station to complete routine underground surveying tasks including: standard station setup, resection, forward station establishment, feature surveys and extended rod drillhole surveys. The field procedure relies on the use of the GEMS_UGv2.0.xsl style sheet to export data from the TCU to allow straightforward processing in Gemcom Surpac using Geodat 600 data recorder function. Please contact us regarding implimenting its use. (460Kb PDF)

The purpose of this procedure is to describe the method to complete an automated prism monitoring with the Trimble S6 or S8 total station, in a typical open pit mining environment. The scope of this is document is for all mine sites using Trimble S6 or S8 total stations, in conjunction with SoftRock Quikslope software. (360Kb PDF)

The code of practice published by West Australian Mines Department at the time, for Mine Surveyors. Although only treated as a suggested guideline by many, at GEMS we incorporate all aspects of this document as part of our self-imposed Survey Standards. (510Kb PDF)

An Excel spreadsheet which queries the Quikslope database and tabulates and graphs data. The advantage of this addition is that this can be submitted to others, whether they be Geotechnical consultants or Managers for review, without the requirement for them to have Quikslope software and be familiar with its use. Please contact us regarding implimenting its use. (280Kb xls)

This calculator balances out, or reconciles/adjusts mining stockpile, loading, trucking, and milling figures. The adjustment is a weighted one, based on the precision of the input data.

Survey equipment used for baseline or other precise surveys should be maintained regularly and kept in good adjustment. EDM equipment used for precise surveys should be verified against the surface baseline at least once each year and immediately after service or repair. This log sheet (120Kb PDF) is for documenting the measurements.

A simple Excel spreadsheet for converting between GDA and MGA. Using Redfearn’s formula the (XLS 70kb) file was sourced from the Intergovernmental Committee on Surveying and Mapping (ICSM) web site — GDA Technical Manual and Transformation Software page. See www.icsm.gov.au/icsm/gda/gdatm/

This GPS user guide is a worthwhile read for those wanting a slightly better than average understanding. Found this on the NSW Dept. of Lands web site, where a download is available, as well as on our web site .

This MS Powerpoint show illustrates how the slicing (centreline, reference) line placement, and laser line markups can affect the actual collar position.

This is a log sheet aka survey station summary sheet for GPS readings on a point.

Prior to the WA Mine Survey - Code of Practice, and at the simular time of the NSW MR Directions for Mine Surveyors, at GEMS we documented a series of self-imposed standards which the team are at minimum to adhere to. This document undergoes revisions to continually "raise the bar". (200Kb PDF)

Although now superseded, it is a handy document that is often difficult to locate on government web sites. See items in it such as “dump construction that allows progressive rehabilitation” whilst the dump is being constructed.

This procedure describes a macro that has been made up to enable the re-calculation of survey station coordinates within a traverse ledger, to be more easily performed.
It applies to general mine surveying, and SSI v4.1 software.

This procedure describes how to check, and change some of the instrument settings for a Geodimeter 468DR. 
Without the knowledge of these settings, a surveyor may be caught out, and encounter problems with out some field work.
It applies to general mine surveying, Surpac software, and the Geodimeter 468DR style of instruments.

This procedure describes how to check, and change some of the instrument configuration settings in the Leica TCRA1103. 
Without the knowledge of these settings, a surveyor may be caught out, and incorrectly carry out some field work.
It applies to general mine surveying, Surpac software, and the Leica TCRA1103 style of instruments

This procedure describes a routine for post processing a free-station resection using SSI-v5.0, from field notes. 
The routine is not for any specific brand of survey instrument or data recorder, but rather for field book recorded angle and distance measurements.

It applies to Surpac Vision 5.0-A, for both underground and surface free stations or resection.

This procedure describes the steps required to complete a RTK Site Calibration.
This (650Kb PDF) document applies to all mine sites using Trimble 5700/5800 GPS Receivers with TSCe controllers, or later models.
The procedure also provides a tie-in of the local mine grid with the Australia national grid (MGA94) via surrounding SSM’s.
This document applies to all mine sites using Trimble 5700/5800 GPS recievers with TSCe controllers - or later models.

An Optec CMS (Cavity Monitoring System) survey produces a series of surveyed points outlining the actual shape of a void left by a stope, drive or some other opening.

The CMS is a useful tool to determine shapes of underground voids where conventional survey techniques would be considered unsafe.

Surpac software has a function which will create a 3dm (3 dimensional model, or wireframe) from the raw cms data.

Simply just using this function alone has several limitations:
1.    Its inability to see through an object such as a ledge on the hangingwall or rockbolts and mesh inside the stope or hanging down from the brow.  The resulting shadows require some interpretation to refine the model of the actual stope shape.
2.    The data sets are very large, often tens times more than what would be required of a final model.  Having several CMS survey data sets can often tax the speed at which some computer can process and display the data.

This procedure is based on using the Surpac Ring Design module to convert the CMS survey into a final model, and overcoming the above mentioned limitations.

The model of an actual stope shape can then be compared with the design shape to determine the location and quantity of any overbreak or underbreak that may have occurred. It can also be used to generate reports on the block model grade of both the overbreak and underbreak, a valuable tool when reconciling planned and unplanned dilution.

This procedure describes a way of using an Optec CMS (Cavity Monitoring System) to survey a stockpile, and process the data into a useable format in Surpac software.

This procedure applies to:
•    Any truck dumps, stockpiles, or pit wall scans.
•    Optec CMS equipment.
•    Surpac Software v4.1 and 5.0
A certain degree of prior knowledge of Surpac, surveying, and CMS processing is assumed.

These notes are compiled to assist in marking up an underground heading.
They should be applicable to all survey laser offsets, whether on a straight or a curve.

A pps training document has been compiled to acompany this procedure.

Based on the Australian Standards feature codes and industry adopted defaults, this is a listing that has been developed over the past decade.
Complying with such a listing enables data to be more readily recognised and used, when being passed around.

To be used in conjunction with:

AS 13567.2-1999 : Technical product documentation - Specifies the organization and allocation of layers for CAD on construction projects for the purpose of communication and management. This Standard is identical with and has been reproduced from ISO 13567-2:1998.

AS 4368-1996 : Mine Plans - This Standard sets out recommendations for the preparation of mine plans and the symbols to be used on all underground and surface mine plans
