Description:
JOB PURPOSE
-The purpose of the job function is to establish all necessary geotechnical parameters required, to determine if a identified mineral reserve / resource area can be mined by the companies actual mining systems in an economical manner.
-Engineer, in conjunction with the technical team, production enhancing methods on the actual seabed crawler system which can increase the hourly mining rate output.
-Engineer’, in conjunction with the technical team, a crawler excavation system which can be used in mineral reserve areas where the actual geotechnical soil conditions are adverse to the actual mining system and require an additional mechanical cutting and loosening device to enhance the excavation / mining process.
Managing the geotechnical department and supervising the geotechnical assistants.
DUTIES AND RESPONSIBILITIES SHALL BE BUT NOT LIMITED TO THE FOLLOWING:
Lab Analysis:
Submit samples to geotechnical laboratories (Geoscience labs, Rock labs, etc.)
If possible, perform one or two samples with laboratory to check results and confirm QA/QC of lab
Able to perform geotechnical laboratory testing, i.e. particle size analysis (fine sediments), oedometer, direct shear and triaxial shear, plastic and liquid limit (Atterberg tests), unconfined compressive strength (UCS) with absorption, point load index strength, rock petrography, and CT-scanning (voids and permeability)
Sampling vessel: and other exploration works
Supervise and train assistant geotechnical engineers
Manage the collection and organization of data
Perform geotechnical tests on clay, rock and sand samples (i.e. IRS and GSI, penetrometer and shear vane on clays, sieving, density, etc.)
Data capturing of geotechnical tests and sending information to Head Office
Photograph sample testing (before and after)
Assist, note and discuss geology (based on geotechnical observations) with screen logging geologists
Process and analyse drill tool trends with inhouse software and send processed information to Head Office
Create maps of footwall (types and based on clay shear strength or IRS in the case of rock)
Report on any findings regarding adverse stratigraphical conditions, based on observations from drill tool and tool trend findings (short weekly/summary report of important observations - geological and geotechnical related)
Create/aid new templates and ''operating manuals'' for procedures/tests
Office and Data Management:
Analyse data from laboratories and vessel – i.e. QA/QC data
Determine mechanical specific energies for both sampling and mining vessels
Model and grid processed data through Rockworks, Global Mapper and ArcGIS - geotechnical model of a mining area
Conceptualise and determine mining rates based on geology and modelled processed data
Reporting (hard copy and soft copy) of processed geotechnical data and update mine geologists with digital data (i.e. gr
