Profile

Five years’ experience in the Ghanaian Mining Industry mainly with Anglogold Ashanti, (formerly Ashanti

Goldfields Limited), Obuasi. Worked through the ranks to become a senior Geotechnical engineer

(Technical) at the South Mine section of the Obuasi Mine. Within these five years, I have had stints with the

Backfill department where our main type of fill is Hydraulic cyclone fill with and without cement, the database

and instrumentation management section of the department as well as work with development contractors

on major declines at the mine. I am in charge of three senior staff and four junior staff Technical team.

Acquired good management capabilities, communicational and interpersonal skills.

I am proficient in the design of underground excavations – Open stoping – Longitudinal and

transverse (designing based primarily on the stability numbers and calculated Hydraulic radii for

stope walls)

Sequencing of stopes also primarily based on schedule of filling of stopes

Planning and scheduling for instrument installation in stopes for monitoring crown and hanging walls

Preparation of Ground Control Management Plan (GCMP) in underground

Risk assessment and ICAM investigations

Mapping, Testing and Monitoring, data collection, storage and analysis

Design and Monitoring (QA/QC) of Reinforcement and Shotcreting

Backfill (Hydraulic fill) QA/QC

Laboratory testing for rock parameters (intact and rock mass), cement grout for cable bolts and

backfill bulkhead bricks.

Major Achievements / Accomplishments

I was part of the successful designing of portal support and all the support standards of the

mechanised decline at the Obuasi mine and subsequently all mechanised developments on

the mine.

I was part of the Geotechnical team that designed the shotcrete sup port for the decline portals

and the monitoring processes –, slump test, early strength and final strength test.

I am in the fore-front of all training at the Geotechnical department for all newly employed

engineers and mine supervisors – this includes Sirovision mapping, scan line mapping,

database analysis and instrument installation and monitoring.

I was part of the Geotechnical team that undertook ground penetrating radar systems to

determine the size and shape of voids under company housing in the village.

Required Experience

Experience in conventional and mechanized mining: I am experienced in conventional and trackless

(mechanised) mining in various types of stoping methods in different rock types for gold. I have experience

in Open stoping and Sublevel Caving.

Underground experience: I have spent the last five years of my life underground, going through the basic

systems of ventilation, backfilling, geology and production drilling but the chunk of my time has been with

the Backfill and Geotechnical departments. In summary, I have quite an appreciable underground

experience which will add value to any organisation.

Ability to achieve targets in respect of safety, production and costs: Mining is all about achieving

targets safely at the minimum cost. I have a comprehensive way of achieving targets by good planning

which involves all the stakeholders (ventilation, engineering, and other support services). At such planning

meetings, every element of all projects is identified and the possible issues are brought up. These are then

addressed in a timely manner so that the project could be executed on time.

When it comes to safety, one cannot assign a cost element to it. I believe in being very proactive and

ensuring that whatever it takes to ensure that all workings are safe for the worker are in place. That way

every person comes to work and go home to see the family without any injury or harm. In actual fact no one

wants to work at a place full of incidents or accidents. It is on record that any accident impacts negatively

on the company in the eyes of the public and other stakeholders.
