Our Specialty

Global Mine Design (GMD) provides best practice geomechanics services to underground and open-pit mines to optimise production-planning decisions.

Our Approach

At GMD our philosophy is data-driven decision making. We use, develop and promote new technology across our work to capture, analyse, and interpret the behaviour of ground material under operating conditions.

Once we've characterised the ground behaviour, we let you know how to use this information to fine tune your mine plan. Our approach increases confidence within the production team and by nature reduces unnecessary rehabilitation costs, brings efficiency improvements, and reinforces safe working conditions.

Our History

GMD was borne from a passion to understand the behaviour of soil, rock, and manmade ground material. Our foundation lies in being able to distinguish influential ground properties and communicate their effect on mining and civil engineering projects.

Working With You

Our goal is to continually optimise your operational mining strategy by determining how ground conditions will evolve during extraction. This information is invaluable for creating safe, timely, and economic plans.

When we work on feasibility studies, our expertise will get your mine to operational status with a clear view of the potential geomechanical challenges that lie ahead and the protocols to help mitigate them.

Our People
Phil Earl - Technical Director and Chief Engineer

Phil Earl

Phil is a geotechnical engineer with over 20 years of post-graduate experience. His interests centre on the application of geomechanics, including applied seismology, to mine design and planning. Phil established Global Mine Design in 2013 in order to concentrate on developing tools and techniques that allow mine site personnel to make educated decisions on the state of their orebody when production planning.

Prior to this, as a graduate from Camborne School of Mines, and Western Australia School of Mines, Phil held operational roles on large civil engineering projects across the UK and Ireland, and mine sites in Australia and Canada. For his last employer, Phil travelled extensively throughout the company mines in North and Central America to share his geomechanics knowledge, developing a reputation for challenging historical routines through the use of advanced data analysis. His achievements in this field later won him and his team an Excellence Award for advancing the company's strategic objectives in improved economic mine planning.

Brian Wissent - Principal Mining Engineer

Brian is a Professional Engineer registered in the Canadian Province of Ontario with over ten years of hard rock mining engineering experience. Brian graduated from Dalhousie University in 2007 with a BEng in Mineral Resource Engineering. Upon graduation he worked at David Bell and Williams Mines, within the Hemlo mining camp in Northern Ontario, Canada. He has also worked at Goldcorp - Musselwhite Mine and US Gypsum - Little Narrows Mine.

Brian specializes in mine design and planning and has specific expertise in cut-off grade analysis, Life of Mine scheduling, reserve and resource estimations, mining method selection and optimization. Brian also has experience with design, procurement and installation of underground seismic monitoring systems and the integration of seismic data into mine design. Brian has worked on underground backfill research projects, which included instrumenting stopes during pastefill pours to measure the in-situ backfill strength, reducing binder content through the use of admixtures and designing cemented rock fill delivery systems.

Nicola Wilton - Business Support and Copy Editor

Nicola initially trained as a Hydrogeologist, starting her career with the UK environmental regulation agency.  Holding an undergraduate degree from Camborne School of Mines and a postgraduate degree in Hydrogeology from Reading University, Nicola later took hydrogeological contract work in Africa before moving to Perth, Australia in 2005 where she worked as a hydrogeological consultant on large-scale mining projects.

 In 2008, Nicola moved within her company to set up a new office based in Sydney, New South Wales.  This experience exposed Nicola to business skills and in 2011 she moved to Canada to work for Barrick Gold as Business Support Analyst.  Managing a capital budget of around $50M she liaised between corporate  and site management, and advised site personnel on supply chain and accounting issues. 

As well as providing project administration and business support to GMD, Nicola is a qualified proofreader and member of the UK Society for Editors and Proofreaders (SfEP) specialising in the review of scientific and technical documents.

Stephanie Green - Designer

Stephanie is a Senior Designer with over 12 years experience in the publishing industry. Stephanie became Circulation Director of an international publishing house at the tender age of 23, always first to get stuck in and work until a job is done.

Having worked in a variety of roles from production, marketing, to design and printing. She has that rare combination of artistic talent, marketing know-how and broad business experience.
