Read the latest stories about EMerald Geomodelling and how we uncover ground conditions in large scale infrastructure projects.
Back in 2013, First Quantum Minerals Ltd (FQML) collected geophysical data to map the depth of saprolite and to characterize mineral deposits in relation to a mining project in Panama. EMerald Geomodelling assisted FQML in their project by using the unique interface detection algorithm to generate a detailed model showing the interface between saprolite and hard rock, providing inputs into saprolite elevation and resistivity.
RUMO Logística, the largest railway company in South America, has engaged EMerald Geomodelling in their latest project. By applying our innovative method of bedrock and soil mapping, they’re able to begin the project quicker and with less risk.
The industry needs to pick up the pace and accelerate the development of new technology for site investigations and design. Otherwise, we could be easily falling behind, according to one of the experts in the field, Alex Petty.
With new projects, new clients and new technology in the pipeline, 2022 will be a busy year for EMerald Geomodelling. To tackle the increased activity, the company is making organizational changes.
In the aftermath of the devastating quick clay landslide in Gjerdrum in late 2020, The Norwegian Water Resources and Energy Directorate (NVE) started conducting surveys to assess quick clay zones. EMerald Geomodelling was engaged to perform airborne geoscanning over an area in Nannestad, with the aim of effectively getting an overall overview of the ground conditions.
By combining a multitude of data points into a comprehensive 3D model, we were able to identify potentially significant conductors at three separate locations. The discoveries will be important for Kuniko going forward.
The data collected shows not only where quick clay is located, but also what to do. The method has received international attention.
Within three days, EMearald Geomodelling managed to map the ground conditions in a 500 km area. This gave the contractor more security in planning the road alignment of the massive road project.
Chris Pressdee is the newest addition to the EMerald Geomodelling team and will be assisting the company’s work in the UK. With his 25 year’s engineering experience, he will be a strong addition to the team.
For the first time ever, the rock conditions of the challenging Himalayas were mapped with the use of helicopter geoscanning and exploratory drilling follow-up. This pioneering work, done in 2013, made it possible to analyse the ground conditions in practically inaccessible areas.
For all big road and tunnel projects, knowledge of the ground conditions can be what makes or breaks it. Therefore, a thorough drilling campaign is required to get the necessary information before the construction work starts… Or at least, that's been true in the past.
Through innovative thinking, the team at EMerald Geomodelling has demonstrated that it’s possible to do large-scale mapping of quick clay occurrences by combining airborne geophysics, geotechnical investigations, and machine learning. A scientific study demonstrating this integrated approach has now been published in Near Surface Geophysics.
