Blast Design

Integrated on-site blasting services

For about 25 years, EPC Groupe’s have proven their ability to take up the challenges of a profession in which performance is key to success.

Whether supplied as an independent service or integrated in a global blasting service, blasting is a fundamental link in the production chain of the construction site, mine or quarry, either on surface or underground. Its adaptation to the specific conditions of the site and to the operation’s objectives requires both a capability for mobilising resource and strong technical expertise. In addition to the provision of our high quality range of explosives, we have the expertise and knowledge needed to modify blasting parameters to ensure ongoing improvements in blast operations.

Our teams of engineers, technicians and experienced operators, located in some 20 specialised subsidiaries across Europe, Africa and the Middle East, are equipped with state-of-the-art tools and technologies and have been successfully providing a wide range of services for a quarter of a century, including face profiling, environmental assessment, blast design, borehole loading or full ‘rock on the ground’ services.

Safe & Controlled Blasting

On-site safety is a major focus in the development of our blasting activities, EPC Groupe has been developing throughout the years various technologies that allows to deliver advanced productive solutions to our large customer portfolio across more than 25 countries.

One of these technologies is our 3D software, a blasting application designed by miners for miners. The EPC Groupe has compiled in this software all of the expertise of its engineers and technicians. The software allows the integration of 3D profiles, whatever the system or technology used to survey it (lasers, digital photogrammetry, drones). From this geometrical data, the holes can be modelled, including tilt, depth, and azimuth so that drilling can be completed accurately.

The drilling logs and report can be embedded into the 3D software, gather all the information related to a blast in a single database, to serve as a basis for the design of the loading and firing sequence.

EPC Groupe blasting service includes a thorough checking of the exact coordinates of the drilled holes (GPS positioning, inclinometer sensor). Thanks to the 3D software, the geometric information and field data are gathered and re-conciliated allowing our engineers to establish safe fire plans, guaranteeing optimum mass distribution, while respecting the environment by limiting the vibrations.

A hole-by-hole loading plan for safe and optimum mining is issued through the 3D software. All blasting plans are incorporated into a global topographic model for continuous tracking of the mining activity.
