The course Excavation, Blasting and Earthworks It is an opportunity to delve into the complex world of civil and mining engineering. In a constantly evolving market, it will provide the essential foundations for tackling various tasks related to the excavation and earthworks. Through four structured learning modules, participants will learn to identify sites suitable for excavation and to select the appropriate machinery and relevant equipment, as well as planning and plan blasting operations efficient, whether in open-cast mines or in tunnels. Whilst not claiming to be an advanced course, this course lays the foundations for understanding key procedures and technical criteria in these activities, which is vital for work safely and effective within the sector. The course focuses on providing a balanced mix of practical and theoretical knowledge, emphasising the importance of informed decision-making in projects involving earthworks.
