Drilling and Blasting Technique

Course Description

Study program: Environmental Engineering (VI semester -OAS), Geophysics (VIII semester -OAS)

Name of subject: Drilling and Blasting Technique

Instructors: Dr Suzana Lutovac, Miloš Gligorić

Status: Optional


Prerequisites: -

Course Objectives: The objective of the subject is to familiarize students with the use of explosives. The educational contribution of the subject is in the knowledge of the exploitation of the energy of explosives in order to destroy the rock mass during exploitation of mineral resources.

Learning Outcomes: Training of students - future engineers for handling explosives


Theory teaching
The course content is divided into three parts: general part, drilling operations and blasting operations. The general part deals with the historical development of drilling and blasting operations, the working environment and the utilities necessary for the production of boreholes. In the part drilling operations, drilling processes, mechanisms and theoretical principles of rock destruction are given, then the important factors affecting the speed of drilling, tools and accessories for the production of boreholes, as well as the measures of protection during the construction of boreholes. In the part blasting operations, divisions and definitions of economic explosives are given, means and methods of initiating charges, as well as methods for testing explosives and ignition devices. Further, the theory of detonation, the factors that influence the rate of detonation, the mechanism of destruction of the walls, the construction and the production of the electric primers, and the methods for filling boreholes with explosives are discussed. Also, procedures and calculations for the determination of the optimum type of explosive and deceleration interval are given, as well as calculation of the specific consumption of explosives.

Practical teaching
Utilities. Getting to know the borehole equipment. Calculation of the basic influence factors on drilling speed. Getting acquainted with means for blasting. Calculation of the optimum type of explosive and deceleration interval. Calculation of specific consumption of explosives. Practical work with tools for drilling and blasting at the university mine in Avala. Field exercises. Visiting underground and open-pit mines.
