This paper describes the controlled demolition of a reinforced concrete water tower located in an industrial area in Lugoj, Romania. Due to advanced structural degradation and high rehabilitation costs, demolition was selected as the most viable solution. The adopted method combined blasting works with conventional preparatory operations, using a controlled toppling technique in a predefined direction. A detachment wedge was created by drilling and charging 196 boreholes arranged in eight horizontal rows, initiate...

EVALUATION OF SEISMIC EFFECTS OF BLASTING IN UNDERGROUND SALT MINES

(STEF92 Technology, 2026, Ilie - Ciprian Jitea, Cristian Radeanu, Ewdward Gheorghiosu, Bogdan Garaliu-Busoi, Mircea Grecea)

Blasting operations are an essential part of underground mining activities, but the seismic waves generated during detonation may adversely affect the stability of underground mining structures such as galleries, chambers, intersections, and support systems. Repeated blasting can lead to cumulative damage, increasing the risk of degradation of both the rock mass and the installed support. This paper presents considerations regarding the assessment of the seismic effects of blasting operations on underground mining...
