Abstract/ Foreword

The paper describes the practical solutions and safety conditions of realizing the demolition of an industrial chimney and a cooling tower located in a former thermal power plant, having in the very close vicinity several civil constructions. The chimney has a height of 208 m and consists of the outer tubular structure of reinforced concrete and as well as of the inner chimney made of refractory brick masonry. The cooling tower height was 108.0 m and the base diameter of 82.00 m. For chimney, the chosen solution of demolition was overturn in an intended direction and for the cooling tower was that of partial lateral collapse followed by a total crash of the tower on its position. Considering the location of civil constructions the challenge of the project was to find solutions to reduce the throwing distance of the concrete pieces under the action of the explosion, to mitigate vibrations through the collapse and sequential contact with the ground of the construction, to reduce the value of the overpressure of the air created due to the piston effect during the collapse the construction of the tower.
