Solid medium controlled blasting technique and its applications

摘要

The purpose of the Solid Medium Congtrolled Blasting Technique and Its Applications is to have the inside of the vessel-shaped framework (e.g: oil tank, water pool, gas chamber, chimney, water toware, grain warehouse and etc.) or the one side of the thin wall-shaped structure(e.g: steel bar concrete wall and etc.), both of which are intended to be demolished, inserted with the required solid medimum (e.g: soil, sand, coal, salt and etc.), in which there is a certain mass density, and then through which the blasting energy is transferred to fulfill the blasting task. For such a technique, it is necessary to bury the explosives into the inserted solid medium and then to start the explosion to blast the intended target into pieces. The filling of the solid medimum may be done mechanically or by man. Compared with the water pressure blasting technique, this one has the characteristics of good effect. wide application, simplified construction procedure, safe and reliabile operation and small vibration (less vibration than water pressure blasting by 80
