Analysis of fine fraction at rock destruction by explosion and formation of rock landslides

Article preview

The study of finely dispersed fraction of nano- and microscale size formed as a result of rock destruction by explosions of chemical explosives and rock slope collapse has been carried out. The possibility of formation of nanoscale particles from 20nm to 240µm in case of rock destruction by explosion and from 77nm to 2µm in case of rock slides is shown. Particles propagating in the atmosphere, formed in the explosion funnel and at the base of rock landslides are considered. Statistical analysis of the fine particle fraction by size is performed and compared with the classical Kolmogorov and Rosin-Rammler distributions. The peculiarities of the character of fine particles crushing depending on the size and type of rocks were analyzed.

Disruptive effect of an explosion in a pre-stressed environment

Article preview

Despite ongoing attempts to create new destruction technologies based on non-traditional approaches to mining (thermal destruction, exposure to radiation streams and high energy particles, etc.) the explosion of chemical explosives remains the main way of crushing rocks in the massif. It seems that in the coming decades, explosive technology will remain dominant on an industrial scale.

State, prospects and expert evaluation of the optimal size of the possible use of industrial explosives in Russia

Article preview

The basis for the work presented is the Resolution of the Interdepartmental Council on Explosives № 3 dated 10.12.99. A number of leading specialists of the country in the field of development, production and use of explosives (explosives) were involved in the preparation of materials.
