NON-EXPLOSIVE ROCK DESTRUCTION

The monograph presents theoretical and experimental studies of obtaining a non-explosive destructive mixture (NDM) from local raw materials and a method for separating monoliths from an array using a new composition of NDM, which makes it possible to silently split monolithic blocks, reduce the labor intensity of the work performed, ensure environmental protection, reduce the cost of production and energy intensity, mining operations, as well as to improve the safety of their conduct. A mathematical model has been developed for creating high internal pressure in boreholes when using NDM, which makes it possible to obtain an even detachment of rocks in the massif, the problem of obtaining a continuous straight line of cracks when using NDM in rocks has been considered, and a methodology has been developed for studying the new composition of NDM and rock samples in laboratory conditions. The monograph will be useful for teachers and students of mining universities and faculties, engineering and technical workers of mining enterprises, research and design institutes.
