THEORETICAL FOUNDATIONS FOR RATE RAISING OF UNDERGROUND DRIVING BY HOLE BLASTING MANNERS AT PIT AND AT MINES

Abstract

There the purposes are to develop the theoretical foundations to raise the rate of driving by the hole blasting manner, to predict the characteristics of machines, to organize the works at the face. The methods of mathematical simulation and of prediction of characteristics of face machines, of hole blasting for the major decrease of labour-intensiveness of driving have been developed. The developed methods were used at the enterprises and in the design institutes to substatiate the technical and organization approaches of high-rate evolution of driving, which were accepted for use, to create the outlook number of face machines. The manuals and the instructions to raise the rate of driving by the hole blasting manner are used at the pits and at the mines. 6 standardizing documents to raise the rate of driving and to improve the hole blasting have been developed and have been introduced. The application fields are the pits and the mines (the driving in the tough rocks)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
