Аннотация:
In order to provide the most efficient indices of development of underground excavations the main attention is
paid to blasting operations, namely, to determination of optimum parameters of drilling and blasting operations.
Development of new and reconstruction of existing mines require for extended scope of excavating works, their length can
reach some tens of kilometers. Up till now excavations at most of mines are developed using drilling and blasting
operations. Improvement of drilling and blasting operations is one of trends to increase efficiency of excavation
development. Reliability extent of calculated parameters of drilling and blasting operations can influence on technical and
economical performances of excavation development. At present numerous existing procedures are empiric dependencies,
they are based on primary determination of specific consumption of explosive. The main drawback of such procedures is
the application of coefficients of specific consumption, which vary in wide range, their values depend on the qualification
of experts who perform such calculations. As a consequence, the parameters of drilling and blasting operations are set on
the basis of averaged values, which impair efficiency of blasting operations. We believe that calculations of parameters of
drilling and blasting operations should account for the most complete range of factors playing important role in impact of
blasting energy on destructing massif. In addition, the proposed engineering approach should enable improvement of
efficiency of blasting operations with desirable decrease in material and non-material expenditures. This work describes
briefly tock destruction by blasting of explosives, highlights main factors influencing on efficiency of drilling and blasting
operations upon development of excavations. The work analyzes calculation procedures of main performances of drilling
and blasting operations, recommendations are given for development of pattern of drilling and blasting operations on the
basis of calculation of destruction zones of rock massif.
