The most influencing the stopes walls stability factors have been determined. Physical-and-mechanical ore mass properties impact to the stopes height has been researched. Advanced ways to improve stopes walls stability have been considered.
The analysis of actually developed technological scheme of Jakovlevsky mine is made. The basic directions of perfection of existing technology of working off for-passes, promoting increase of capacity and decrease in costs proiz-vodstva ores are offered. The further direction of researches which will allow oprede-pour rational, a relative positioning clearing заходок in fulfilled layers and para-metres of technological schemes of joint dredging of layers is con- sidered.
Mining systems for ore bodies of different thickness are developed for the conditions of Cholodninskoe deposit. Ration parameters of mining system are determined.
Research of cutoff grade influence on economic performances of mine as well as parameters and configuration of ore deposits with the help of the advanced geoinformation system were carried out. Computer modeling of an ore chute was made; the results of calculation were presented, involvement is given.
A complex of technology and organization methods to higher grade filling due to horizontal layers system of extraction rich ferrous metal ores for various stages of mining is presented.
