A RESEARCH INTO AN ARRAY AND BASIC PARAMETERS OF THE DEVELOPMENT SYSTEM FOR COMPLEX STRUCTURAL FACING STONE IN UZBEKISTAN

The scientific paper has investigated a range and parameters of the block stone mining system in Uzbekistan. Scientific researches, made by leading scientists in this field, have been closely reviewed. Methods of assessment of fracturing and blockiness of massif based on correlation between linear and area indices of natural separations in massif have been applied. A technological scheme of face orientation in relation to fracture systems has been developed. Possible technical productivity of stone blocks extraction using different methods of preparation for excavation has been determined. Rational areas of various methods of stone block preparation for excavation and optimum technological parameters are established.
