Recommendations on selecting optimized blasting supply scenarios in lode gold ore mining

The article justifies recommendations on selecting optimized blasting supply scenarios in mining small lodes of gold ore. The complications of such type ore mining are listed. There is a risk of deviation of actual mining performance from the project values. In such conditions, a subsoil user needs economically efficient design solutions. It is pointed at insufficient methodical framework for the justification of design solutions on explosives storage at different stages of small-size gold ore body mining. The average service conditions in mining such ore bodies are described. The gradient descent method allows selecting an optimized method of explosives supply. At the first stage of the method application, the discrimination of the basic, stringent and soft constrain is carried out on the ground of regulatory documents in effect. At the second stage, the constraint violation scoring is presented. At the third stage, each blasting supply scenario is a given a score per all phases of mining. As a result, specific recommendations are offered for a subsoil user to arrange and construct storage places for explosive materials. Furthermore, the recommendations on selecting optimized supply of blasting sites with explosive materials at all stages of small-size gold ore mining are given.
