Safety Improving of Mine Preparation Works at the Ore Mines


Main scientific and practical results of safety improving of mine preparation works at the ore mines are given taking into account the geoenergy of the underground mining of ore deposits by revealing the physical essence of the phenomenon of mine workings zonal encapsulation. Analysis of the method of preparation of iron ore reserves was carried out. The results of analytical, laboratory and industrial studies of the stability of chambers and mine preparation workings of the level-chamber mining filling system are presented, and the methodology for calculating the rational parameters for the preparation of production blocks at Prokhodcheskaya mine of ChAO Zaporozhsky ZhRK is developed. The essence of the methodology is that the backfill of the preparation workings should be rationally performed in places with similar or maximally reduced energy-saturated rocks. The extended and express methods for identifying the distance of drifts location from the ore deposits were developed, and these values were determined for the depths of 500–1500 m. Classification of methods is proposed related to studying the stressed-deformed state of rocks taking into account the effect of natural and artificial energy fields in the array. The efficiency of rationalization of mine preparation works at the plant is shown.
