Improving methodology of monitoring geomechanical behavior and property transformation in rock mass toward safe and efficient geotechnology

Mineral mining mostly features a trend of worsening of geological conditions due to increased variability of structure and strength properties in rock masses. The lack of online methods to acquire reliable information brings a problem connected with the subjective overevaluation of powder factor and intensity in drilling and blasting, which ends with failure of perimeter blasting, intense induced fracturing, instability of rocks, and with technological violations and complications. In this case, profitability of mining drops due to direct cost escalation, complication of geotechnology and decreased safety. Furthermore, flattening of pitwall slopes because of excessive powder factor leads to extra loss of active areas in open pits, which reduces production output per each meter of mining front. In this manner, rock mass variability and low integrity of monitoring methods make it impossible to distinguish the geomechanical component in inefficiency of mining systems, which impairs geomechanical safety and weakens geotechnology performance. Under the circumstances, it is very urgent to create objective methods of geomechanical monitoring and analysis toward enhanced safety and efficiency of geotechnology. This article describes some approved decisions on methodology and software/ hardware systems for geomechanical monitoring and analysis in the course of mining.

Keywords: monitoring of geomechanical behavior and property transformation in rock mass, pitwall slope flattening, blastability zoning, geomechanical safety and efficiency of geotechnology, induced fracturing, powder factor and drilling intensity.
