“…Blast induced rock mass damage, defined as the propagation of inherent geological discontinuities and/or the formation of new cracks along weak planes in rock mass [8,9], is affected by both the controllable and the uncontrollable parameters [10,11]. The controllable parameters including mainly burden, spacing, stemming, subdrilling, and delay time can be optimized during blast design aiming at minimizing blast induced adverse effect, while the uncontrollable parameters are associated with the complex geotechnical characteristics of rock mass [12].…”

Blast induced rock mass damage and crack propagation play important roles in structure safety and stability in mining, quarrying, and civil constructions. This paper focuses on the effect of small blasthole diameter blast on crack propagation and damage accumulation in water-bearing rock mass containing initial damage composed of inherent geological discontinuities and previous multiblast induced damage. To elucidate this effect, theoretical analysis of calculation method for several important blast influencing factors is firstly presented. Secondly, definition of a practical damage variable using ratio of longitudinal wave velocity in rock mass before blast occurrence to that after blast occurrence and derivation of a damage accumulation calculation equation accounting for initial damage and blasting effect are described. Lastly, a detailed description of the conducted in situ blast tests and plan layout of the sonic wave monitoring holes is reported. The results indicate that blast activates and then extends the initial cracks in rock mass, leading to accumulation of rock mass damage. The rock mass damage accumulation can be conveniently quantified using the proposed damage variable. When the damage variable reaches its threshold of 0.19, occurrence of damage in the surrounding rock mass is indicated. It is also found that the blast induced rock mass damage extent and the blast induced vibration velocities decrease nonlinearly with increasing the distance between blast source and monitoring position.

“…The overall costs of mining, quarrying and construction activities are significantly influenced by the degree of fragmentation, displacement and looseness of the muckpile that has to be transported. In the blasting operations, a large amount of explosive energy is utilised in creating undesirable environmental impacts like generating flyrock, blast-induced ground vibrations, air-overpressure, and back-break which can affect the surrounding area [1][2][3][4][5]. Among these, the blast-induced ground vibrations are recognized as the most undesirable phenomenon which may lead to damage the surrounding structures, adjacent rock masses, roads, underground workings, slopes, railroads, the existing ground water conduits, and may cause irreparable damage to the ecology of the surrounding area [6][7][8][9][10].…”

One of the most important operations in mining is blasting. Improper design of blasting pattern will cause technical and safety problems. Considering impact of results of blasting on next steps of mining, correct pattern selection needs a great cautiousness. In selecting of blasting pattern, technical, economical and safety aspects should be considered. Thus, most appropriate pattern selection can be defined as a Multi Attribute Decision Making (MADM) problem. Linear assignment method is one of the very applicable methods in decision making problems. In this paper, this method was used for the first time to evaluate blasting patterns in mine. In this ranking, safety and technical parameters have been considered to evaluate blasting patterns. Finally, blasting pattern with burden of 3.5 m, spacing of 4.5 m, stemming of 3.8 m and hole length of 12.1 m has been presented as the most suitable pattern obtained from linear assignment model for Sungun Copper Mine.
