“…Some of the energy escapes into the atmosphere to generate air blast or air vibrations. Some of the energy also leaves the blast site through the surface soil and bedrock in the form of ground vibrations [1][2][3].…”

“…The biggest part of energy is being consumed on crushed mass spreading, heating of the environment, and other useless forms of work, such as the creation of the vibration/seismic waves ( Figure 1b) [1][2][3]6,7]. Waves of air vibrations and soil vibrations disturb the material and massif causing their movement when they encounter buildings or structures, causing their shaking.…”

“…Shaking of the ground surface has stronger or weaker intensity, which depends on the distance (r) and the quantity of explosive (Q) that is activated in a simultaneous time interval. Additionally, the intensity of shaking of the ground surface depends on the blasting method, as well as the physical and mechanical properties of the soil and the characteristics of seismic earthquake damping [2,3,4,10].…”

Determination of the blasting safety area is a very important step in the process of drilling and blasting works, and the preparation of solid rock materials for loading. Through monitoring and analysis of the negative seismic effects to the objects and infrastructures around and at the mine area, we were able to adapt the drilling and blasting parameters and organization of drilling and blasting operation according to the mining progress so that the affected infrastructures could be protected. This paper analyses the safety distances and model safety zones of drilling and blasting for the period 2013-2018 at the open pit at "Buvač", Omarska. This mathematical calculation procedure can be used during the whole life of the mine. By monitoring of the blasting seismic influence in first years of the mine's work, as well as by using recorded vibration velocities, mathematical dependence of the important parameters can be defined. Additionally, the level and laws of distribution and intensity of the seismic activity can be defined. On one hand, those are known quantities of the explosive and the distances between blasting location and endangered objects. On the other hand, those are coefficients of the manner of blasting and the environment where blasting is done, K, as well as the coefficient of the weakening of seismic waves as they spread, n. With the usage of the allowed vibration velocities, based on certain safety criteria and mathematical formulas of laws of spreading and intensity of seismic influence for a concrete case, it is possible to calculate explosive quantities and distances, with numerically-defined values of parameter K and n. Minimum distances are calculated based on defined or projected explosive quantities. Additionally, we calculate the maximum allowed explosive quantities based on known distances which can be used based on projected drilling-blasting parameters. For the purpose of the planning of drilling and blasting it is possible to define the allowed explosive quantities or minimum allowed distances in any area of the surface pit from the aspect of seismic safety. In the indicated case, and based on the analysis results, it is shown that in some areas of mining works in the case of the "Buvač", Omarska open pit, projected explosive quantities cannot be used. In some cases, it is even necessary to divide the explosive charge in blasting holes with additional delayers.

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.

“…Wherever back break has been the blasting problem in a new bench, the lower amount of back break is considered as the blasting pattern evaluation factor Gate et al 2005;Khandelwal and Monjezi 2012;Monjezi et al 2012;Monjezi and Dehghani 2008;Monjezi et al 2010b). In addition, a few endeavours have been made to diminish ground vibration (Erarslan et al 2008;Ak et al 2009;Hudaverdi 2012;Shuran and Shujin 2011;Bakhshandeh Amnieh et al 2012;Dehghani and Ataee-Pour 2011;Monjezi et al 2010a;Guosheng et al 2011;Ak and Konuk 2008;Iphar et al 2008;Monjezi et al 2011b). The essential issue of these examinations is to recognize stand out of the impact criteria in the blasting operation enhancement.…”
