An Application of Fuzzy Sets to the Blastability Index (BI) Used in Rock Engineering

Abstract: Rock masses have inherently different resistance to fragmentation by blasting. This property is hereafter referred to as the blastability of a rock mass. Empirical models for the estimation of blastability have been developed. In this study, the Mamdani fuzzy algorithm was used to express the blastability index by fuzzy sets. We use Lilly and Ghose blastability models which are important models of blastability. Parameters of these models were represented by fuzzy sets as the input variables of the fuzzy model.… Show more

“…erefore, the effect of this single index evaluation method is not ideal. e second category uses soft mathematical calculation methods such as set pair analysis, neural network, cluster analysis, matter element extension method, and gray correlation analysis for comprehensive blastability classification [11][12][13][14][15][16]. Zhou et al [17] proposed a multifactor index system of rock mass blastability consisting of density, wave impedance, uniaxial compressive strength, and uniaxial tensile strength.…”

“…In Aref's study, the fuzzy algorithm was used to express the blastability index by employing fuzzy sets. Fuzzy BIs have more adjustment than conventional BI models [11]. Esmaeili et al analyzed the factors affecting rock fragmentation by Principal Component Analysis (PCA) and established a prediction model based on Support Vector Regression (SVR) and Adaptive Networkbased Fuzzy Inference System (ANFIS).…”
