چکیده
Abstract Blasting is widely employed as an accepted mechanism for rock breakage in mining and civil activities. As environmental side effect of blasting, flyrock should be investigated precisely open-pit operations. This paper proposes a novel integration artificial neural network fuzzy cognitive map (FCM) with Z -number reliability information to predict distance mine blasting. The developed model called the causality-weighted networks, based on (ACWNNsR). -numbers used eliminate uncertainty expert opinions required initial matrix FCM, which one main advantages this method. FCM calculates weights input neurons using nonlinear Hebbian differential evolution algorithms. Burden, stemming, spacing, powder factor, charge per delay are parameters, output parameter. Four hundred sixteen recorded basting rounds from real large-scale lead–zinc design architecture models. performance proposed ACWNNsR compared Bayesian regularized multilayer perceptron proven result more accurate prediction estimating blast-induced distance. In addition, results sensitivity analysis conducted effective parameters determined spacing most significant parameter controlling Based type datasets study, presented recommended surface mines where buildings close blasting site.

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....
متن کاملImplementation of Hyperbolic Tangent Function to Estimate Size Distribution of Rock Fragmentation by Blasting in Open Pit Mines
Rock fragmentation is one of the desired results of rock blasting. So, controlling and predicting it, has direct effects on operational costs of mining. There are different ways that could be used to predict the size distribution of fragmented rocks. Mathematical relations have been widely used in these predictions. From among three proposed mathematical relations, one was selected in this stud...
متن کاملApplication of simulated annealing for optimization of blasting costs due to air overpressure constraints in open-pit mines
Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be controlled and optimized. The design parameters include burden, spacing, hole length, hole diam...
متن کاملAn Uncertainty-based Transition from Open Pit to Underground Mining
There are some large scale orebodies that extend from surface to the extreme depths of the ground. Such orebodies should be extracted by a combination of surface and underground mining methods. Economically, it is highly important to know the limit of upper and lower mining activities. This concern leads the mine designers to the transition problem, which is one of the most complicated problems...
متن کاملZ-Cognitive Map: An Integrated Cognitive Maps and Z-Numbers Approach under Cognitive Information
Usually, in real-world engineering problems, there are different types of uncertainties about the studied variables, which can be due to the specific variables under investigation or interaction between them. Fuzzy cognitive maps, which addresses the cause-effect relation between variables, is one of the most common models for better understanding of the problems, especially when the quantitati...
