ABSTRACT

Blasting is only the first step in the production process for mines and quarries and the cost of which is normally 8% to 12% of the total costs. Hence, reduced blasting cost is one of the main objectives of production blasting at a cement quarry. This paper presents the development of a prediction model for blasting cost per ton at Deewan cement quarry operations, located in Hattar, Pakistan. The dataset primarily consisted of a total of 12 parameters which has been analyzed using Principal Component Analysis (PCA) to account for most significant parameters. These parameters were then subsequently used to formulate a model for the prediction of blasting cost per ton in the cement quarry operations. The prediction model based on 5 statistically significant variables explains 88.1% of the variance while estimating the blasting cost per ton.
