This outcome may contribute to the knowledge of rock blast management by enriching the parameters selection for future blast design refurbishment. The previously stated project aim can be solved by tackling these specific objectives stated which is toDrill and Blast Parameters Table 1 shows the drill and blast design parameters as obtained from each blast event. The powder factor varies from 0.34 to 0.43 3kg/m while the quantity of explosive detonated per blast hole varies from 54.91 kg to 67.73 kg. All the six blast events have same burden of 3.5 m and a constant subdrill of 1 m.PRELIMINARY ASSESSMENT OF THE EFFECTS OF BLAST DESIGN

A new technique to predict fly-rock in bench blasting based on
Fly-rock caused by blasting is one of the dangerous side effects that need to be accurately predicted in open-pit mines. This study proposed a new technique to predict the distance of fly-rock based on an ensemble of support vector regression models (SVRs) and Lasso and elastic-net regularized generalized linear model (GLMNET), called This research was aimed at developing a new model to predict flyrock distance based on a genetic programming (GP) technique. For this purpose, six granite quarry mines in the Johor area of Malaysia were investigated, for which various controllable blasting parameters were recorded.

Evaluation and prediction of flyrock resulting from blasting
Mines, quarries and construction sites face environmental impacts, such as flyrock, due to blasting operations. Flyrock may cause damage to structures and injury to human. Therefore, flyrock prediction is required to determine safe blasting zone. In this regard, 232 blasting operations were investigated in five granite quarries, Malaysia. Authors such as Faradonbeh et al.
