This paper presents a predictive model based on gene expression programming (GEP) for estimating ground vibration produced by blasting operations conducted in a granite quarry, Malaysia. To achieve this aim, a total number of 102 blasting operations were investigated and relevant blasting parameters …

Blasting is a widely used technique for rock fragmentation in opencast mines and tunneling projects. Ground vibration is one of the most environmental effects produced by blasting operation.
Shot Rock Shot Rock is the unprocessed source rock utilised by the quarry's crushing plant. It is formed by drilling and blasting the basalt deposit and is usually supplied from the freshest and bluest rock unless otherwise specified.
the blast patterns calculated by empirical formulas to quarry blasting - patterns producing satisfactory results, with geology considered in the blast designs.
The rock mass in the entire quarry was classified into three types for a blasting pattern design based on 3-D spatial distribution of the rock factor estimated by the SIS technique. Table 3 shows the range and representative values for rock factors for each rock mass type.

Vibration measurements for 3 types of quarry rock at a number of sites in Thailand have been carried out and analyzed. The domi nant vibration parameters in bench blasting are based on the peak par ticle velocity and the blast frequency.
The frequencies created during a blast depend largely on the nature of the rock between the blast and the monitoring point, but also on the distance from the blast, the blast initiation sequence, and the way
The Guidelines for Ground Vibration and Airblast Limits for Blasting in Mines and Quarries (the guidelines) do not apply to control of impacts at commercial or industrial premises where less stringent standards may be appropriate.
