The airdeck blasting technique has been used in the past to reduce the explosive charge and to
improve the rock fragmentation. The mining and construction industry of Pakistan has always been
reluctant to use airdecks in their blasting operations. This is due to the fact that researchers and
practitioners have a divided opinion about the efficiency of this technique. The present research work
addresses the fundamental question regarding the technical and economic efficiency of the airdeck
blasting technique. A series of experiments was conducted using concrete blocks to find out the proper
position and optimized length of the airdeck. It is found that an improved rock fragmentation is
achieved when the airdeck is placed at the middle position of the explosive column. Moreover, it is
also observed that the mean blasted rock fragment size increases with the increase of airdeck size.
