A Study On The Formatıon Of A Model Of Mınıng Management Based On Geographıc Informatıon Systems

The environmental problems caused by ground vibration and air blast have been encountered and discussed frequently in various industries such as quarry, mining, civil works, shaft, tunneling, pipe line and dam construction etc. where the blasting operations are unavoidable. In bench blast design, the technical and economical aspects, such as block size, uniformity and cost should be taken into consideration as well as the elimination of environmental problems resulting from ground vibration and air blast. The prediction of ground vibration components plays an important role in the minimization of the environmental complaints

This study presents the results of ground vibration measurements induced by bench blasting carried out in the Akyol quarry at Çatalca. ANFO and emulsions as blasting agent and non-electric detonators as initiation system were used during bench blasting. The parameters of scaled distance (charge quantity per delay and the distance between the source and the station) were recorded carefully and the ground vibration components were measured for all blasts at this quarry by using White Mini-Seis and Instantel Minimate Plus model vibration monitors. The number of vibration monitors varied from 1 to 5, depending on the availability of these monitors. The absolute distances between shot points and monitor stations were determined by using GPS.

In order to determine the possible damage to the neighboring buildings, and structures at Akyol quarry at Catalca region, the particle velocities and frequency values of all blast events are evaluated according to the United States Bureau of Mines (USBM) and German DIN 4150 Norms due to the lack of a national standard in Turkey. Then, in order to predict peak particle velocity (PPV), the data pairs belonging to this quarry were gathered together to represent the region and were analyzed statistically. During this analysis, The equation of square root scaled distance extensively used in the literature was taken into consideration for the prediction of peak particle velocity. At the end of statistical evaluation of the data pairs, an empirical relation which gives average line at 95% confidence level and upper bound 95% prediction line with a powerful correlation coefficient (r=0,86) was established between peak particle velocity and scaled distance. By using this relationship, PPV and maximum charge amount per delay tables were prepared for practical usage in the future studies at this quarry.
