  7. Abstract:
  8. Explosion in soil medium have been a favourite topic for researchers From many years ago. however Most of researchs studied the impact of surface explosion on Perimeter environment (like mine explosion) and effect of the parameters like soil material and water content on pressure waves progressing inside of soil have been lees paid attention. In present work firstly we derive the data necessary for soil dynamic response computer modelling using different soil models from various resources. Then the impact of surface explosion will be investigated soil internally, using Ansys Autodyn numerical modelling. Results show that with an increase in soil water content, pressure wave peak overpressure increases. On other hand, adding clay to sand lead to overpressure increase. Also adding gravel to sand lowers overpressure. At the end of the research a quantitative and qualitative study on blast hole shape has been done
