Prediction of UXO's Penetration Depth Using Numerical Simulation Bomb Trajectory with Case Study

About a quarter of a century has passed since the IRAK-IRAN war but unfortunately، some areas of the country still remains contaminated by mines and unexploded bombs and sometimes irreparable damage is inflicted. Due to the limitation of magnetic mine detectors، penetration depth should be estimated with reasonable accuracy. In this paper، the mathematical model of the bomb motion in the air and soil is written. The bomb motion is simulated based on TM and military handbook with MATLAB. Then UXO penetration depth in Azadegan oilfield was Investigated as a case study and simulation results are compared with MIZUHO results. The effect of the bomb angle of attack in the penetration depth is also determined. Finally، regarding all effectives parameters، the correct depth is estimated and invalidity of MIZUHO results is shown. Subsequent excavations carried out in the field and non-observation of UXO in more than six meters deep proved obtained results.
