This paper presents a numerical investigation of the dynamic response of a non-contact gas-detonation mine clearing device structure subjected to the combined effects of detonation products and soil ejecta generated by the explosion of a buried TM-62 anti-tank mine, one of the most dangerous threats in contaminated areas of Ukraine. The simulations were performed in LS-DYNA using the Arbitrary Lagrangian-Eulerian approach, which provides an accurate representation of the coupled interaction between the detonation gases, soil particles, and the mine clearing device structure. A detailed three-dimensional model was developed, incorporating the mine, ground, air domain, and all structural components of the mine clearing device, to analyse blast scenarios at burial depths ranging from 0 to 250 mm. The results demonstrate a non-linear influence of the burial depth on structural loading: at shallow depths, a slight increase in impact load is observed; at intermediate depths, partial attenuation occurs due to lateral energy dissipation; and at greater depths, energy accumulation in the soil produces an intense upward jet that markedly increases loading on the structure. The obtained data on loading levels and on the structural areas most affected by shock-wave impact and soil deposition form the basis for developing a strategy for further design improvement and modernization of gas-detonation mine clearing devices.
