Within the work, the basic information about mine blast phenomenon and its influence on the crew of special vehicles were gathered and discussed. The necessary use of blast mitigation seats was indicated and the basic methods for testing their efficiency were presented. A seat without shock attenuation system was examined. The conducted research allowed for determination of the acceleration levels measured at selected points. It was noticed that even without shock absorbing system, the seat is capable of mitigating some amount of incoming energy due to plastic deformation. However, it was not enough to lower the acceleration to a human tolerable level. This highlights the need for shock attenuation system implementation and optimization in order to minimize the acceleration transferred to the passenger. The obtained results provide a basis for further work in this area. The gathered signals were compared with literature data describing vehicle acceleration during mine blasts. The drop-tower used during the study proved to be suitable for explosion impact simulations.
