Opis:: The paper presents a system that is a worldwide-unique means designed for building engineering barriers, fitting into the quasi-intelligent battlefield concept. The weapons employed are an innovative solution that integrates acoustic, seismic, thermal and laser scanner sensors into a single quasi-intelligent decision-making system. The system enables deploying a minefield section which, after deactivating 1st and 2nd degree safeties, operate autonomously, selecting targets and eliminating them with an explosively formed projectile. The paper presents the concept of the system's design and results of tests of individual elements.
Streszczenie. W pracy zaprezentowano system, który jest niespotykanym w świecie środkiem przeznaczonym do budowy zapór inżynieryjnych wpisującym się w koncepcję quasi-inteligentnego pola walki. Zastosowane środki rażenia są innowacyjnym rozwiązaniem, które integruje w jeden quasi-inteligentny system decyzyjny czujniki: akustyczne, sejsmiczne, termalne i skaner laserowy. System umożliwia ustawienie odcinka pola minowego, które po wyłączeniu zabezpieczeń I i II stopnia działają autonomicznie wybierając cele i niszcząc je wybuchowo formowanym pociskiem. Praca przedstawia koncepcję budowy systemu oraz wyniki badań poszczególnych elementów.

Opis:: This paper describes the initial model of the load-mine-ground relation and presents the preliminary results of a computer simulation. Pressure mine-clearing devices, with discs loosely embedded on the axis of the minesweeping section, (disc mine-clearing devices) cause deformation to the mine 's firing mechanism, which, through the actuation of the fuse, leads to the detonation of the inner-placed explosive. It is assumed that under the load of a mine clearing vehicle, the active part of the mine's cover will be vertically displaced by 6-10 [mm] actuating the fuse of the mine. Although the construction parameters of pressure mine-clearing devices are known, there is a shortage of instructions and data requisite for proper construction and effectiveness examination of dynamic mine-clearing vehicles. In fact, during mine clearing with a dynamic mine-clearing device, the force exerted upon the mine (Ngr) is that of the pressure by the disc (an element of the device). This force differs from a static load and the differences result from the following factors: mine placement type of soil as well as its physical and mechanical properties construction properties of a mine-clearing device pace of mine clearing The issue of influence transferred from the surface of the ground onto the mine placed inside is not present in literature and it constitutes an interesting and important scientific issue in terms of selecting parameters for dynamic minesweeping devices. Similarly to a static load, shock waves propagating within the ground cause its volumetric and structural deformations. The main cause of the differences lies in the briefness of a dynamic load. The gradual growth of static loads (clenching) causes displacement of air and water in the pores and their partial squeezing out. In the case of a static load applied to sandy soils, the process lasts from a few minutes to a few hours, whereas in the case of clay and loessial ones, it extends to a few days, weeks or, sometimes, even months. Under static and dynamic loads, the ground reacts similarly to a three-component centre with a changing-with-time amount of air and water. The action time of a percussive load extends from a few to between ten and twenty milliseconds. Due to air and water inertia, this is too short a period of time to squeeze them out of the pores of the soil, which reacts in a way similar to a three-component centre with a constant amount of air and water. Since in unhydrated soils the main part of the pores' volume consists of air, both static and dynamic loads are accompanied by the absorption of the main stresses by the skeleton. With static loads exerted upon the hydrated soil, both water and air flow loosely out of the pores without the absorption of the loads. In terms of strength the only working element here is the ground's skeleton. In the case of short-lasting, intense loads, water (with a small amount of trapped air) will not flow out simultaneously with the skeleton and, as in the case of mean pressures, it may absorb the load to a larger extent than the skeleton itself. The way the hydrated ground reacts to low pressures - below 1 MPa - is therefore largely determined by the amount of air in the pores. Therefore, the ground with a mine placed inside is a multiphase center with changeable properties - the semi-limited area with mechanical properties changing with each cycle of dynamic influence put upon its surface. Although the issue of the ground pressure measurement is dealt with in various publications, there is a lack of data concerning how it changes under the mechanical influence of moving vehicles and under that of dynamic minesweeping devices - the problem which is essential for a safe minefield crossing. The effectiveness of percussive minesweeping devices can be evaluated upon the basis of the experimental data obtained by means of measuring equipment. The elaboration of a reliable ground-mine relation model for short-time (percussive) influences transferred to the ground surface should accelerate the process of selecting parameters for dynamic mine clearing in terms of obtaining the maximum destructive impact, either directly upon the mine or through the actuation of its firing mechanisms for various types of mines, different depths at which they are buried as well as for various soils with their different properties. The above task is the aim of further works focusing on the subject presented in this paper.
