The use of mechanical devices such as chain flails for landmine neutralization and/or area reduction has the potential of greatly aiding landmine clearance. However, mechanical clearance methods have not been fully accepted in the landmine clearance community due to a lack of knowledge and scientific data concerning the actual soil-tool interaction and the landmine clearance effectiveness. The research objective was to develop a mechanical device that will deliver sufficient force to produce adequate ground deflection for detonating typical antipersonnel landmines at depths up to 200 mm. Other design parameters included design simplicity, high durability with low and ease of maintenance and flexible operation. A design matrix was employed to select an appropriate design for further analysis, resulting in preliminary testing and evaluation of a Tamper and Jackhammer. It was concluded that a tamper design resulted in superior demining capabilities. A final testing phase was designed on further evaluation of the demining effectiveness of the tamper and to determine optimal operational parameters between two shoe sizes and the number of pass applications. Tests were conducted using the Terra Mechanics Rig facility at the University of Saskatchewan. The results revealed that the small tamper shoe configuration performed better than that of the large shoe, but only marginally. Results also indicated the optimal application was two passes. It was concluded that the optimal shoe configuration would be associated with the demining environment where the device would be used.
