PURPOSE: A mine-resistant protection kit of a special vehicle is provided to efficiently disperse the explosion pressure of a mine, thereby preventing physical impact caused by an explosion of the mine from being delivered to the special vehicle without an exclusive increase of weigh. CONSTITUTION: A mine-resistant protection kit(10) of a special vehicle comprises an outer material(21) and an inner material(22). The outer material contains 0.1-0.3% of C, 0.6-0.8% of Si, 1.5-1.7% of Mn, 1.4-1.6% of Cr, 0.3-0.5% of Ni, 0.4-0.6% of Mo, and 0.001-0.006% of B, and the rest of Fe. The thickness of the outer material is 10-20mm and the explosive pressure of mine is actuated on the outer material. The inner material is joined to an inner side of the outer material with a sealant and prevents the deformation of the outer material. The inner and outer materials are joined by riveting or bolting.
