Based on the principle of the function of mine clearance by the way of blasting tube, the 8.2 kg solid-state FAE(fuel air explosive) mine clearance device was designed. By changing the initial explosive position and the method of setting up, in the multiple field near ground explosion tests, the stress tests were conducted by adopting reflection pressure sensor to test forward and lateral pressure from different explosive locations, at the same time a certain type of anti-infantry mines in the corresponding burst position of the forward line pressure sensor was set, and the explosive parameters in different location′s explosive field and the scope of anti-infantry′s mines clearance was obtained. Results show that the clearance range of the horizontal charge was significantly larger than that of the vertical charge, and the optimal blast height was about 0.60 m. Moreover, the acting time curve of the positive pressure zone of the explosion field is of “V” type, and the acting range of the product is up to 63 times of the charging radius, which has obvious advantages over the acting time of equivalent TNT. The mine clearance range of this device is about 1.8~3.85 times of the current mine clearance range of blasting tube blasting, the forward reliable mine clearance range can be 77 times of the charging radius, and the side can be 69 times. Since the positive pressure action time of the explosive zone is significantly longer, so it is beneficial to the clearance of all kinds of mines, and it is a potentially efficient humanitarian mine-clearing charge.
