Disclosed is an environmentally-friendly training hand grenade and a method of manufacturing the same. The training hand grenade is advantageous in that it is not necessary to recover fragments, generated by the explosion of the training hand grenade after use, because a bomb body of the training hand grenade is made of naturally degradable mineral matters, such as barite, tungsten, silica, and yellow earth, thereby many soldiers may be trained for a relatively short time using the training hand grenade. Furthermore, the training hand grenade is made of environmentally-friendly materials, and thus, its use is conducted without causing pollution. In addition, the training hand grenade is made of the mineral matters, thereby ensuring high explosiveness and explosive sound effect when the training hand grenade is exploded, and preventing soldiers from being injured by the fragments in use. Moreover, the training hand grenade has almost the same weight as a hand grenade for live battle, leading to the simplification of the manufacture of the training hand-grenade to improve productivity. Accordingly, the manufacturing costs of the training hand grenade are largely reduced, which contributes to reducing prices of the training hand grenade.

What is claimed is: 1. An environmentally-friendly training hand grenade, comprising: a fuse body made of a biodegradable resin; and a bomb body screwed over the fuse body at an upper part thereof, having an integrated solid structure which has no charging space therein, and made of a mixture of naturally degradable mineral matters including barite, tungsten, silica, and yellow earth. 2. The environmentally-friendly training hand grenade as set forth in claim 1, wherein the bomb body comprises 80 to 90 wt % of barite, 5 to 10 wt % of tungsten, 0.1 to 0.5 wt % of silica, and 2 to 3 wt % of yellow earth. 3. A method of manufacturing an environmentally-friendly training hand grenade, provided with a bomb body and a fuse body, comprising: a raw material feeding step of feeding raw materials, including barite, tungsten, silica, and yellow earth, into an agitator to manufacture the bomb body; an agitating step of agitating the raw materials to uniformly mix the raw materials with each other; a molding step of adding an adhesive and water to the mixed raw materials, and molding the resulting mixture to form the bomb body and to simultaneously form an internally-threaded part at a center part of an upper part of the bomb body; a heat-treating step of heat-treating the bomb body to improve strength of the bomb body; a fuse body assembly step of screwing the internally-threaded part of the bomb body, having the strength improved through the heat-treating step, over an externally-threaded part of the fuse body made of a biodegradable resin to manufacture the training hand grenade; and a packing step of packing the training hand grenade.
