摘要（英）：

The invention relates to a special mine illumination lamp. The special mine illumination lamp is provided with an upper cover, a body, an explosion-proof cavity, an explosion-proof pad, a glass cover and a body surface cover. The body is connected with the body surface cover through bolts. The upper cover is connected with the body through bolts. The explosion-proof cavity is formed by a gap between the body and the upper cover. A horizontal threaded hole is formed in the side face of the upper cover. A boss is arranged in the body. The explosion-proof pad is fixed to the boss through bolts. A cable hole is formed in the bottom of the body. A cable penetrates the cable hole and is connected with a light source. The explosion-proof cavity is formed between adjacent threaded holes of the body surface cover. The edge of the explosion-proof pad and the edge of the glass cover are connected in a fastened manner through the bolts between the body and the body surface cover. The special mine illumination lamp has the beneficial effects of being good in explosion-proof performance, simple in structure and convenient to disassemble and assemble.
