Buried cable trough for open-pit mine

A buried cable trough for an open-pit mine relates to the technical field of open-pit mining, and comprises a cable trough, a trapezoidal broken stone buffer layer and a broken stone layer, the cablepenetrates through the cable groove, and the opening of the cable groove faces the two sides. The rubble layer wraps the periphery of the cable trough to form an arched slope surface; the cable bridgeis simple to manufacture, saves steel materials, and eliminates a plurality of difficulties that the cable bridge is inconvenient to use. 一种露天矿用地埋式电缆槽，涉及露天矿山开采技术领域，包括电缆槽、梯形碎石缓冲层、碎石层；所述电缆线从电缆槽中穿过，电缆槽的开口朝向在两侧；碎石层包裹在电缆槽的周围形成拱形坡面；制作简单节省钢材，同时消除了电缆桥架使用不方便的诸多困难。
