Abstract
The invention discloses a mining cable of a flat structure. The mining cable comprises a plurality of wires. The wires are twisted and bundled into multiple sets. An isolating layer wraps each set of wires. Insulating layers wrap the isolating layers of the multiple sets of wires respectively. The multiple sets of wires are horizontally arrayed in parallel. An aluminum-polyethylene bonding layer wraps all the insulating layers of the multiple sets of wires. Vertical nylon fiber frameworks are arranged at the portions, between the adjacent sets of wires, in the aluminum-polyethylene bonding layer. High-temperature-resistant filaments are wound around the outer surfaces of the nylon fiber frameworks. A ceramic silicone rubber flame-retardant layer, a medal shielding layer, a tear-resistant layer and a fluoroplastic protective sleeve layer sequentially wrap the aluminum-polyethylene bonding layer, wherein the tear-resistant layer is formed by weaving polyester silks. The metal shielding layer is filled with magnesium oxide powder, and steel ropes are arranged in the magnesium oxide powder. The mining cable is simple in structure; the frameworks are added to the mining cable of the flat structure, and therefore pressure resistance of the whole cable is improved, practicability is higher, and meanwhile flame retardance and high temperature resistance are high.
