A high-performance coal mining machine cable is structurally characterized in that a power wire core, a control core group and filler are stranded to form a cable core, and the stranding pitch diameter ratio is not larger than 12; a reinforcing layer and a sheath layer are sequentially wrapped outside the cable core; the number of the power wire cores is three, and each power wire core is formed by sequentially wrapping a power wire core conductor with an insulating layer and an insulating shielding layer. The control core group is formed by twisting at least three same control cores and wrapping an inner sheath; the control core conductor is formed by stranding flexible tinned copper wires and bulletproof fiber wires at the same time. After the structure and the material are adopted, under the same condition, the special properties such as mineral oil resistance, flame retardant property, deflection resistance and the like are improved according to the actual environment, so that thecable has better environm
