The utility model discloses a mobile elastomer flexible cable for a coal mine, and the cable mainly consists of power line core conductors, insulating layers, a filling layer, a ground wire core conductor, a sheath, and insulating shielding layers. The sheath wraps three power line core conductors and one ground wire core conductor. The power line core conductors are wrapped by one insulating layer which is wrapped by one insulating shielding layer. The ground wire core conductor is wrapped by one insulating shielding layer. The filling layer is disposed between the three power line core conductors and one ground wire core conductor. The cable provided by the utility model is good in insulating performance, performance of resistance to high temperature, and fireproof performance. Meanwhile, the cable is resistant to aging, is resistant to acid and alkali, and is resistant to corrosion.
