The present disclosure discloses a hoisting cable with small diameter, high strength, and high flexibility, including an inner conductive core, an insulating layer, an outer conductive wire layer, a tensile layer, and an outer protective layer. The insulating layer is located at an outer side of the inner conductive core and provides insulation between the inner and outer conductors; the outer conductive wire layer is located at an outer side of the insulating layer; the tensile layer is located at an outer side of the outer conductive wire layer; and the outer protective layer is located at an outer side of the tensile layer. The high tensile strength can ensure the safety of hoisting operations, and the small diameter, small bend radius, and high flexibility can ensure the minimization design and the large rope capacity of a winch.

Manufacturing method of a hoisting cable with small diameter, high strength, and high flexibility

A method for heating oil shale underground in situ. Shale oil and fuel gas can be obtained from an underground oil shale seam in situ, and the fuel gas can also be obtained from an underground coal seam in situ. Wells are drilled downwardly reaching an operation region of an underground oil shale ore bed. Electricity for partial discharge of the ore bed is conducted into electrodes, and a plasma channel is formed in the ore bed and subjected to breakdown by the electricity; after the resistance of each of two electrode regions is lowered, the two electrodes are used for conducting currents into the plasma channel in the oil shale ore bed; the oil shale ore bed is heated under the resistance heating function of the plasma channel; and released heat is used for realizing thermal cracking and gasification of fixed organic carbon in the oil shale ore bed.
