The invention provides a passive spring-damping negative stiffness damper for inhaul cable vibration mitigation. The passive spring-damping negative stiffness damper for inhaul cable vibration mitigation comprises two negative stiffness parts based on precompression springs, a connecting arm, an oil damper part and an outer frame. The two negative stiffness parts based on the precompression springs are symmetrically located on the two sides of the connecting arm and hinged to the two ends of the connecting arm. The connecting arm is fixedly connected with the upper end of a piston rod of the oil damper part. The bottom end of an oil damper is fixedly connected with the bottom end of the outer frame. The passive spring-damping negative stiffness damper for inhaul cable vibration mitigation can achieve negative stiffness under passive control, thereby remarkably improving the control effect of an original oil damper over inhaul cable vibration; different negative stiffness and control effects can be achieved by adjusting the stiffens coefficient, the original length and the compression amount of the precompression springs.
