Point column recovery method based on permanent point column reinforcement and permanent point column reinforcement structure

The invention discloses a permanent point column reinforcement-based point column stoping method and a permanent point column reinforcement structure, and the method comprises the steps: carrying out the stability analysis of a point column stoping region, selecting out a permanent point column needing to be reinforced, and obtaining the dominant structural plane occurrence and properties of the permanent point column through the engineering geological survey and exploration analysis; carrying out primary reinforcement on the permanent point column according to the occurrence and the property of the dominant structural plane of the permanent point column, and arranging a plurality of stress meters in the circumferential direction of the permanent point column in the primary reinforcement process; the point columns in the reinforced point column recovery area are recovered, the stress evolution law of the permanent point columns is monitored through a stress meter, and if it is monitored that the stress value
