The invention provides a risk monitoring method and device for a coal pillar dam body and a coal pillar dam body monitoring system. The method comprises the following steps: constructing a target model according to a three-dimensional point cloud image; acquiring a first target signal and determining a first target position according to the first target signal; obtaining a second target signal, determining a first target range according to the first target position and the second target signal, and updating the target model according to the first target position and the first target range; acquiring a third target signal, and determining a second target position according to the third target signal; determining a target pressure according to the second target position, and updating a target model according to the second target position and the target pressure; when the first target range is larger than the first threshold value and/or the target pressure intensity is larger than the second threshold value, al
