  "definition": "The process of establishing a true vertical line down a mine shaft using one or more weighted wires, known as plumb lines. This surveying technique transfers surface coordinates to the underground workings, providing a reference for aligning tunnels, drifts, and raises. The accuracy of the alignment depends on factors like the depth of the shaft, air currents, and the weight of the plummets used.",
