For measuring underground stope convergence device

摘要

The equipment works, so that mutual distance between profile underground chamber (16) is at least three measurement points, (1,2,3,4,5,6,7,8, (16) 0 be initially by the value of the exploration geodesic survey of three-dimensional measurement and the distance for the point for realizing this method (16) 1 to (16) 2 or to replace the stability of these distances be evaluation underground engineering (16) 3 and required for rebuilding this underground excavation (16) 4 of measure in. Label (11) of the measurement between measurement point in (1 to 9) progress laser range finder (10) of distance is located at a measurement point (1 to 9) and exploration is gradually located at other measurement points (1 to 9) to label (11). There are the labels (11) on laser range finder (11) (10) gradually to survey to set on other measures point (1 and 9) for underground chamber and at least one label on the wall (18) of equipment measurement point (1 to 0) as built in marking (11).
