Problems solved by technology

At present, the collected data is mainly recorded and input manually. The problems in this method are: due to the large amount of collected data, the workload of on-site recording and input to the computer is heavy; on the other hand, in the process of recording and input It is easy to artificially cause omissions, mistakes and input errors

Abstract

The invention discloses a monitoring method for the movement of subterranean strata, the method includes: (1) the deforming value of different measuring section from the two front-back directions along the A and B direction of the every hole is gathered by the clinometer, and the deforming value is recorded by the secondary data collector; (2) the testing data gathered in the step (1) is processed by the data communication program to realize further data conversion processing that includes checking the detecting value is error or not; (3) the monitoring data is gathered periodically following the step (1) and step (2), the subterranean displacement monitoring curve is produced according to the data processing result, the damage characteristic and type are determined according to the curve, and the position of glading plane or the deformation boundary are determined. The on-site monitoring data can be gathered intelligently, converted, stored and recorded, and the slope stability of the opencut coal mine can be monitored by monitoring and analyzing periodically.

Description

technical field [0001] The invention relates to a method for monitoring underground rock movement, in particular to a monitoring method for underground rock movement used for slope stability monitoring in open-pit coal mines. Background technique [0002] Underground rock movement monitoring in open-pit coal mines is an important part of slope stability research. Underground rock movement monitoring is to measure the displacement, displacement speed and direction of the underground rock mass relative to the stable stratum through instruments, so as to determine the slip surface and deformation change law of the moving rock mass. The existing method for monitoring underground rock movement is realized by drilling holes in engineering geological exploration. The drilling holes in engineering geological exploration are used to establish underground displacement monitoring holes, and monitoring pipes are installed in the monitoring holes. Boreholes used for underground rock mas...
