Similarity experiment rock deformation monitoring data acquisition method, system and equipment

Abstract

The invention relates to a similar experiment rock deformation monitoring data acquisition method, system and equipment, belongs to the technical field of open-pit-to-underground mining, and aims at enabling a rock deformation curve to be more obvious by uniformly smearing gypsum on a to-be-monitored surface and facilitating researchers to accurately identify rock deformation so as to observe andanalyze a deformation phenomenon. By arranging the wire mesh structure used for fixing the signal lines connected with the strain gauges, the strain gauges are arranged more stably and are not prone to being interfered by the signal lines, and experiment errors are reduced. By setting the attaching sequence of the strain gauges and the moving sequence of the wire mesh, the strain gauges can be attached more smoothly. The firecrackers are used for simulating the vibration effect of underground blasting on the open-air stepped stope, and the method, system and equipment can be used for researching the influence rule of underground blasting on the stability of the open-air stepped stope. The wire mesh used for fixing the signal line connected with the strain gauge has good repeatability and can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of open pit-to-underground mining, and in particular relates to a method, system and equipment for obtaining monitoring data of rock mass deformation in a similar experiment. Background technique [0002] With the continuous development of my country's mining industry and the continuous improvement of mining technology, more and more open-pit mines have begun to turn to underground mining, thereby improving the utilization efficiency of mineral resources. In the underground mining project of the open-pit to underground mine, since the upper part (ground surface) is the stepped stope left after the open-pit mining, and during the underground mining process, the open-pit stepped stope is often still in use and shoulders part of the Production tasks, such as transport tasks. Therefore, how to ensure the stability of the surface stepped stope is a crucial point in the process of converting from open pit to unde...

Problems solved by technology

[0004] However, this method has the following problems: the deformation of the rock mass is judged by the naked eye through the pictures taken by the camera. Since the similar model rock mass is mostly made of sand, barite, cement and other materials, its surface is relatively rough and the color is dull, so that in the When observing deformation, some subtle deformation curves are often missed, such as sinking curves
