Abstract

The invention discloses a mining overburden separated strata allometry test monitoring system based on the digital speckle technology and an analysis method. The system comprises an experiment terminal, a monitoring terminal, and a processing terminal, the experiment terminal comprises an experiment table and an experiment model, the monitoring terminal comprises a high-speed camera, an industrial camera, a support, a white light source, and a calibrated scale, and the processing terminal comprises image acquisition cards, computers, and mobile hard disks. According to the method, simulation tests of similar materials are monitored based on the digital speckle technology, the allometry theory is employed for the analysis and measurement of the mining overburden separated strata caused by mining, the change condition of speckle points on the surface of an object is shot with the combination of the white light digital speckle method, deformation information of the object surface is obtained via the tracking of the movement of the points, micron-grade monitoring precision can be realized, the problem of difficult artificial capture is better solved, the allometry theory is firstly introduced for analysis, and quantified research of the development process is realized.

Description

technical field [0001] The invention belongs to the technical field of mining safety monitoring, and relates to a new analysis method for the development process of the mining overburden detachment layer, in particular to a simulation experiment of the allometric growth similar material of the mining overburden detachment layer based on digital speckle technology analysis method. Background technique [0002] my country has a vast land and abundant resources, rich and diverse resources, among which energy resources are characterized by abundant coal resources and relatively few oil and natural gas resources. With the rapid development of the economy, people's demand for energy is increasing. Although the development of science and technology has produced some new energy sources, the demand for coal resources still occupies a dominant position. The high demand has led to overexploitation of coal, which has led to large areas of subsidence. my country's subsidence area has r...
