Problems solved by technology

[0003] The purpose of the present invention is to provide a method that can more accurately measure roof structure changes and separation layers, so as to solve the problem that the existing technology is unclear about the reasons for the roof deformation and cannot accurately determine the deformation of the rock itself and the structure change in the total deformation. Proportion, and then can not take more effective measures to prevent and deal with the problem

Embodiment Construction

[0010] see figure 1 , the implementation process of the present invention is: set two boreholes with the same diameter and depth in a certain section 1 of the mine roadway, one of which is a deep displacement measurement borehole 2 for measuring the total displacement of rock formations at different depths; the other is Peep hole 3 is used to observe changes in rock structure and abscission values.

[0011] Through an instrument (peeping instrument) 4 that can observe the rock formation structure in the borehole, the peeping borehole 3 is observed. The observation content includes rock bedding, joints, crack development positions, etc., and the layer is determined by the scale on the installation rod 5 The positions of bedding, joints, and fissures in the borehole are recorded by the receiver 8; the position is observed by the scale 6 through the rod installed on the peeping instrument 4, and the original dimensions of the bedding, joints, and fissures are recorded. Simultane...

Abstract

This is a method to detect strata shifting for bord. Two holes of the same diameter and height are drilled along any fracture surface of the bord, one is for detecting strata shifting and the other is for viewing of structure transform of strata to figure out the ratio of structure transform to total shifting.

Description

technical field [0001] The invention relates to a method for on-site measurement of roof structure change and separation layer in underground geotechnical engineering, which is used for on-site measurement of roof structure change and separation layer in underground geotechnical engineering departments such as mines, construction, electric power, water conservancy, railway, military industry and the like. Background technique [0002] The present invention is aimed at the fact that in the current geotechnical engineering construction, the cause of the deformation of the roof is not clear, and the proportion of the deformation of the rock itself and the structural change in the total deformation of the rock layer cannot be determined more accurately, and then more effective measures cannot be taken to prevent and deal with it. Contents of the invention [0003] The purpose of the present invention is to provide a method that can more accurately measure roof structure changes...
