Abstract

The invention discloses a roadway surrounding rock stability combined testing device and a testing method, The roadway surrounding rock stability combined testing device comprises a control host, a borehole observation instrument, a loosening circle test instrument and a geology radar test instrument. The borehole observation instrument is used for testing the surrounding rock crack developing degree on the inner wall of the borehole bored on the side of the roadway or on the top plate of the roadway; the loosening cycle tester is used for performing the loosening cycle test on the surrounding rock in the circumference of the borehole; and the geology radar test instrument is used for testing the stability of the surrounding rocks on the top or the side of the roadway under the coal mine. The testing method comprises steps of 1 hole boring, 2 a surrounding rock stability combined test including a single hole test and a roadway integral geography radar detection, 3 comprehensive analysis and determination, 4 surrounding rock stability combined test of a next roadway segment, 5 multiple times of repeating step 4, and then the surrounding rock stability under the coal mine combined test process is finished. The roadway surrounding rock stability combined testing device and the testing method disclosed by the invention realizes convenience and accurate test results, and solves the problems in the prior art the accuracy is low and the accuracy of testing the stability of the roadway surrounding rock is hard by using a single monitoring mean.

Description

technical field [0001] The invention belongs to the technical field of geotechnical and mining engineering, and in particular relates to a combined testing device and testing method for the stability of roadway surrounding rock. Background technique [0002] In order to ensure the stability of the roadway under the coal mine, the surrounding rock of the roadway will be tested with detection technology before the design of the roadway support. The stability of the surrounding rock is used for roadway support design. Nowadays, there are many technical means for monitoring mine surrounding rocks, such as acoustic emission, optical fiber, and resistance strain gauge, etc., but they all focus on a certain technical means. Due to the diversity and complexity of coal and rock formations, the large spatial dimensions In the process of on-site monitoring, there are many interferences from external factors, and many monitoring results are distorted. It can be seen that a single monit...
