Test Method and Application of Broken Rock Zone of Roadway Surrounding Rock by Borehole Imaging

Abstract:

It is of great significance to select the reasonable support pattern and support parameters for accurately determining the magnitude of the broken rock zone of roadway. At present, the test methods of the broken rock zone of the roadway surrounding rock all have stated disfigurements and deficiency. The borehole imaging method has advantages: simple operation and the test results being intuitive and reliable. The test results and analysis of the broken rock zone of rail crossheading in 3down 109 coal face of Luxi Coal Mine show that the test results consistent well with the actual situation and they have practical reference value for the test and application of the broken rock zone of the roadway surrounding rock.
