| Abstract: | A mathematical model for calculating the radiation intensity of natural gamma ray penetrating through the coal seam and the canopy of hydraulic support was set up. In this model the function relationship between the coal seam and the radiation intensity of gamma ray passing through the coal seam was considered. The influence of the canopy of hydraulic support upon the measuring results of the thickness of coal seam was also analyzed. It comes to the conclusion that the difference of the radiation intensity of gamma ray between with and without considering the canopy of hydraulic support is 13.6%. The mathematical model was verified by the experimental results of measuring the thickness of coal seam in Tangshan Coal Mine. |
