The Research Of γ-ray Detecting And It's Application To The Jigging Coal Running

In this thesis, a dynamic way to density detecting of the jigging coal bed based on the theory of γ-ray in density detecting is proposed.Based on the research into the theory of jigging delamination,the mechanism of the y-ray in material density detecting and the theory of γ-ray in counting numbers, the design project of the detecting system of the coal bed density is confirmed; in the laboratory, a series of relative experiments are made to obtain the gating voltage and relative parameters of the discriminating ware in the detecting system. The laboratorial test of the y-ray detecting system shows: γ-ray detection can get the true density of the jigging bed layer and reflect the state of the jigging bed layer correctly, both in a considerable level.As the y-ray detecting system running in DongPang Coal Mine in XingTai, real-time data is collected and analyzed, a conclusion is reached: the way of γ-ray in detecting the densityof jigging bed layer has considerable precision. The density values detected in different bed layer schlep abundance information, which can provide evidence to the optimizingcontrol of the coal-delivering, wind, water and eduction.
