Based on the test of rock mass mechanics, the rock mass of Shirengou Iron Mine was classified by RMR method, and then, the parameters of rock mass mechanics were estimated by Hoek-Brown.
From all the above figures it is clear that more or less curvilinear decline in the rock load height (RLH) with RMR is seen.
Therefore, the accumulation of FID with positive and negative irradiation offset can suppress strong single quantum signals in RMR experiments.
