The CV values of PL test between fans were calculated for every rock
type (Table 3). The highest CV is related to sample 10 (32.45%) while
samples 16, 1, 3 and 6 have lower CV values (2.23, 4.5, 5.14 and 5.52, respectively). The CV of the PL test results between different lithologies is
high in all parts of fans (from 71.79% to 80.86%) implying that different
rock types have various strengths. The percentage of reduction in the point load strength (the difference between maximum and minimum
divided by maximum, multiplied by 100) varies from 5.8 (sample 16)
to 56.65 (sample 10).
