Many natural pores, cracks, and bedding are unevenly distributed in the coal body. 1,2 The heterogeneity of the coal has a relatively large impact on the coal’s mechanical properties; even if the coal samples come from the same coal seam, they have different mechanical properties. 3,4 Most scholars ...

The two quantities are said to be in golden ratio if their ratio is equal to the ratio of their sum to the larger of the two quantities i.e. (a + b)/a = a/b, where a > b > 0.
