Non-Gaussian Hybrid Transfer Functions: Memorizing Mine Survivability Calculations

Table 1

Common rocks found in typical mines in relation to hardness or softness.

Nonlinear mapping	Mica	Coal	Granite	Feldspar	Quartz	Mineral
Softness	0.70	0.80	0.83	0.86	0.875	0.90
Hardness	2	3	5	6	7	9
Distance	750 m	470 m	390 m	315 m	278 m	78 m

Data was collected from Wang Xing village, located in Xinzhen City, Henan Province, China.
The table identifies 6 common rocks found in mines in relation to hardness or softness of each rock.
