How to calculate stripping ratio? - ResearchGate

For instance: If the thickness waste rock (overburden) is 100m and the thickness of coal is 50m then stripping ratio would be 2:1. That means one m3 (cubic meter) of coal would need mining two m3 ...

Rolling (metalworking) - Wikipedia

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is ...

For the Case 2, a machining path interval planning algorithm is established based on the MRP model. Set the material removal profile at the nth grinding point on the ith path is E in, the maximum grinding depth of cut is h max which satisfies h max > h s.As shown in Fig. 4, E in overlaps with the material removal profile E (i+1) n at the nth grinding point on the (i+1)th path.
