The width of the cylinder is a critical dimension for the determination of draw point spacing in relation with block caving mine design. The overall control of the draw column width is the mobility or lack of resistance to flow motion of the material being drawn.

In block caving mines, the gravity flow of caved (broken) ore controls the amount of valuable material recovered and the extent to which it is diluted by caved waste rock. In addition, it also dictates the spacing, and thus the number of drawpoint required, which has a large impact on capital ...

This is a return statement, which only appears inside def-blocks. Remember how the input() function returns a string value that the player typed in? The chooseCave() function will also return a value. Line 17 returns the string that is stored in cave, either '1' or '2'.. Once the return statement executes, the program execution jumps immediately out of the def-block.

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
