1) Short holes have advantages like following irregular contacts but have disadvantages like low productivity and high costs. Long holes have high productivity but are limited to regular deposits. 2) Common mining methods include overhand stoping, breast stoping, cut-and-fill stoping, and shrinkage stoping. 3) Drilling methods include jumbo drilling, handheld drills, and long hole down-the-hole hammer drilling. Drilling parameters like depth, diameter, and speed depend on the specific method and machine used.
