The Mining Process – Waihi Gold
2022-1-26 · The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Typical Blasting Methods for Structural Engineering
Blasting technology is an essential part of the construction process to perform structural engineering activities. Blasting is the process of cracking rock material by using a small amount of explosive substance so that the rock is destroyed into several pieces. In the past, black powder and dynamite were used for the explosive process.
