OEM Small-Sized Cheap Crawler-Mounted Rock Core Drilling Rig Machine for Mineral Exploration Purpose
What is Exploration Drilling?
The purpose of exploration drilling is to obtain a continuous sample of the bedrock. The drill core sample is logged to define rock types, and portions are often sampled and chemically analyzed to help further characterize rock types and to look for the presence of economic minerals.
Each drill hole can encounter various types and thicknesses of soils, glacial till and rock types.
Our types of Shitan drilling rigs can be applied in the related field of mineral exploration, considering the differences of rock & soil conditions.
