The drill bits used in the mining industry have different sizes allowing to obtain a drill core from 20 to 165 mm in diameter (Hartley 1994). The most common drill bits are listed in the Table 4.2. The most practical and commonly used in the mining geology applications are drill bits of NQ, HQ and PQ size.The polygonal (or nearest-neighbor) technique assigns the geologic attribute to points or blocks in the three-dimensional space according to a fixed rule; for example, each block is assigned the geologic attribute from the drill hole data that is closest to its centroid (Stone and Dunn 1996). It is similar to a geologist drawing the interpreted ...
The most common tool used in modern geosteering is the gamma tool. It is robust, cheap, and provides valuable information about the lithology of where you’re drilling. Naturally occurring gamma radiation emitted by the rocks surrounding the tool are detected by the tool, and the data is transmitted to surface via mud pulse telemetry.
