Modelling of 3D domain boundaries using information from drill holes is a standard procedure in mineral exploration and mining. Manual logging can be difficult to exploit as the results may not comparable between due subjective nature geological logging. Exploration mining companies commonly collect geochemical or mineralogical data diamond core chips; however, manual interpretation multivariat...

Seismic image and velocity models were obtained from a newly conducted seismic survey around the Integrated Ocean Drilling Program (IODP) Japan Trench Fast Drilling Project (JFAST) drill site in the Japan Trench. Pre-stack depth migration (PSDM) analysis was applied to the multichannel seismic reflection data to produce an accurate depth seismic profile together with a P wave velocity model alo...

Dental tooth restorative procedures may weaken the structural integrity of the tooth, with the possibility of leading to fracture. In this study we present findings of coronal dentin strength after different techniques of surface modification. The fracture strength of dentin beams after superficial material removal with a fine diamond bur high speed drill hand piece, Er:YAG (2.94 μm, 8 J/cm(2))...

Introduction: The Bosumtwi Impact Crater in Ghana, Africa (6°32’N, 1°25’W) is a large complex crater. The crater is 10.5 km in diameter, with a central uplift 2 km in diameter. It is the source of the Ivory Coast Tektite field, found to the southwest of the crater over 200 km away. This study investigates the mineralogy, the petrology, and the geochemistry of drill core samples taken near the c...

Modern research in high energy physics depends on the ability to analyse massive volumes of data in short time. In this article, we report on DeLorean, which is a new system architecture for high-volume data processing in the domain of particle physics. DeLorean combines the simplicity and performance of relational database technology with the massive scalability of modern cloud execution platf...

Mountain geophysical prospecting operations play an important role in the entire petroleum exploration field. Geophysical drill-bit is main tool for mountain operations. Its hydraulic structure directly affects downhole flow field and then chip removal efficiency drilling of bit. At present, most scholars’ research focused on Poly Diamond Crystalline bit, roller etc., less, them study based cha...

Demand for mineral resources is increasing, necessitating exploitation of lower grade and more heterogeneous orebodies. The high variability inherent in such orebodies leads to an increase the cost, complexity environmental footprint associated with mining processing. Enhanced knowledge orebody characteristics thus vital companies optimize profitability. We present a pilot study investigate pre...

Understanding friction at diamond–rock interfaces is crucial to increase the energy efficiency of drilling operations. Harder rocks usually are more difficult drill; however, poor performance often observed for polycrystalline diamond compact (PDC) bits on soft calcite-containing rocks, such as limestone. Using macroscale tribometer experiments with a tip, we show that limestone rock (mostly ca...
