This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploration with impregnated diamond drill bits is the key operation in the mining and mineral industry. Demand for deep exploration drilling is significantly increased recently due to the rapid depletion of near surface mineral deposits globally. One of the main problems encountered during drilling operation is to infer bit wear in great depth remotely as the optimal performance of the drill still relies heavily on operator experience. This paper aims to assess the feasibility of Acoustic Emission (AE) monitoring of the impregnated diamond drilling process and establish relationships between AE and diamond drill bit wear, as well as establishing AE relationships with various drilling parameters. A full drill rig, Echidna drill apparatus, simulating field exploration diamond drilling on a small scale, were used to monitor AE during rock bit interaction. AE sensors were attached to both the drill and the rock to record acoustics being emitted during drilling. Initial tests on the Echidna drill involved stepping down the depth of cut from 130μm to 0μm, whilst keeping revolutions per meter (RPM) constant. Secondary tests performed on the Echidna drill involved accelerating the wear rate of the drill bit via two different types of wear in highly abrasive rock. Based on step test results, a series of linear relationships were developed which are capable of estimating the depth of cut, force by simply using time spectrum of the AE signals. Wear tests also showed that AE amplitudes start to trend down over the time of accelerated wear.

This book was released on 2014 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems encountered in impregnated diamond core drilling operations for deep mineral explorations is to remotely infer bit wear state and to drill with optimal performance at great depth. Currently the optimal drilling performance relies heavily on operator experience. This paper aims to assess the feasibility of acoustic emission (AE) monitoring of the impregnated diamond drilling process and to establish relations between AE signals and diamond drill bit wear to improve overall drilling performance. AE relations with various drilling parameters have also been investigated to understand signal characteristics in relation to operational parameters. Echidna drill apparatus that simulates field exploration diamond drilling on a small scale is used to monitor AE during rock bit interaction. AE sensors were attached to both the drill and the rock in question to record acoustic signals being emitted whilst drilling. Two different tests viz. 'step tests' and 'wear tests' were carried out. Step tests on the Echidna drill include stepping down the depth of cut from 130μm to 0μm, while cutting speed is constant. Secondly, wear tests performed on the Echidna drill, involves accelerating the wear rate of the drill bit via two different types of tests, both in highly abrasive rock. Based on the step test results, a series of linear relations were developed. These relations are capable of estimating the depth of cut, weight on the bit (WOB) and torque on the bit (TOB) by simply using time spectrum of the AE signals. Wear tests also showed that AE amplitudes start to trend down over the time of accelerated wear.

This book was released on 2016-11-18 with total page 1371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rock Mechanics and Rock Engineering: From the Past to the Future contains the contributions presented at EUROCK2016, the 2016 International Symposium of the International Society for Rock Mechanics (ISRM 2016, Ürgüp, Cappadocia Region, Turkey, 29-31 August 2016). The contributions cover almost all aspects of rock mechanics and rock engineering from theories to engineering practices, emphasizing the future direction of rock engineering technologies. The 204 accepted papers and eight keynote papers, are grouped into several main sections: - Fundamental rock mechanics - Rock properties and experimental rock mechanics - Analytical and numerical methods in rock engineering - Stability of slopes in civil and mining engineering - Design methodologies and analysis - Rock dynamics, rock mechanics and rock engineering at historical sites and monuments - Underground excavations in civil and mining engineering - Coupled processes in rock mass for underground storage and waste disposal - Rock mass characterization - Petroleum geomechanics - Carbon dioxide sequestration - Instrumentation-monitoring in rock engineering and back analysis - Risk management, and - the 2016 Rocha Medal Lecture and the 2016 Franklin Lecture Rock Mechanics and Rock Engineering: From the Past to the Future will be of interest to researchers and professionals involved in the various branches of rock mechanics and rock engineering. EUROCK 2016, organized by the Turkish National Society for Rock Mechanics, is a continuation of the successful series of ISRM symposia in Europe, which began in 1992 in Chester, UK.

Available in PDF, EPUB and Kindle. Book excerpt: The drilling response of impregnated diamond (ID) bits is controlled by processes involved in the rock fragmentation, and also the wear processes that continuously change the bearing surface of diamonds and bonding matrix. Due to the co-existence of these two processes both affecting the overall drilling response but differently based on drilling conditions (operating parameters, bit, rock and drilling fluid), the response of ID bits has been found inconsistent and difficult to interpret. In this paper, wear mechanisms of impregnated diamond bits are studied using a series of precise state of the art cutting and drilling experiments conducted with impregnated diamond bits and segments. The wear responses are decomposed into three phases of polishing, fracturing and sharpening, and the response in each phase is analyzed using interface laws in terms of depth of cut, and the extents of frictional contacts. The variation of the response at various operating parameters (weight on bit and depth of cut) are obtained and conceptual models characterizing the drilling response under both weight-on-bit and depth of cut conditions are presented.
