Available in PDF, EPUB and Kindle. Book excerpt: "As the mining industry continues to embrace technology to become more efficient and more environmentally conscious, automated solutions and processes will become more common. This is true for all types of mining independent of commodity or type of operation (surface or underground). Due to the specifics of its application a production drill used in surface mining is an attractive use case for automation – either full or of operator assist variety.The full operational cycle of a production drill rig is explored in detail; challenges and constraints regarding the implementation of automation are identified. The operational impacts of utilizing an automated production drill rig are commented upon.The research details the design, development and testing of a novel and advanced drill control system that incorporates advanced exceptions handling concepts thereby allowing the solution to be more appropriate for use during long periods of unsupervised drilling which represents the majority of a production drill’s operational cycle. Testing of the developed drill control system at a working mine site on a production drill was conducting and the results are presented and discussed. In addition, the influence of drill bit design on drill performance (and control) is explored and the influence of bit wear is commented upon.A drill propel and positioning solution that incorporates HPGPS sensor information and crawler track motor speed sensor information is proposed. Required positioning accuracy is defined. The propel and positioning solution was tested at a working mine site on a production drill and the results are presented and discussed. The requirements of an automatic levelling system are defined, and an improved solution is proposed.The research concludes with a proposal for a new intelligent drilling concept that includes better incorporation of the mine model and mine planning tools, automatic blast pattern generation, and on-the-fly pattern adjustment based upon monitoring-while-drilling signals. An overall, conceptual integration of the various proposed solutions is also presented"--

Book Synopsis Comparative Modeling by : Daniel Joseph Lucifora

Book excerpt: Most rotary blasthole drills used in the mining industry today are equipped with automatic control systems. However, few, if any, implement closed-loop feedback control of the drilling process itself. This thesis investigates the potential for such control on a large rotary electric blasthole drill. The control strategy examined is Proportional-Integral-Velocity (PIV) control. The drill was successfully equipped with a data logger, and a comprehensive set of drilling data was gathered at an open pit taconite mine in northern Minnesota. This data set was used to model the dynamics of both the feed and rotary actuators. A drilling process software simulator, based on hydraulic blasthole drill data originally developed in previous work [Aboujaoude 1991], was successfully replicated in Simulink, and thoroughly documented, overcoming a major shortcoming in Aboujaoude's work which provided incomplete information on the simulator implementation. The control strategy from the previous work was successfully integrated with the new process simulator, and its performance validated by comparison with the results presented in the previous work. The drilling process simulator was then modified by replacing the actuator dynamics with the models identified for the electric drill. The modified simulator was validated, and the behaviour of the system with the new actuator models while under feedback control was observed. The controller gains were re-tuned to achieve acceptable drilling performance with the new actuator models. This resulted in a prototype controller ready for field testing on the large rotary electric blasthole drill. In addition, this thesis has produced a fully documented drilling process simulator, suitable as a platform for future research.

Book Synopsis Investigation of Vibration Related Signals for Monitoring of Large Open-pit Rotary Electric Blasthole Drills by : Edward A. Branscombe
Download or read book Investigation of Vibration Related Signals for Monitoring of Large Open-pit Rotary Electric Blasthole Drills written by Edward A. Branscombe and published by . This book was released on 2010 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigated the monitoring and analysis of signals related to the vibration of large rotary blasthole drills. The research focused on a machine with electric drilling actuators: such machines are used as primary production equipment in the drill-and-blast cycle of the surface (open-pit) mining process. The performance of such machines is limited by the onset of severe vibrations, which can arise due to the interaction of geology, bit, drill string, machine structure, and control settings. Experimental data for the thesis were obtained during field periods at an iron ore mine in Minnesota's Mesabi Iron Range. The data acquisition and signal analysis techniques which were utilized are presented, including smoothing of signals and calculated variables such as specific energy. Ambient vibration sources and vibration aliasing issues are investigated. Results from analyzing structural response tests indicate that, as expected, the natural frequency of the drill mast decreases with increasing bit depth - although the mounting position of accelerometers distorts this trend. The pull down force (weight on bit) is shown to have no appreciable impact on the mast's natural frequency, nor on the mast's damping ratio. A strong relationship between rotary speed and the dominant vibration frequency peaks at 3x and 6x rotary speed is demonstrated, and a physical explanation of the 6x vibration peak is postulated. The rotary motor current is shown to consistently exhibit frequency peaks at 3x and 6x rotation speed, indicating that this variable is a good candidate for use either as a substitute for accelerometer feedback, or as an auxiliary signal to detect down-the-hole vibration when it is not manifested by the mast mounted accelerometers. System identification is used to demonstrate that the dynamic relationship between vibration and rotary current, while it can be modeled locally, varies with depth and geology and hence is essentially a time-varying process. This results in the amplitude of rotary current not being usable as a proxy for vibration amplitude. Nonetheless, it is demonstrated that the root-mean-square (RMS) of the low frequency current oscillations, in a nonlinear combination with the RMS of the current signal as a whole, may be able to serve as a proxy for the RMS of the vibration signal.
