Mining Haul Truck Pose Estimation and Load Profiling Using Stereo Vision
Mining Haul Truck Pose Estimation and Load Profiling Using Stereo Vision by James Robert Borthwick B.Sc., The University of British Columbia, 2003 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in The Faculty of Graduate Studies (Electrical and Computer Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) August 2009 c James Robert Borthwick 2009 ! Abstract Earthmoving at surface mines centers around very large excavators (mining shovels) that remove material from the earth and place it into haul trucks. During this loading process, the truck may be inadvertently loaded in a manner that injures the truck driver, or that results in an asymmetrically loaded or overloaded truck. This thesis presents two systems which aim to assist with haul truck loading: 1) a stereo-vision based system that determines a haul truck’s pose relative to the shovel housing as part of an operator loading assistance system, and 2) a system that can determine a haul truck’s load volume and distribution as the truck is being loaded. The haul truck pose estimation system is significant in that it is the first six-degrees of freedom truck pose estimation system that is sufficiently fast and accurate to be applicable in an industrial mine setting. Likewise, it is the first time that a system capable of determining a haul truck’s volume as it is being loaded has been described. To achieve this, a fast, resolution independent nearest neighbour search is presented and used within Iterative Closest Point (ICP) for point cloud registration. It also shown, for the first time, to the best of our knowledge, the possibility of using the Perspective-n-Point (PnP) pose estimation technique to estimate the pose a range-sensor derived point cloud model, and to use the same technique to verify the pose given by ICP. -

However, some pits are quite deep – about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd Open pit mining results in two waste streams: waste rock which contains no economic quantity of minerals but which must be removed to gain access to the orebody, and tailings which are the result of a mineral separation process in the concentrator or processing plant. The mining rate includes the mining of both waste and ore. Open pit mining is non‐selective – all high and low grade zones of the orebody are mined The significant design issues of an open pit mine are: location of haul roads, equipment – size of trucks and fleet, pit slope angle and stability, control of water PwC Mining Methods 5 Bagdad Pit, Arizona – looking west Porphyry copper 170,000 tpd 9,200 ft 5,800 ft pit 828 Mt sulfide and oxide reserves: 0.28% Cu, 0.022% Mo (2007 10K filing) Copper and Molybdenum concentrates Pressure leach facility for concentrate, SX/EW leach plant for oxides PwC Mining Methods 6 Notes: Bagdad Pit Arizona – looking west First claims staked in 1882. -

Mechanical and Electrical Design of Power Excavators (Paper & Discussion)
DESIGN OF POWER EXCAVATORS. 41 PAPER MECHANICAL AND ELECTRICAL DESIGN OF POWER EXCAVATORS. By T. W. Fairhurst. JUSTIFICATION FOR USE OF POWER EXCAVATORS. The power excavator owes its original existence, and sub- sequent widespread use, to the fairly obvious fact that the great and small earth and mineral moving projects of the world could never be carried out economically by manual la- bour, even if such labour were available in ample quantity. Irrigation and reclamation works, construction of railways, docks, harbours, etc., open-strip mineral mining, quarry work- ing, as well as large and small contracting works have been rendered possible to their present extent only by the power excavator. HISTORY OF POWER EXCAVATION. The detailed history of power excavators is material for several volumes, and it is, therefore proposed to refer to this history only in such a way as to give a sound general impres- sion of the course of development. Prior to 1836 a very crude single steam engined digger was produced by one Otis, of Philadelphia, U.S.A., for work on the first American railroad construction between Albany and Schenectady, in N.Y. State. This . machine, although. crude. clumsy and slow, quite justified its existence and did considerable excavation at much lower cost than equivalent hand labour. Between this time and about 1875 several steam exca- vators were built in America, and, it is believed, one or two were tried in Europe with very indifferent success. The American-built machines, about twelve in number, all did fair work on the Erie Canal and other jobs, but, owing to the high-handed attitude of the manufacturers, few customers were obtained or retained. -

NOTHING HEREIN IS TO BE REGARDED AS INDICATING APPROVAL OR DISAPPROVAL OF ANY SPECIFIC PRODUCT OR PRACTICE. 2 FOREWORD This manual is designed primarily as a text to be used in the teaching of basic rescue procedures to be used following accidents at surface and underground mining operations. It will also serve as a guide to good practices at any time when people are in a physically dangerous situation and must be moved to a safe place. Mine rescue work is demanding and at times dangerous. Mine rescue teams are highly trained and skilled personnel. They must have an intimate knowledge of their equipment and master all the skills required to accomplish their rescue missions, although they may never be required to put their training to use. In fact, only a small percentage of miners who have received mine rescue training will ever be called upon for actual rescue work. Nevertheless, if the need should arise, rescue teams will be ready to go to the aid of their fellow workers. -
Mine Production Improvement Through Haulage Optimisation
THE UNIVERSITY OF QUEENSLAND Bachelor of Engineering Thesis Mine Production Improvement through Haulage Optimisation Student Name: Matthew CORNELIUS Course Code: MINE4123 Supervisor: Associate Professor Mehmet Kizil Submission date: 9 October 2017 A thesis submitted in partial fulfilment of the requirements of the Bachelor of Engineering degree in Mining Engineering UQ Engineering Faculty of Engineering, Architecture and Information Technology i ABSTRACT A drop in commodity price forces companies to increase production yet, in doing so, they lose focus of maintaining an efficient operation. An operation that is not meeting production targets should first analyse the current assets prior to purchasing new ones to understand where the shortfalls are present and if there are any improvements that can be implemented. The project aims to close the gap between underperforming operations by adopting an end-to-end approach, considering all inputs and each associated effect and understanding variations within the project that may be controllable or uncontrollable. If operations more often reach the best practice benchmark they become more competitive in today’s market and ensure a more viable operation. The Central Queensland coal mining operation produces 11Mtpa coal and 30Mbcm annually utilising a trucking fleet of 12 and two Hitachi EX5500 excavators in backhoe configuration with a bucket capacity of 27m3. The site has control over the load, haul and dump processes and thus it is imperative these are optimised such that maximum profitability is attained. Current site practices involve working two 12 hours shifts where over the course of the shift tasks are recorded manually using the reporting software InfoMINE and adjusted using Vital Information Management Systems (VIMS) and survey volume adjustments.
