INNOVATIVE TEACHING

CONCEIVE-DESIGN-IMPLEMENT-OPERATE II

The aim of the CDIO II project was to raise awareness of the principles of good, contemporary teaching in modern raw materials education. CIDO, an international framework program with 12 standards, stands for Conceive Design-Implement-Operate and thus for what engineers should be able to do after their training, namely to solve and overcome problems and challenges in a real, complex, industrial and international environment.

The project was the first to apply the principles to European raw materials education. Faculty Development courses took place at the participating universities, joint project courses with industry participation were offered, a worldwide overview of the use of laboratories in the training of mining engineers was developed, and guidelines for innovative laboratories as learning environments were developed.

REAL TIME PROCESS CONTROL IN MINING

As part of the Real Time Mining project, a real-time system was developed over 48 months as part of a Horizon2020 funded project, which enables process control of the entire mining process. The focus was on the collection of material, location and machine information during the extraction process in order to sequentially optimize the deposit model developed from the exploration. With the help of this information, it is possible to adjust the long-term and short-term planning of the extraction in real time.

MATERIAL IDENTIFICATION

CUTTING DRUM 4.0

As part of the project Cutting Drum 4.0, steps have been taken towards developing an intelligent cutting drum that is equipped with sensors suitable for mining, so that, for the first time, material recognition can be realized directly during the cutting process. By distinguishing between coal and secondary rock during the cutting process, more efficient extraction can become possible. As part of the development of such a cutting drum, the relationships between different material classes and the AE signals had to be identified and evaluated right at the cutting tool.

BLUE NODULES

As part of the Blue Nodules project, the Institute for Advanced Mining Technologies (AMT) developed a concept for characterizing the material flow using acoustic emission technology in deep sea environments. Acoustic emission sensors have so far been used, for example, in the condition monitoring of pressure vessels and bridges. In the first preliminary tests at the AMT Institute, the physical phenomenon of acoustic emissions was used to characterize the material flow of bulk material. The AE signals recorded during transport and impact processes are evaluated with regard to characteristic parameters. Characteristic values are calculated and compared with already recorded characteristic values from previous reference measurements. The aim here is to determine differences and thus characteristic parameters for different materials. This concept has now been adapted for use in the deep sea to characterize the material flow of manganese nodules and overburden. The results will be used to determine the process efficiency and, if necessary, to control the process.

ONLINE MATERIAL CHARACTERIZATION

The goal of the project OMMA is the development of an online measuring system for material flow characterization in processing plants of the gypsum industry. The background for the need of such a system is the necessary quality assurance of the products in companies of the primary raw material industry. A precise knowledge of the composition of the raw materials to be processed is crucial. The aim of the OMMA project is therefore to implement a real-time measurement system integrated into the preparation process for inline characterization of the material flows.

AUTOMATION

MAINTAINED MINE AND MACHINE

The goal of the project MaMMa (Maintained Mine & Machine) is to improve the availability, efficiency and safety of machines and mines through the use of an intelligent, integrated and holistic maintenance system. Unexpected and unplanned machine and infrastructure failures are the main cause of costly underground failures and are to be minimized by the software system developed in the MaMMa project. At the same time, the system enables employees and consultants to better and more efficiently plan maintenance work based on real-time data on the condition of machines and equipment underground.

PARTIAL AUTOMATION OF CONCRETE SPRAYING EQUIPMENT

Today, concrete spraying processes in mining and tunnelling are still carried out manually. The shotcrete application and the quality control are subject to the subjective impression of the operator. A sufficient examination of the quality of the working process cannot be guaranteed in this way. In order to support the operator and increase the success of the process as well as the quality control, GTA Maschinensysteme GmbH together with the Institute for Advanced Mining Technologies of the RWTH Aachen University developed a novel concrete spraying vehicle equipped with various sensors. This made it possible to record the tunnel profile, monitor the application of the shotcrete slab and carry out a final, data-supported quality control. In this project, AMT was responsible in particular for the development of the localisation technology consisting of Ultra-Wide Band (UWB) and INS, including skilful sensor data fusion. In addition, the laser scanner technology and the associated software were developed at AMT. Special attention was paid to the algorithms and time synchronization of the UWB modules.

PREDICTIVE MAINTENANCE

SMART TELESCOPIC BOOM (TS4.0)

The aim of the project "The intelligent telescopic boom for extreme operating conditions" was to develop a robust, self-monitoring and 360 degree endlessly rotatable telescopic boom for adverse environmental conditions in the extractive and related industries. The new development is intended for underground use in gypsum-anhydrite mines around the world for depletion of roadways and mining sites.

The telescopic boom enables the use of new, particularly efficient tools such as the "Xcentric® Ripper", which requires special design consideration due to its high-frequency mechanism. At the same time, the radius of action of the telescopic boom is increased by extending the telescopic stroke.

OBSERVER-BASED CONDITION MONITORING SYSTEM

The research project "Observer-based Condition Monitoring System for Main Transmissions in Wind Turbines (BCMS)" was carried out within the framework of the 6th Energy Research Programme of the Federal Government with the focus on an environmentally friendly, reliable and affordable energy supply.

The research project dealt with the development of a novel, integrable condition monitoring and prognosis system for main gearboxes of wind turbines. In order to achieve sufficient reliability in the prediction of component damage and failure, the observer-based methodology was used, in which data from simulations running parallel to the measurement are used to map a fault-free WTG system. Deviations of the measured, real plant behaviour compared to the simulation are used for fault detection and condition prognosis. Thus, the accuracy and the scope of information of condition monitoring systems on WTG main gearboxes could be increased and an automated and reliable damage reporting system could be made possible.

SMART TOOL FOR PROGNOSIS AND ANALYSIS (SiZu)

The aim of the SiZu research project was to develop an integrated forecasting and analysis tool for assessing machine conditions. For this purpose, the AMT (at the time IMR) for the first time combined condition monitoring and real-time simulation in a single system and made them jointly evaluable.

The System Condition Analyser provides a comprehensive and meaningful database, on the basis of which the project team was able to develop new maintenance strategies. With the development of the Condition Analyser, the AMT pursued two core objectives:

  • The development of a condition forecast oriented maintenance strategy
  • The Development of an Automated Failure Cause Analysis

CONDITION MONITORING OF ROLLING BEARINGS (MAEX)

The aim of the research project was to improve the condition monitoring of rotating and oscillating rolling bearings using acoustic emission technology. By early recognition of a developing damage suitable maintenance measures should be carried out promptly or larger repairs should be planned according to demand. The direct and indirect maintenance costs saved as a result increase the economic efficiency of the plant.

MEASURING SYSTEM FOR CONDITION MONITORING (i-MaSS)

Unplanned shutdowns or sudden plant failures in mining plants quickly cause very high costs, which must be avoided. Although the measuring systems used for condition monitoring cover a wide range of possible applications, they reach their limits in special areas. The i-MaSS research project addresses exactly this problem. An interdisciplinary consortium from the fields of raw material technology, mechanical engineering and electrical engineering developed a cost-effective, miniaturized, adaptive and self-sufficient measuring system for improved condition monitoring.
