Arrival and welcome barbecue
The participants arrived on 8 July at Leipzig International Airport where Dipl.-Hyd. Susanna Kettner welcomed them and accompanied them to their accommodation.
In the evening the CEMEREM team and students of HTWD and friends invited the guests to a welcome barbecue. Planning, chatting, singing and a bit of dancing went until it was time to have a break to be prepared for an early start the next day.
9 July – HTWD
The day started with a photo session and a welcome note by the Rector of HTWD, Prof Stenzel. At 9:15 Prof Feistel officially opened the first CEMEREM summer school outlining the programme and expressing her wish for a lively discussions and an exchange of ideas.
The morning session was opened by Prof Grischek (HTWD) with a lecture on “post-mining water issues in Lusatia, Germany” followed by Prof Bongaerts discussing “Financing and Financial Reporting related to Mining Projects”.
After a break, Prof Feistel and Dr Liu continued with “Judging and Addressing Climate Change”. The lecture series was completed by Mr Oscar Choque, one of Saxony’s promotors of resource markets, development and migration presenting his thoughts on “Implications of digitizing and e-mobility for raw materials from developing countries – Socio – economic and ecological implication for mineral producing countries”. All participants took part in a lively discussion, which could not be finished and continue throughout the visit.
After lunch, the programme was tailored to the participants’ background and the group split for the afternoon.
One group visited the DREWAG power station Nossener Brücke, a combined heat and power plant where they get an insight into the German energy and heat market.
Participants with a background in agriculture went with Prof Schmidtke to the experimental fields and laboratories of the Faculty of Agriculture/Environment/Chemistry in Dresden-Pillnitz were a lively discussion went on until late in the evening.
A third group were introduced the concept Industry 4.0, by discussing „New technology trends at SAP in the model factory Fischer”. The concept Industry 4.0 plaid a prominent role throughout the week and was investigated from different perspectives such as in the context of production by the company Bosch-Rexroth and later at the underground mine.
10 July – Excursion to open pit lignite mining
At 7:00 on a cold and rainy day the bus left for Lusatia where the visit of the opencast lignite mine Welzow-Süd started with an overview given by Mr. Brendler. He presented key figures such as the annual production of coal, its distribution and use and explained the economic conditions under which operations are currently taking place. He introduced the participants to the hydrological aspects of operations and presented details of the geology.
Following the introduction a personnel carrier took all into the mine where Mr. Brendler explained the techniques and machinery used to remove the overburden and to extract the lignite.
After lunch, the excursion continued with the exploration of the post-mining re-cultivation efforts. Herr Lückfeldt first outlined the legal framework for re-cultivation and then explained the process of land reclamation, the different uses and the outlook into the future.

11 July – Feed-back excursion, poster session, visit waterworks
The morning session started with a summary of the excursion to Welzow-Süd given by the participants followed by a lively discussion of different aspects of the economy, mine planning and operations, environmental issues as well as the link to potential lignite mining in Kenya.
Mr Eric Kinyua, Mr Shadrack Mwagandi, Dr Anne Kelly and Dr Justin Maganga presented some of their ongoing research.
The presentations were followed by the poster session. Students had prepared a poster with their work and each poster was briefly presented and results and ideas discussed.

After the poster session, the participants welcomed two guests from industry to share their experience and exchange views.
Dr. Eckehard Büscher, director Networks Mining and Energy Sector, EnergieAgentur NRW talked about the present challenges such as a reduction in efficiency in mining exploration by 28% in recent years and potential solutions making the link to the industry 4.0.
Frau Dr Luise Stadlbauer, Sales Area Manager, Africa and Eastern Europe DC/SSD4 Bosch Rexroth presented her company with a particular focus on training concepts in various fields such as mechatronics. She too made the link to the industry 4.0 in the context of modern efficient production.

In the afternoon Dipl.-Ing. Jakob Ebermann and Dipl.-Ing. Philipp Marx discussed each poster with the author individually whereby the focus was on scientific standards regarding the design and layout.
12 July – TU BAF
In the morning, the Participants from SSI, SBESS, SME travelled to Freiberg for a tour in the underground mine at “Reiche Zeche”, which was used for extraction of silver in the past, now is used as the biggest laboratory at TU BAF for teaching and research. The tour started in the shaft 145 Meter below sea level. The tour was leaded by Mr. Lasse Eggers. He introduced the geology of the silver deposits, the mineralogy of the actual veins, as well as the history of the mine and the development of the mine technology. The tour took more than 2.5 hours. The participant climbed from 145 meter up to 100 meter deep in the shaft, they followed the traces of the miners of 16th to 19th century. All participants were impressed by the hard working condition in the darkness of the miners. The tour was
complemented insights into todays exploration technics such as autonomous exploration by Mr. Marc Donner.
After lunch, they were shown a simulator for excavation. Prof Horst Beidatsch accompanied the group.
Students from SAEES went to Hilbersdorf to see how drones are used in agriculture and then visited farms where organic farming and social equality play a key role.
13 July – TU BAF
In the morning, the participants had the opportunity to learn about energy production with biogas in praxis. They visited two biogas plants of Agrargenossenschaft Clausnitz with different capacities. Prof. Bongaerts guided the tour. He introduced the function of biogas plants and explained how the energy market works in Germany and how the renewable energy is integrated.
In the afternoon Thomas Lauterbach, Regional Sales Director Africa & Middle East; Putzmeister Solid Pumps GmbH joined the group. He introduced the technical concept of pumping solids and semi-fluids applied in particular in the mining and construction industry. His company is already present in the mining sector on the African continent.
A workshop and brainstorming on renewable energies in mining was the offered by Kateryna Zharan and Dr Liu to address a topic which plays a prominent role in the development of the mining sector in Kenya.
At the following closing session all participants of the summer school received a certificate of attendance. The best posters judged by their content, layout and also presentation had been selected by a jury and prizes were given to:
- Ms Mariam Ali Ragunda (best poster and presentation),
- Victor Opiyo Orwa and Ms Patricia Nasubo Imelda and (second place)
- Mr Wicklif Otieno Onyango (third place).
