The Katowice conurbation is situated in the Upper-Silesian Coal Basin, in a region which had high rate of water inflow in the pre-mining period. In order to make deposits of mineral resources accessible, it was, and still is, necessary provide mines with a draining system, which now reaches as deep as 1200 m. The area of the depression sink which was thus created is about 1200 km2. Currently, all metal ore mines within the conurbation, as well as part of coal mines, have been closed down, but water which flows into them is still pumped out due to the legal obligation to protect neighbouring operating mines. After the operation and drainage of mines cease, water coming to abandoned excavations will begin restoring static reserves in the orogen, which, depending on hydrological conditions, will take between several and a few dozen years. As the level of underground water rises, the process of subsidence of old shallow mining excavations will intensify, and many depressions may appear in highly urbanized areas. In areas of mining subsidence, the underground water-table will be close to the surface, causing flooding of basements and building foundations, and the deepest subsidence basins will probably be completely flooded. Current location of operating mines on the northern and southern sides of the conurbation with the central belt of drained excavations is unfavourable for its sustainable development. A solution, which would make it possible for the conurbation to grow, would be to close down and flood the mines on the northern side as soon as their mining concessions expire, which will be in early 2020s. Then, the area would regain its original stability within a decade and all kinds of construction activities could be carried out there. That, however, requires authorities of municipalities to object to the extension of concessions for mines, which may be impossible to obtain due to fears of social discontent resulting from miners - residents of those municipalities - being made redundant.

In 1926-1932, Rosikoń studied at the Department of Civil Engineering and obtained a degree in civil engineering. After graduation, he worked as a trainee at the District Administration of State Railways in Katowice, then as a road inspector at the Road Department in Tarnowskie Gory, where he designed a makeshift load-bearing track and also a device for measurement of track irregularities. In 1939, he became head of the Cieszyn-Zachod Road Department. After Germany’s invasion of Poland in 1939, Rosikoń supervised evacuation train taking out of the country Polish railroad men and documentation from the lands occupied by German troops. During occupation he worked at the iron ore mine in Żarki. After liberation, as deputy of the head of the Polish State Railways in Katowice District, he supervised the reconstruction of damaged railway infrastructure. From September 1945, he was a lecturer at the College of Advanced Technology in Katowice. In 1948, he returned to work on the railways. He gradually obtained more and more experience and became a specialist in damage of railway infrastructure caused by mining. He was a member of the Polish Academy of Sciences and of the Committee on the Protection of Surface at the State Mining Authority. In 1961, he was appointed Director of the Office of Railway Planning in Katowice; he designed road and railway infrastructure for the Rybnicki Mining District. In 1964, Rosikoń defended a doctoral exam at the Silesian Technical University. After going into railway retirement in 1967, he began his work at the Silesian Technical University, where he founded Railway Construction Department. For some time he worked at the Industrial Transport Department. Shortly before reaching retirement age, he became the Director of the Road and Bridge Institute at the Construction Department of the Silesian Technical University. In 1977 he retired but he was still professionally active and was giving lectures until 1982. In the years 1979-2000, Rosikoń was Deputy Director for technical affairs at the New Technologies and Implementation Department of Gomex company, and then Polon and Armex companies. In 2001, he was appointed to the professorship of technical sciencesand in 2007 received an honorary award „Człowiek roku-przyjaciele kolei” (“Man ofthe Year – Friends of Railways”). In 2009, Rosikoń was honoured with a title and medal “Osobowość Budownictwa Śląskiego” (“Personality of the Silesian Construction Industry”). In 2008, he was decorated with the Commander’s Cross of the Order of Polonia Restituta. On October 2, 2012, he was awarded by the University’s senate a title of the Honorary Professor of the Silesian Technical University. Antoni Rosikoń died on August 17, 2013 in Mysłowice. At the moment of his death he was the oldest professor in Poland. Keywords: railway technician, mining damage, communication construction
