“…The Water Hazard Before 2010, there had been six inrushes of water into shaft mine workings in the USCB. Water hazard assessment in active shafts in USCB mines has been described by Bukowski (2011). The event which became the basis of the analysis described herein had two stages.…”

Central Europe experienced catastrophic rainfalls and flooding in 2010. This paper discusses a decommissioned shaft that was flooded by surface water, which led to displacement of shaft backfill and an inrush of large amounts of water into an underground pumping station. The weather conditions for the period preceding the inrush, the hydrogeological conditions, the quantity of water that entered the mine dewatering systems, and the underground hydraulic connections are all described. Uncontrolled inflow of water as a cause of backfill saturation and the hazard for active underground infrastructure were analysed. A need to rebuild damaged infrastructure was identified. The case study highlights the need to improve underground mine closure requirements to ensure safe conditions above ground, particularly in densely populated areas.

“…Under favourable conditions, stationary systems in the decommissioned mines were replaced with deep-water drainage. This reduced costs, while increasing safety and retention capacity in the case of an uncontrolled, rapid inflow (Bukowski 2011;Frolik and Kubica 2005).…”

“…In mines situated in subregion II, as well as among water rich formations of Cracow Sandstone Series and mines planned to be built outside the regional cone of depression, they are important for safety of mining safety. Their huge significance within the area of subregion II is a consequence of the fact that the younger aquifers (Quaternary, Miocene), often demonstrate quick condition, and the threat they pose to shafts of the mines located there (Bukowski, 2011).…”

“…Evaluation of conditions of water filtration with the research method enables building a credible numerical model of a dump watered with underground water. The basic aim of devising and applying the method was evaluating water filtration through backfills of closed shafts of high water inflow and using it evaluate water hazard associated with closing shafts (Bromek & Bukowski, 2002;Bukowski, 2011).…”

Water hazard has been accompanying underground mining since the first mines were built. The hazard is particularly often in the areas of mines situated in hydrogeologically outcropped part of USCB and in water rich formations of Cracow Sandstone Series. To plan properly mining actions and technical measures at each stage of life of a mine it is necessary to evaluate hydrogeological and geomechanical conditions and their changes. The conditions determine formation, occurrence and volume of the most serious sources of water hazard. Symptoms obtained in geomechanical tests and observations of forming and dewatering reservoirs of underground water, show that it is necessary to update constantly evaluation and classification of sources of water hazard or the state of water hazard in the coal mines of USCB.Development of underground mining in , which resulted in a quick increase in production, determined development and the range of influence of mining operations on the rock mass and the influence on the state of drainage and saturation of the rock mass. The result of the changes was an apparent influence on the changes in the state and shaping water hazards in the course of time. Since 1989 economic conditions of functioning of mines have been tightly associated with the conditions and rules of market economy. As a result of each of the so-called restructuring of mining activity a certain number of mining companies was closed, merged or split. The consequence is that in the vicinity of active mines and prospective mining areas, more and more often there are partially or completely flooded abandoned coal mines. Flooded coal mines have changed and still do hydrogeological conditions of their surrounding and force active mining companies to introduce changes in mining activities they are planning and conducting. The current state of flooding mine workings, is a result of realizing previous plans of restructuring mining industry, and all the changes of the state require hydrogeological documentation and evaluation of water hazard.In the today's conditions of functioning of mining industry, sources of water hazards like water reservoirs in goafs, are one of six main types of sources of hazard, and at the same time the biggest problem and the most serious threat for active mine workings. As the hydrodynamic conditions in the closed areas stabilise and the water piles up close to the surface, an increase in the influence of reservoirs on the state of environmental and public hazard (subsidence, overflowing, flooding, pollution of water in the aquifers located in the overburden and surface water).As there is a qualitative change in the directions, causes and sources of water hazard, it shall be expected that the changes will tend to increase the threat level from the closed mines. Hence since

“…Bukowski [16] proposed an assessment system to classify mine shafts with respect to water hazard risk. Li et al [17] integrated the artificial neural network (ANN), wavelet, analysis and fuzzy mathematics -namely the fuzzy wavelet neural network (FWNN) -which was then used to establish a model for risk assessment on karst tunnels.…”

With the rapid development of China's economy, more and more long-deep tunnels are under construction, especially in the mountainous area of western China and in karst areas [1][2], which pose a great challenge for tunnel engineering. Long-deep tunnels are always buried in complex geological conditions with high geo-stress, high water pressure, strong karst geology, and construction disturbance [3]. Additionally, it is quite difficult to make a Pol. J. Environ. Stud. Vol. 26, No. 4 (2017) AbstractWater inrush is one of the typical geological hazards of tunnel construction in karst areas. It is necessary to predict water inrush more accurately for karst tunnels. Firstly, we created a model on risk evaluation of water inrush based on the efficacy coefficient method. Then karst hydrologic and engineering geological conditions were considered in detail, and several typical factors were selected as evaluation indexes, including formation lithology, unfavorable geology, groundwater level, and so on. Moreover, the weight coefficients of the selected evaluation indices were calculated using the analytic hierarchy process method. Furthermore, the total efficacy coefficient was presented to specify the risk grade of the evaluation samples. Finally, the risk grade of water inrush for karst tunnels is divided into four levels: severe (red), high (orange), elevated (yellow), and guarded (blue). Additionally, the model of risk assessment of water inrush was applied to Jigongling tunnel along the Fanba Expressway in China. The results show that the present evaluation results agree well with the construction situation, which also agree with the relative analysis results of attribute mathematical theory. The presented work with the efficacy coefficient method is relatively simple with strong operability, which has potential for predicting water inrush in karst tunnels.
