Opis:: The rock burst that occurred on November 29, 2016, in the "Rudna” copper mine has had tragic consequences. Eight miners were killed in the heavy machinery compartment located in the safest area of the safety pillar. This is not the first accident of its kind. It was caused by the collapse of the overlying anhydrite layer that is approximately 200 m thick in this region. The mining operation is based on the room and pillar system that results in stress accumulation within the anhydrite layer, which, at some time, causes a rock burst. The best method to prevent this phenomenon is the use of backfill. The entire mined surface of a deposit is greater than 100 square kilometres. Such amounts of sands are not stored within the mines. It is therefore necessary to carry out operations to adapt more than 1 billion tonnes of tailings accumulated in the "Żelazny Most” reservoir to the needs of backfilling of mine workings. The widespread use of hardened backfill should prevent such great rock bursts in copper mines.

Opis:: The development of coal mining and power industry contributed to the accumulation of significant quantities of mining and processing wastes on the land surface in Wałbrzych and Boguszów Gorce. The main components of the mine waste dumps are gangues rocks and in smaller quantities: post-flotation waste and slag and ashes. Approximately 85 million cubic meters of such waste are disposed on the dumps with a volume over 1 million cubic meters. Approximately 3.4 million cubic meters of coal sludge and ashes remains in the bowls of former sedimentation tanks. The majority of the waste (81%) is located in the area of Wałbrzych. In the years 1975–1996, only approx. 1% of the waste from the mine waste dumps and sedimentation tanks was used for various purposes. Significant amounts of the waste accumulated on the land surface can be considered as prospective anthropogenic deposits. This is indicated by the attempts made so far to use them as secondary raw materials as well as by few studies providing the information for what purposes the waste can be used. It is therefore necessary to carry out detailed identification works on the quality and quantity of the deposited wastes, what is a prerequisite for the optimal use of these wastes in the future.

Opis:: Analysis of physical and chemical properties of water runoff samples collected in the vicinity of a spoil heap near the coal mine in Libiąż showed that they represented a classic example of acid mine drainage. For the first time in the Upper Silesian Coal Basin, it has been documented that rainwater in contact with a surface layer of waste containing pyrite (FeS2) and scarce carbonate phases, produces strongly acidified wastewater. This process is accompanied by a dramatic increase in the concentration of dissolved ions (eg. Cl-, SO , Fe, Al, Mn). Further geochemical changes occur in the ditch collecting water runoff at the base of the heap. At this stage, oxidation of pyrite catalyzed by bacteria, followed by hydrolysis of iron Fe3+ to form goethite (FeO(OH)) leads to conversion of the less acidic (pH 2.6-3.5), short-time retention runoff water into the aggressive stagnant runoff water (pH 2.1-2.8). Further disintegration of Carboniferous claystones occurs in the acidic stagnant water environment, leading to the decomposition of mineral phases containing heavy metals dispersed in the rock matrix and to mobilization of Zn, Ni, Cu, Cd, Co, and Cr.
