SWIP5 (Seismic Waves Interpretation Program) is designed to work in seismological observatories, research institutes, and seismic hazard monitoring centers such as mines. The purpose of its development was to facilitate at various levels the analysis of seismic data. The use of SWIP5 ranges from elementary analysis to scientific research. Depending on the configuration the SWIP can be used at various stages of the seismic hazard investigation. During its design, we made efforts to combine experiences of mining and global seismology. The program is modular. It consists of a core enabling basic operations and controlling modules, which users can build independently, added or removed during the SWIP5 exploitation depending on the needs so that the user can create their functionality of the SWIP5. The program is now routinely used at the Institute of Geophysics of the Polish Academy of Sciences and implemented at the Central Mining Institute. The article presents how the program works and analyzes seismic data, the method of storing the results, and cooperation with other tools for the study of the seismic hazard.

Coal reservoirs are an important element of the technological process. Their walls may be contaminated with sediments from the mined coal (overhangs on the housing of tanks and even jamming at their outlets) hindering their operation, which results in disturbances of the mine’s operations. The applicable regulations impose an obligation on the entrepreneur to carry out a periodic inspection of the condition of coal reservoir housings. Each inspection is preceded by thorough cleaning of their housing, ensuring safety of the inspectors and reducing the problems related to the operation of the tanks. In the mining industry, inspection of brickwork of reservoirs is carried out in one of three ways: from the pile of mined coal accumulated in the tank, from a mobile platform suspended on ropes attached to beams that are built into the ceiling of the chamber above the reservoir, or using industrial mountaineering techniques. The article describes the use of mountaineering method on the example of Hard Coal Mine “Pniówek”. Cleaning and inspection of reservoirs is carried out here by specialised rescue teams for operations in vertical workings, on action basis. Their plan is reviewed each time by the district mine rescue station. The actions are carried out by specialised rescue teams. Owing to this, their members can improve their skills, work out and consolidate the procedures. All this together allows for carrying out the work safely with the use of mountaineering techniques, and ensures uninterrupted operation of coal reservoirs.

The salinity of the waters flowing into the mine workings of PGG S.A. Branch of HCM “Piast-Ziemowit” Ruch Ziemowit in Lędziny increases the deeper it flows. Mine draining is carried out by a system that allows for selective collecting and separating fresh and saline waters. Saline and moderately salty waters, caught in the main drainage pumping stations, are discharged to Goławiecki Stream or a holding and dosing reservoir Wola. However, fresh waters flowing into the areas of closed shafts “Hołdunów” and “Piast II” are caught in the auxiliary pumping station at shaft W-I and transferred to a water treatment plant. Treated water, meeting the requirements of water fit for human consumption, feeds the drinking water network used by the employees of the mine and residents of Lędziny, and has also been bottled since 2018. Owing to filtration, the water is clean and rich in minerals. In order to ensure its properties and suitability for consumption, the water’s quality is monitored systematically. Freshwater not meeting the requirements of water intended for human consumption is used for industrial purposes or discharged into the environment.
