Activation of a dewatering well with the skinaut clay mineral disintegration agent
(Wydawnictwa AGH, 2024) Macuda, Jan
The drilling of hydrogeological boreholes by rotary methods and with the use of drilling mud impairs the permeability of water-bearing rocks in the near-hole zone. This is mainly caused by the penetration of solids and mud filtrate into the pores or fractures of the drilled rocks. Consequently, the depression increases, and the hydraulic efficiency of the borehole drops, leading to the reduction of well productivity. As a means of improving the damaged permeability of rocks in the near-hole zone, a clay mineral disintegration agent called SKINAUT was developed and patented. To evaluate its effectiveness in industrial conditions, a test was carried out to activate a dewatering borehole for intaking water from loose formations at the Szczerców open cast. The applied chemical helped to decolmatate the pore medium and lower the hydraulic resistance of the borehole, resulting in a reduction in depression and a significant improvement of its hydraulic efficiency.

(2005) Gonet, Andrzej; Lewkiewicz-Małysa, Aleksandra; Macuda, Jan
Mineral waters quite commonly occur in Poland, especially below groundwater layers. They are widely used in industry as chemical and medical material and utilized as waters for consumption purposes. As chemical material they are employed in producing table salt, as well as iodine, brome, magnesium and other chemical elements or compounds. As medical material they are applied in health-resort medicine. Recently mineral waters, especially those of low mineralization level, have been used on a large scale for consumption. The geological conditions of Krosno region have been presented in the paper and mineral waters occurring in Ciężkowice sandstones have been characterized as well. The physico-chemical composition of particular mineral waters that occur in the regions of Iwonicz and Krosno, have been compared and analyzed as to evaluate the exploitation possibilities of these waters in Krosno for drinking and balneological purposes. Water from the Mac Allan 4 water bore can be used for mineral water drinking cure, while water from the Mac Allan 11 water bore can be used for production of iodine-brome medical salt.

Analysis of the acoustic climate during the drilling of gas wells in post-mining areas
(Wydawnictwa AGH, 2017) Macuda, Jan; Łukańko, Łukasz; Hendel, Jacek
Coal mine methane from post extraction coal gobs is most efficiently produced with drilling wells realized from the surface. In Polish conditions, such wells are most frequently drilled in highly urbanized areas and residential quarters. The drilling of such wells creates the hazard of exceeding admissible noise levels in the areas requiring acoustic protection during the day and night. Therefore it is very important to assess the level of noise emitted by the rig and to establish the isophones 45 dB and 55 dB for various field conditions. With such information, the location of the rig can be properly selected at the stage of well design. The level of noise emitted in the environment during the drilling of experimental gas well Wieczorek-AGH-1, was established on the basis of noise analyses performed within the well pad area and its closest vicinity with the reference method, described in the Regulation of the Environment Minister of 30 October 2014 concerning the requirements of the analyses of emissions and the quantity of water consumption (Official Journal of 2014, item 1542), hereinafter called the Regulation.

Assessing the impact of expressway construction and operations on groundwater intake
(Wydawnictwa AGH, 2023) Łukańko, Łukasz; Macuda, Jan
Wydział Wiertnictwa, Nafty i Gazu
Expressways represent significant public investments contributing to the socio-economic development of a country. However, their construction and operations exert detrimental effects stemming from the road surface onto the adjacent groundwater environment. To mitigate these adverse environmental consequences, extant legal restrictions are factored in during the expressway design phase, accompanied by the implementation of modern technical and organizational solutions. As a pivotal legal instrument, the environmental impact assessment is mandated in the procedural framework for obtaining approval on environmental conditions during expressway construction. The precision in evaluating the negative impact of an expressway on distinct environmental elements hinges on the depth of the assessment, influencing the nature and extent of planned protective measures. In many instances, supplementary environmental risk assessments are conducted to bolster the investment process. This study aims at discerning the specific impact of expressway construction on nearby groundwater intake. To achieve this, an exhaustive assessment of contaminant migration times from the land surface to the aquifer and within the aquifer itself was executed. Subsequently, a proposal for aquifer monitoring was formulated based on the findings to enable the early detection of potential shifts in groundwater quality, facilitating timely preventive interventions.

Auxiliary gravity drain and infiltration wells supporting basic drainage system in the «Bełchatów» Lignite Mine
(Wydawnictwa AGH, 2018) Macuda, Jan; Gasiński, Jerzy; Grad, Janusz; Szewczyk, Sławomir
The downhole parts of the «Bełchatów» Lignite Mine are dewatered through large diameter dewatering wells belonging to the primary drainage system. This system is supported by additional shallow wells performed in the overburden, in the forefield of extraction site or on the extraction site itself. They are used for limiting and removing residual water from extraction site, which corresponds to the height of excavator level. They are preceded by the analysis of dewatering of the mining benches based on the results of control drilling and observation of the water table in the existing piezometric wells. Shallow auxiliary wells are drilled with the »dry« rotary method to about 30 m of depth. Such wells considerably reduce the amount of water coming to the mine with rainwaters, and which were not captured by wells of the primary drainage system. This is mainly caused by such factors as complex geological build, disturbed system of strata, presence of synclinal structures and closed lenses. The technique and technology of drilling supporting shallow wells with the »dry« rotary method and their effect on dewatering of active extraction sites are discussed in this paper.

(2010) Macuda, Jan; Zawisza, Ludwik
The operational technological systems for treating natural gas in gas fields are a source of potential ground contamination with inorganic and organic substances. They may leak from broken or untight industrial installations used for separating and storing formation fluids, drying and regeneration of glycol as well as drying of natural gas and then to penetrate the environment. The results of analyses of the quality of ground environment within the technological installation of the Paproć Group System are presented in the paper. Samples for environmental analyses were taken in the close vicinity of main technological installations. The obtained results of chemical analyses of soil and ground samples were compared with the quality standards for grounds and silos for industrial areas.

Badania gleb i gruntów w rejonie miejsc wieloletniego składowania odpadów wiertniczych i poeksploatacyjnych
(2012) Macuda, Jan
W drugiej połowie XX wieku w trakcie wiercenia otworów poszukiwawczych za ropą naftową i gazem ziemnym powszechną praktyką było składowanie powstających ścieków i odpadów technologicznych w dołach urobkowych na terenie wiertni. Doły te nie były skutecznie zabezpieczone przed migracją z nich toksycznych odcieków do środowiska i wokół nich dochodziło do zanieczyszczenia gruntów i wód podziemnych. Zasięg i wielkość zanieczyszczenia każdorazowo były uzależnione od ilości i toksyczności składowanych w dołach urobkowych ścieków i odpadów oraz warunków geologicznych i hydrogeologicznych występujących w miejscu ich lokalizacji. Dla ograniczenia negatywnych skutków dla środowiska gruntowo-wodnego, składowane ścieki i odpady były zestalane w dołach urobkowych przy wykorzystaniu różnego rodzaju materiałów wiążących. W artykule przedstawiono wyniki badań stanu jakościowego środowiska gruntowo-wodnego w obrębie dołu urobkowego zlokalizowanego na trenie KRN Grabownica, w którym składowano zestalone odpady wiertnicze i poeksploatacyjne. Wyniki badań chemicznych próbek gruntów i wód podziemnych porównano z obowiązującymi aktualnie standardami jakościowymi środowiska gruntowo-wodnego dla obszarów przemysłowych.

Badania jakości wód podziemnych w rejonie Czarnej
(2007) Macuda, Jan; Winid, Bogumiła
The hydrocarbons and the related horizons of formation and edge waters in the Carpathians cause that this region is very specific as far as hydrogeology is concerned. There occur regular waters, waters of increased mineralization, therapeutic mineral waters as well as native waters and saline waters. Their applicability is mainly related with their chemical composition. The concentration of specific elements and their interrelations illustrate processes taking place in water as it is running, and also its quality. The results of analyses of chemical composition of groundwaters sampled in two (partly closed from the bottom) oil wells KRN Czarna, i.e. No. 5 and 67, springs Pod Kieratem as well as a new well S-1FŻ are presented in the paper. On this basis they were assessed qualitatively in view of their usability as regular drinking water, mineral water or therapeutic water.

Badanie zmian chemizmu wód podziemnych w rejonie składowiska odpadów przemysłowych
(2005) Macuda, Jan
Industrial waste is environmentally noxious. This mainly refers to waste produced by chemical industry, mainly phosphatic fertilizers and plastics. Such waste contains considerable amounts of washable organic and inorganic components. Seepages penetrating the groundwaters from untight or badly sealed landfills contain ammonia, arsenic, chromium, lead, copper, zinc, iron and organic compounds. The results of groundwater monitoring of groundwaters near the analyzed landfill show their qualitative changes and the measures for improving it. The obtained results can be a basis for further decisions regarding the reduction of the negative impact of the landfill on groundwaters and surface waters.

Drainage wells as an integral part of a deep dewatering system in Szczerców field in the Bełchatów Lignite Mine
(2017) Gasiński, Jerzy; Macuda, Jan; Szewczyk, Sławomir
The open-pit extraction of lignite in the Bełchatów Lignite Mine can be conducted after prior deep dewatering of the rock mass, realized with large-diameter dewatering wells distributed in the form of outer and inner barriers. This type of dewatering system allows for safe extraction of lignite, owever residual waters in the overburden may locally create hazard. These are rain waters infiltrating into the rock mass, and which, due to the complicated geological structure of the deposit and disturbed system of layers, were not intaken by wells belonging to the primary dewatering system. They are removed through the existing and newly drilled exploration wells, which are converted into drainage wells. Such wells are used for removing waters suspended in permeable overburden and avitationally moved to the lower absorbing layers, from where they are directed to the primary dewatering ystem wells and then to the surface water courses. The applied enhancement of the dewatering system used in the lignite deposit significantly improves the safety of mining works conducted in this place. Technical and technological aspects of drilling dewatering wells in Bełchatów Lignite Mine are discussed in this paper and followed by the evaluation of efficiency of dewatering of the overburden.
