The paper presents new data on the Miocene development within the Upper Silesian Coal Basin. The Miocene succession of the study area is characterized by high thickness and highly variable lithology. In the Miocene sediments of the studied area, the presence of organic matter in the form of a coal layer, coal crumbs, and dispersed organic matter has been found. The research focused mainly on the analysis of organic matter in terms of its origin, degree of coalification, and depositional environment. the degree of coalification of organic matter was determined by the huminite/vitrinite reflectance. 136 Krzeszowska and Gonera 2022 / Gospodarka Surowcami Mineralnymi – Mineral Resources Management 38(3), 121–136 the hard brown coal layer with a thickness of about eight meters was identified within the Kłodnica Formation. Based on the textural properties and degree of coalification, brown coal was classified as dull brown coal and bright brown coal. Organic matter in the form of coal crumbs and dispersed organic matter were found within a package clastic sedimentary. On the basis of petrographic analysis, two types of allochthonous organic matter with different degrees of coalification were identified. The coal clasts are mainly of Carboniferous origin, while the Miocene redeposited brown coal grains dominate within the dispersed organic matter. Coal fragments and dispersed organic matter derived from the Miocene brown coal were also found within the black claystones. The study of organic matter of the Miocene sediments in the Upper Silesian Coal Basin showed both its autochthonous and allochthonous origins.

This article is the result of treatments on ground fissures for environmental protection and scientific shallow coal seam mining. In the southwestern mining area of China, the traditional longwall mining method has caused a large area of surface sinkhole, ground fissures, vegetation deterioration and disorderly coal gangue. To solve these problems, an integrated treatment technology that includes ground fissure treatment technology and underground backfilled technology was proposed as a solution. The technical principle and technical process were explained in detail; the ground fissure treatment technology involves a “three-step treatment method”, and the underground backfilled technology adopted a strip mining method with backfilling technology. The compression mechanical behavior of backfilled material, including coal gangue, fly ash and ordinary Portland cement, was studied; the mixed ratio of 1:0.3:0.18 was selected. In addition, the vertical stress, vertical displacement and plastic zone of the coal pillar were determined by FLAC3D numerical simulation, and a rational mining scheme of “11 m mining width, 2 m coal pillar width” was determined to be appropriate because of the lower vertical stress, smaller vertical displacement and better supporting capacity of the coal pillar. The monitoring results of ground sinkhole indicated that the maximal ground sinkhole deformation was 17.3 cm, and the deformation showed few changes after this technology was implemented. The treatment capacity of coal gangue and fly ash reached 821.150 t per year, and the vegetation survival rate of the ground fissure treatment area reached 85%. This integrated treatment technology could effectively control ground fissures and surface sinkhole as well as protect the environment.
本文是为了环境保护和科学开采浅层煤层而对地裂缝进行治理的成果。在中国西南矿区，传统的长壁开采方法造成了大面积地表塌陷、地裂缝、植被退化、煤矸石无序等问题。针对这些问题，提出了地裂缝处理技术与地下回填技术相结合的综合治理技术。详细阐述了工艺原理和工艺流程;地裂缝处理技术采用“三步处理法”，地下回填技术采用条带开采法配合回填技术。研究了煤矸石、粉煤灰、普通硅酸盐水泥等回填材料的压缩力学行为;选择混合比例为1:0.3:0.18。此外，通过FLAC3D数值模拟确定了煤柱的垂向应力、垂向位移和塑性区，由于煤柱垂向应力较低、垂向位移较小、支护能力较好，确定了“采宽11 m、煤柱宽2 m”的合理开采方案。地面塌陷监测结果表明，地面塌陷最大变形量为17.3 cm，该技术实施后变形量变化不大。煤矸石和粉煤灰处理能力达到821.150 t /年，地裂缝处理区内植被成活率达到85%。该综合治理技术可以有效控制地裂缝和地表塌陷，保护环境。

bioleaching research considers both the bioand anthroposphere in the search for novel ways to recover resources and elements, which is important to the concept of sustainable development. Since the efficient, cost-effective and simple recovery of resources is of increasing importance in the circular economy model, the bioleaching of metals is a method currently gaining interest. The process is also of importance considering the need for the neutralization of waste materials/resources that allow for their safe storage and use. In this study, Acidithiobacillus thiooxidans bacteria, which is commonly found and widely utilized in the bioleaching process due to its high tolerance to heavy metals, was used in a twenty-eight-day experiment. The manner in which bacteria inhabit incineration residues was observed using fluorescence optical microscopy and scanning electron microscopy. The concentration of elements in incineration residues and in the post-reaction solutions was measured using inductively coupled plasma mass spectrometry and the efficiency of element recovery was calculated based on the results. Municipal waste incineration bottom ash and sewage sludge incineration fly ash were considered in the experiment. The extraction rates were far from satisfactory, with the average 20 and 50% for bottom ash and sewage sludge ash, respectively. The obtained results were consistent with microscopic observations where the relative number of bacteria increased only slightly over time in the sewage-sludge fly ash and was barely observed in the bottom ash of municipal-waste incineration.

生物浸出研究同时考虑了生物圈和人类圈，以寻找回收资源和元素的新方法，这对可持续发展的概念很重要。由于资源的高效、经济、简单回收在循环经济模式中越来越重要，金属的生物浸出是目前人们关注的一种方法。考虑到需要对废料/资源进行中和，使其能够安全储存和使用，这一过程也很重要。本研究采用对重金属耐受性高、在生物浸出过程中普遍存在并广泛应用的Acidithiobacillus thiooxidans细菌进行了为期28天的实验。利用荧光光学显微镜和扫描电子显微镜观察了细菌在焚烧残留物中的生存方式。采用电感耦合等离子体质谱法测定了焚烧残渣和反应后溶液中元素的浓度，并计算了元素回收率。实验中考虑了城市垃圾焚烧底灰和污水污泥焚烧飞灰。底灰和污泥灰的平均提取率分别为20%和50%。所得结果与显微观察结果一致，在污水污泥飞灰中，细菌的相对数量仅随着时间的推移略有增加，而在城市垃圾焚烧的底灰中几乎没有观察到细菌的相对数量。Bioługowanie z wykorzystaniem ACIDIThIoBACIllUS ThIooxIDAnS - rozwiązanie dla odzyskiwania pierwiastków z wysokoalkicznych popiołów ze spalani odpadów?年代ło w z k l u c o w e生物ługowanie, Acidithiobacillus thiooxidans, popioł泽spalania osadowściekowych, popioł泽spalania odpadow komunalnych, surowce odpadowe S t r e S z z e n c e Badania procesow生物ługowania, analiza przenikania siębioi antroposfery, w poszukiwaniu nowych sposobow na odzyskiwanie zasobow我pierwiastkow。Granica tych sfer ma duży potenticjawdla wdrażania modelu zrównoważonego rozwoju。泽względu na fakt， że efektywne, tanie oraz proste - metovania surowców majei rosnące znaczenie w gospoderce o obiegu zamkniętym, 120 Kasina等。2022 / Gospodarka Surowcami矿物-矿产资源管理38(3)，105-120 bioługowanie metaljest metodoze, która obecnie cieszy siocoraz większym zainteresowaniem。玩笑到również处理istotny kontekście neutralizacji surowców odpadowych umożliwiającej ich bezpieczne magazynowania i zastosowanie。W . prozezadzonym . badaniu powszecie występujące细菌酸硫氧化硫硫杆菌，które szeczęsto używane W . procesach bioługowania ze względu na . fakt rich wysokiej tolerancji na metale ciężkie, zostały wykorzystane W . 28-dniowym ekspermencie。Sposób i zmienność wczasie, wjaki bakterie zasiedlajoasad po spalaniu, zostaowzao obserwowany, pzy荧光，jnej microskopii optycznej skaningwej microskopii elektronowej。Stężenie pierwiastków w osadach po spalaniu iw poreakcyjnych roztworach zostało zmierzone przy użyciu indukcyjnie sparowanej plazmowej光谱分析，a efektywność odzyskiwania pierwiastków została obliczona na podstawie uzyskanych wyników。Popioły po spalaniu odpadów komunalnych oraz popioły lotne ze spalania osadów ściekowych zostały ujęte w ekspermencie。Stosunki ekstrakcji pierwiastków były dalekie od zadowalających ze średnią 20 oraz 50% dla popiołów po spalaniu odpadów komunalnych oraz popiołu z osadów ściekowych。Pozyskane wyniki ski ski w zgodzie z obserwjami dokonanymi przy pomocy mikroskopii, gdzie相对于liczba bakterii wzrosła niewiele我们wspomnianym czasie w przypadku popiołów ściekowych i była w zasadzie niedostrzegalna w przypadku popiołów dennych。

Every social group exhibits a need to make decisions that are binding for all its members and the participation of various interest groups in decision-making today is an integral part of modern political and legal thought as well as administrative processes. Recently, increased community engagement and greater awareness of the society with regard to the possibility of influencing the development on a microregion (commune) scale have also been observed. This often translates into problems in obtaining a social license for a given project, which is particularly visible in mining activities. however, obtaining such a license requires the involvement and awareness of many stakeholder groups on which a project will have a direct impact. It should be ensured that this engagement takes place at a very early 28 Kot-Niewiadomska et al. 2022 / Gospodarka Surowcami Mineralnymi – Mineral Resources Management 38(4), 5–28 stage of a given project. In the case of mining activity, which is possible only after obtaining appropriate licenses (exploration or exploitation), this involvement takes the form of public consultation. This is due to the legal conditions presented in the following article for 3 EU countries (Poland, Austria, Sweden) and Serbia. The analysis showed that participation is mainly at the level of consultation in all countries and is an important element of the environmental impact assessment (EIA) procedure of the mining project, which is an important stage in obtaining a mining (less frequently exploration) license. Public consultations at the stage of spatial planning are also present and have a diverse scope. however, special attention should be paid to these as they are crucial for proper mineral deposit safeguarding.

Recently, increased community engagement and greater awareness of the society with regard to the possibility of influencing the development on a microregion (commune) scale have also been observed. This often translates into problems in obtaining a social license for a given project, which is particularly visible in mining activities. however, obtaining such a license requires the involvement and awareness of many stakeholder groups on which a project will have a direct impact. It should be ensured that this engagement takes place at a very early 28 Kot-Niewiadomska et al. 2022 / Gospodarka Surowcami Mineralnymi – Mineral Resources Management 38(4), 5–28 stage of a given project. In the case of mining activity, which is possible only after obtaining appropriate licenses (exploration or exploitation), this involvement takes the form of public consultation. This is due to the legal conditions presented in the following article for 3 EU countries (Poland, Austria, Sweden) and Serbia. The analysis showed that participation is mainly at the level of consultation in all countries and is an important element of the environmental impact assessment (EIA) procedure of the mining project, which is an important stage in obtaining a mining (less frequently exploration) license. Public consultations at the stage of spatial planning are also present and have a diverse scope. however, special attention should be paid to these as they are crucial for proper mineral deposit safeguarding.

The demand for energy on a global scale increases day by day. Unlike renewable energy sources, fossil fuels have limited reserves and meet most of the world’s energy needs despite their adverse environmental effects. This study presents a new forecast strategy, including an optimization-based S-curve approach for coal consumption in Turkey. for this approach, Genetic Algorithm (GA) and Particle Swarm Optimization (PSO), Grey Wolf Optimization (GWO), and Whale Optimization Algorithm (WOA) are among the meta-heuristic optimization techniques used to determine the optimum parameters of the S-curve. In addition, these algorithms and Artificial Neural Network (ANN) have also been used to estimate coal consumption. In evaluating coal consumption with ANN, energy and economic parameters such as installed capacity, gross generation, net electric consumption, import, export, and population energy are used for input parameters. In ANN modeling, the feed forward Multilayer Perceptron Network structure was used, and levenberg-Marquardt Back Propagation has used to perform network training. S-curves have been calculated using optimization, and their performance in predicting coal consumption has been evaluated statistically. The findings reveal that the optimization-based S-curve approach gives higher accuracy than ANN in solving the presented problem. The statistical results calculated by the GWO have higher accuracy than the PSO, WOA, and GA with R 2 = 0.9881, RE = 0.011, RMSE = 1.079, MAE = 1.3584, and STD = 1.5187. The novelty of this study, the presented methodology does not need more input parameters for analysis. Therefore, it can be easily used with high accuracy to estimate coal consumption within other countries with an increasing trend in coal consumption, such as Turkey.
全球范围内对能源的需求日益增加。与可再生能源不同，化石燃料储量有限，尽管对环境有不利影响，但仍能满足世界大部分能源需求。本研究提出了一种新的预测策略，包括基于优化的土耳其煤炭消费s曲线方法。对于该方法，遗传算法(GA)和粒子群优化(PSO)、灰狼优化(GWO)和鲸鱼优化算法(WOA)是用于确定s曲线最优参数的元启发式优化技术。此外，这些算法和人工神经网络(ANN)也被用于估算煤炭消耗。在用人工神经网络评估煤炭消费时，能源和经济参数，如装机容量、总发电量、净用电量、进口、出口和人口能源，被用作输入参数。在人工神经网络建模中，采用前馈多层感知器网络结构，并采用levenberg-Marquardt Back Propagation进行网络训练。利用最优化方法计算了s曲线，并对s曲线预测煤耗的性能进行了统计评价。结果表明，基于优化的s曲线方法比人工神经网络具有更高的求解精度。GWO计算的统计结果准确率高于PSO、WOA和GA, r2 = 0.9881, RE = 0.011, RMSE = 1.079, MAE = 1.3584, STD = 1.5187。本研究的新颖之处在于，所提出的方法不需要更多的输入参数进行分析。因此，它可以很容易地高精度地用于估计其他国家的煤炭消费量，这些国家的煤炭消费量呈增长趋势，例如土耳其。
