The authors’ attention is focused here on presenting the essence of payment gridlocks, their consequences, as well as the causes on the sides of both the debtor and the creditor. In the empirical part of the article, the authors focused on assessing the problem of payment backlogs in selected mining and energy-production companies in Poland. A study on selected companies from this industry was conducted, the purpose of which was to show the scale of delayed payments with the particular identification of those that are payment backlogs (i.e. a delay of at least 60 days). Five major companies from the energy industry in Poland were selected for the study, representing both the mining and energy production sectors. These companies are Polska Grupa Górnicza SA, Jastrzębska Spółka Węglowa SA, ENEA SA, Energa SA and TAURON Polska Energia SA According to the available data, payment terms in this sector are the longest in the European Union compared to other sectors of the economy. In Poland, the situation is no different in this respect. This is especially visible in the mining industry, which is perceived as very risky when it comes to timely payments. Undoubtedly, reducing payment gridlocks in this industry is a difficult task, which results from its specificity and the number of problems it is struggling with, which have been additionally reinforced by the Covid-19 pandemic. © 2022.

The process of screen blocking involves grains of varying size being blocked in sieve holes. this is a phenomenon that significantly decreases the screening process capacity. the screen blocking coefficient f is applied for a description of screen blocking. Blocking grains are the ones which is equal to or slightly larger than the sieve holes. Those grains do not pass through the sieve holes, remain over the sieve and may clog (block) the sieve holes, thus reducing the screen clearance coefficient. the tests were done using a laboratory vibrator and control sieves, by subsequently screening mixtures of particulate materials with a different content of blocking grains and different percentage share of the upperand lower-size fractions. Particulate materials of three model grain shapes were used for the tests: spherical, sharp-edged and irregular. The paper also includes a statistical analysis of the results obtained through experiments and an innovative method for describing sieve holes blocking. the new blocking coefficient specifies the percentage number of blocked sieve holes in relation to the total number of sieve holes. grain size is a parameter that determines the value of the screen blocking coefficient in time. an increase in the content of blocking grains in the mixtures results in an increase in the percentage number of blocked sieve holes. the content of individual fractions in the mixture also has a significant impact on the course of sieve holes blocking. screening is a very common industrial practice, and various designs of screens and types of sieves are available. that is why the subject of this paper is so important.","PeriodicalId":50416,"journal":{"name":"Gospodarka Surowcami Mineralnymi-Mineral Resources Management","volume":"27 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86449247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Loss of profits occurring due to the halting of mining operations arising from occupational accidents or reasons related to legislation","authors":"Taşkın Yıldız","doi":"10.24425/gsm.2021.139739","DOIUrl":"https://doi.org/10.24425/gsm.2021.139739","url":null,"abstract":"In the event of occupational accidents in mining, investors can calculate approximately how much loss will be incurred at the time of the accident. However, in halting mining as a result of occupational accidents or legislation, investors, will perhaps not care about how much of a loss to profits will arise due to the resulting downtime of mining operations. The reason for this is that there is no such halting in mining operation as yet and mining activity is continued. Avoiding halting mines due to occupational accidents and legislation would enable the prevention of unexpected costs resulting from these time losses. The aim of this study was to find out how much the loss of profits resulting from the downtime of mining enterprises due to the aforementioned reasons are in total, and how much the ratio of loss of profits to annual operating costs is on average on an annual basis. To determine the loss of profits and to minimize the accidents in enterprises, permanent supervisors, who are assigned in the enterprises where they are working, were given a survey through the SurveyMonkey program. Of the 235 permanent supervisors who filled out the survey on behalf of the mining enterprises, 58 answered all of the multiple-choice questions examined in the study. These questions were analyzed together according to different mineral groups and differences in mining operation methods. As a result of the analysis, it was determined that the annual loss of profits of mining enterprises resulting from the aforementioned periods of downtime, and the ratio of these values to the annual operating costs constitute a rather significant share. The aim of the article was to raise awareness to have mining companies appropriate more funds for occupational health and safety.

The resource utilization rate and the consumption of hot water per ton of sulphur are the main criteria of mining effectiveness. They depend on the porosity and permeability of the rocks forming the deposit, the content and mode of occurrence of sulphur (ore texture), and the distribution of rocks with these varying features. Good recognition of geological and hydrogeological deposit features, exploitation results, is important for formulating the rules of controlling the course of exploitation in 77 Sermet et al. 2021 / Gospodarka Surowcami Mineralnymi – Mineral Resources Management 37(4), 55–78 order to achieve the best recovery of sulphur with the lowest possible water consumption and to reduce operating costs. Sulphur deposits are characterized by great local and directional variations in their structure and hydrogeological parameters. This makes the melting process irregular. The flow of hot water and melted sulphur is facilitated in certain directions. As a result, the shape, and distribution and form of exploited parts of the deposit are highly variable. Full information about the deposit is necessary for the proper understanding and prediction of processes that occur in the deposit during sulphur melting, for forecasting its effects, and for controlling the exploitation process. This information is obtained through the lithological description of core samples from exploratory and exploitation boreholes, geophysical borehole logging, and surface seismic surveys.
