At this stage, a detailed bibliometric analysis was carried out for the selected articles from four thematic groups for risk in mining industry from the last decade. Ninety-four articles from four analyzed areas were adopted for detailed analysis. Most publications were found for the keywords _\"risk assessment\"_, which together accounted for almost 80% of all the analyzed texts. The number of publications for each of the analyzed search terms was:  
* Two publications in the area of _risk decisions_,
* Five publications in the area of _risk analysis_,
* Fifteen publications in the area of _risk management_,
* Seventy-two publications in the area of _risk assessment_. The analysis of the authors' and scientific centers' origins allows us to state that most of the publications from the studied area come from China (32 articles), Australia (10 articles), the USA and Canada (7 articles each). The regions of origin of the authors of the analyzed publications are shown in Figure 4.  
The analyzed publications were limited in step 2 of the adopted methodology to those published during the last decade. The adopted limitation seems to be correct, as the verification of the years in which subsequent articles were published indicates a clearly growing trend from 2015. As shown in Figure 5, for the last five years, the annual number of publications has been above 10, while in previous years it did not exceed six articles per year. This suggests that the topic risk assessment and management in the mining sector is far from being exhausted, and its popularity among researchers is still rising. It is safe to say that further developments and unique studies regarding this field of knowledge will keep appearing in the near future. Articles concerning risks in the mining sector have appeared in many studies. The 94 publications under analysis have been published in a total of 45 journals, of which more than 70% include one article each. A detailed list of journals in which the analyzed research results were published is shown in Figure 6. The figure shows that only those scientific journals for which at least two articles from the analyzed 94 were identified. The largest number of publications appeared in the journal _Human and Ecological Risk Assessment_ (12 articles). Numerous publications can also be found in _Environmental Geochemistry and Health_ and _Environmental Monitoring and Assessment_ (nine articles in each journal). Such a large number of publications in these top three journals is mainly due to the fact that research

This is confirmed by the analysis of the review articles presented in Section 1, as well as by the list of thematic areas presented in Section 4. It should be noted, however, that the topic of risk in the mining sector is of interest not only to journals devoted to the mining sector or environmental issues. Some publications also appeared in safety journals (_Journal of Safety Research, Safety Science, Food Security, Journal of Loss Prevention in the Process Industries_), as well as those related to management and production research (_Production Planning and Control, Journal of Cleaner Production_). The detailed analysis that also contains the presentation of investigated papers according to the place of their publication is given in Appendix B, Table A2. The conducted biometric analysis also concerned the repeatability of the indicated keywords used in the papers (Figure 7). The highest share among repeated keywords has the phrase _risk assessment_,
