The article presents an analysis of renderings of the Swedish –s passive voice construction in a sample of multiple non-professional Polish translations of the same non-literary Swedish text, with a view to verify the validity of the thesis that translators resort to the minimax strategy while translating, as well as it discusses the possible correlation of this strategy with the development of characteristic features of the language of translation, the so-called “third code”. The article is structured as follows: Firstly, it presents the origin of the notion of the minimax strategy in translation studies and discusses it in reference to the psychology of translation. What follows is a brief description of the “third code” and its characteristic features. The subsequent part offers a discussion of the passive voice structures in Swedish and Polish as well as the semantically akin Polish constructions that may potentially be used to render the Swedish –s passive conceptualisations. Subsequently, the collected data are examined to answer the research questions. The article concludes with suggestions for further research on the “third code” and translation universals with reference to the minimax strategy.

Mining-induced sinkholes are a common feature in underground mines. Sinkholes usually disrupt mining operations and associated infrastructure when they occur. This paper presents a case study of the Lubambe copper mine, where nine (9) sinkholes have been reported on the eastern and southern limbs. The development of sinkholes has resulted in increased mining costs due to the closure of the 182 mL decline on the eastern limb and the 175 mL truck route on the southern limb. This study establishes the influence that poor ground formation, rock stability, geological structures, and inappropriate mining practices have on the formation of surface sinkholes. Assessment of ground condition was done by core logging, and borehole analysis was conducted using GEM4D-BasRock software to classify the rock mass quality based on RQD, RMR, Q-System and GIS. Assessment of the mining operational environment was focused on the effects of varying stope designs and sequencing on ground stability. Results of the study indicate that the formation of surface-induced sinkholes is attributed to historical mining in weak rock formation and weathered rock coupled with subsequent failure of unsupported stopes with stope height between 8 and 25 metres and less stand-up time of 7 days.
