Published: April 24, 2024

Introduction: The research concerns how making cut cavities improves drilling and blasting operations as well the optimum parameters to arrange both snubber auxiliary blastholes. Methods: methods include experimental industrial activities identify depth of first-section blastholes relative second-section It also identifies while driving mine workings ore breaking in stopes with different working sections rock mass strengths broken using technique cut-cavity formation. Results Discussion: Experimental explosions executed a production environment have proved efficiency proposed sectional formation cavity, which helped increase blasthole use coefficient (BUC) from 0.88 0.97. boreholes should be determined length strength. higher strength formation, larger ratio between first lengths be. results indicate that varies 0.5 more boreholes, depending upon latter If is 12 on Protodyakonov scale, increases 1.6 m 2.6 m, then increased 0.9 1.54 so 0.55–0.56 second section length. 18, 1.8 2.82 1.75 being 0.5–0.62 Applying novel procedure for will reduce cost operations. Moreover, may practical underground within stopes.

Kazakhstan’s image suffered due violent crackdown on protests during accusations supporting circumvent sanctions, government denies. However, awakened wave foreign interest Kazakhstan, gradually subsided over time. unearthed peak positive coincided such scientific achievements, cultural successes progressive changes, while decline characterized coverage problems within facing serious challenges, including worker safety issues, political suppression, economic instability questions about legitimacy elections. Resultantly, rather ambivalent portrayal emerged.

Introduction. The relevance is due to the fact that very little attention paid this topic in domestic papers despite importance of reserving budget funds as an instrument countercyclical policy and sustainability regional development. purpose study identify peculiarities reserve regulation constituent entities Russian Federation, which will allow a better understanding motivation incentives authorities their risk management activities. Materials Methods. With help general scientific methods analysis laws on fund process profile governmental resolutions for each subject Federation was carried out, original database main features at level Russia created. This made it possible systematize disparate information various aspects reserves regions, highlight common – step towards improving institution ensure financial stability. Results. differences between public legal entity (funds) executive authority are identified. It has been established provided by legislation not more than half regions while operates every subject. sources are, rule, sharp increase tax non-tax revenues during year balance accounts beginning year. Areas expenditures from usually limited universal, but depending conditions particular region they can be diverse. Discussion Conclusion. remains unpopular instrument.
