Предложенная модель позволяет визуализировать процессы разрушения среды при фильтрации газа в ней с последующим выбросом разрушенного массива. Получены картины образования куполов над дневной поверхностью и их разрушения в режиме реального времени. После выброса возникают воронки, которые сохраняют свою форму в случае смоченного песка благодаря прочности, возникающей за счет капиллярных сил. По результатам опытов определены геометрические параметры воронок в зависимости от глубины заложения источника газа.</p></abstract><trans-abstract xml:lang="en"><p>This article presents the results of experiments conducted on a two-dimensional optically transparent model, aimed at physically modeling a gas outburst in a loosely cohesive granular medium. The proposed model allows for visualization of the processes of gas destruction in the medium during gas filtration, followed by the release of the destroyed mass. Images of the formation of domes above the daylight surface and their destruction are obtained in real time. After the outburst, craters form, which retain their shape in the case of wet sand due to the strength generated by capillary forces. Based on the experimental results, the geometric parameters of the craters were determined depending on the depth of the gas source.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фильтрация газа</kwd><kwd>слабосвязная гранулированная среда</kwd><kwd>выброс газа</kwd><kwd>образование воронок.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas filtration</kwd><kwd>loosely cohesive granular medium</kwd><kwd>gas outburst</kwd><kwd>crater formation</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>проект Российского научного фонда No 22-67-00025; госзадание No 125012100531-7</funding-statement></funding-group></article-meta></front><body><p> </p></body><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
