Сущность обобщенного критерия основана на сочетании временного изменения экономической эффективности траншеекопателей в процессе разработки мерзлых грунтов или горных пород с критериями наступления предельного состояния резцов. Показано существование оптимального времени замены резцов по критерию минимума стоимости погонного метра разработанной траншеи для различных видов временных зависимостей производительности траншеекопателей. Рассмотрены особенности критериев предельного состояния резцов. Даны рекомендации по комплектованию траншеекопателей информационными устройствами, что позволит избежать неоднозначности в определении момента времени для смены комплекта изношенных резцов.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the generalized criterion for timeliness of cutting tool replacement in chain trenchers. The generalized criterion is based on a combination of the time change of the economic efficiency of chain trenchers during the frozen soil excavation having the limit state criterions for the cutters. The optimum time is shown for the cutting tool replacement using the criterion of minimum cost per running meter of a developed trench for different types of time dependencies of trencher performance. The limit state criteria are considered for cutting tools. Recommendations are given to trencher equipment with information devices to avoid ambiguity in ascertaining the time for cutter replacement.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цепные траншеекопатели</kwd><kwd>предельное состояние</kwd><kwd>резцы</kwd><kwd>своевременность замены</kwd><kwd>эффективность</kwd><kwd>оптимальное время</kwd><kwd>ladder ditcher</kwd><kwd>limit state</kwd><kwd>cutters</kwd><kwd>timeliness of replacement</kwd><kwd>efficiency</kwd><kwd>optimum time</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">French, H.M.
