The aim of the study is to substantiate the parameters of drilling and blasting drivage of horizontal and inclined (up to 12o) mine workings on the basis of high-performance self-propelled equipment and new designs of box cuts with cleaning explosive charges (0.2 kg of 6ZhV ammonite), placed in advance holes of 65 to 105 mm in diameter. The paper presents the results of the analysis of practical experience and scientific achievements in the field of drilling-andblasting rupture of solid media and continuum mechanics. The need for new designs of box cuts, reliability of which in the formation of high-quality (clean) cut cavity reaches 0.95-1.00, was substantiated. New design options of box cuts have been developed, the peculiarity of which consists in provision of sufficient compensation (peripheral) volume with the use of blast hole cut charges for blasting rupture of trapezoidal partitions, with the compensation volume factor of 2.50 to 1.34. Promising areas of research were shown using the example of complicated structure ore deposits and large faults in the Kirovograd ore district and crystalline rocks of the Ukrainian shield at the following mines of Ukraine: PJSC KZhRK, CJSC Sukhaya Balka (Kryvyi Rih), Vostok-Ruda LLC, SE VostGOK (Zheltye Vody), CJSC ZZhRK, etc. Promising areas of research were proposed using the example of complicated structure ore deposits typically formed at the junction of large faults; besides, the use of environmentally friendly emulsion explosives and self-propelled emulsion explosive chargers was recommended.</p></abstract><trans-abstract xml:lang="ru"><p>Наиболее сложными и трудоемкими в добыче полезного ископаемого, требующими постоянного изучения и совершенствования технологии и технических средств для ее осуществления являются буровзрывные работы (БВР). Целью исследования является обоснование параметров буровзрывной проходки горизонтальных и наклонных (до 12º) горных выработок на базе высокопроизводительного самоходного оборудования и новых конструкций призматических врубов с подчищающими зарядами взрывчатых веществ (ВВ) по 0,2 кг аммонита марки 6ЖВ, размещенных в опережающих скважинах диаметров от 65 до 105 мм. В работе представлены результаты анализа практического опыта и научных достижений в области буровзрывного разрушения твердых сред, механики сплошных сред. Обоснована потребность в новых конструкциях призматических врубов, надежность работы которых по образованию качественной (чистой) врубовой полости достигает 0,95–1,00. Рекомендованы варианты новых конструкций призматических врубов, особенность которых заключается в обеспечении каждой из них достаточным компенсационным объемом для работы шпуровых врубовых зарядов ВВ на разрушение трапециевидных перегородок с коэффициентом компенсационного объема от 2,50 до 1,34. Показаны перспективные направления исследований на примере рудных месторождений сложного строения и мощных тектонических разломов Кировоградского рудного района и кристаллических породах Украинского щита на шахтах Украины: ПАО «КЖРК», ЧАО «Сухая Балка» (г. Кривой Рог), ООО «Восток-Руда», ГП «ВостГОК» (г. Желтые Воды), ЧАО «ЗЖРК» и др. Предложены перспективные направления исследований на примере рудных месторождений сложного строения с типичными образованиями в узлах сочленения мощных тектонических разломов и применения экологически чистых эмульсионных ВВ, а также самоходных зарядчиков эмульсионных ВВ.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рудные массивы</kwd><kwd>горные выработки</kwd><kwd>буровзрывная проходка</kwd><kwd>призматические врубы</kwd><kwd>подчищающий заряд</kwd><kwd>безопасность</kwd><kwd>эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ore mass</kwd><kwd>mine workings</kwd><kwd>drivage with blasting technique</kwd><kwd>box cut</kwd><kwd>cleaning charge</kwd><kwd>safety</kwd><kwd>performance</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">Jonson D.
