      <abstract xml:lang="ru">
        <p>Приведены результаты сравнительных натурных испытаний промышленных взрывчатых веществ: гельпора ГП-2, граммонита 79/21 и аммонита № 6 ЖВ. Сравнение проводилось по параметрам воздушной ударной волны, образующейся при взрыве одинаковых по массе сосредоточенных зарядов гельпора, граммонита и аммонита.</p>

        <p>The results of comparative full-scale tests of industrial explosives: gelpor GP-2, grammonite 79/21 and ammonite No. 6 ZhV are presented. The comparison was carried out according to the parameters of the air shock wave formed during the explosion of similar mass of concentrated charges of gelpor, grammonite and ammonite.</p>
