Шпуровое разрушение горных пород и бетона

Шпуровое разрушение горных пород и бетона

Abstract

The authors have studied the processes of blast-hole destruction of rocks and concrete using the polyethylene elecrtoexplosive cartridge. The article introduces the results of the laboratory current and voltage measurements. The resistances of the discharge channel and energy release dynamics in it at discharge initiation by exploding conductor both in water and polyethylene capillary have been calculated. It is ascertained that energy release in capillary discharge channel at the first current semioscillation is by ~15 % higher than in the discharge channel in water. It is shown that at stored energy in capacitive storage ~30 kJ the electric discharge destruction of samples with the size to 100×60×60 cm occurs.

Исследованы процессы шпурового разрушения горных пород и бетона с использованием электровзрывного полиэтиленового картриджа. Приведены результаты лабораторных измерений тока, напряжения; произведен расчет сопротивления канала разряда и динамики энерговыделения в нем при инициировании разряда взрывающимся проводником как в воде, так и в полиэтиленовом капилляре. Установлено, что в канале капиллярного разряда выделение энергии в первый полупериод колебаний тока на ~15 % выше, чем в канале разряда в воде. Показано, что при запасенной энергии в емкостном накопителе ~30 кДж происходит электроразрядное разрушение образцов размером до 100×60×60 см.
