Abstract

Способ взрыва горных пород, в котором взрывные скважины подрывают по рядам с коротким межскважинным интервалом замедления, варьирующимся от 0,1 до 4,5 мс, таким образом, что поле напряжения распространяется внутри поля напряжения, предварительно распространившегося из предыдущей соседней взрывной скважины, таким образом усиливая разрушение и предотвращая высвобождение энергии взрыва в выпуск детонационного газа и воздействие на окружающую среду, вызванное выработкой излишнего звука. Короткий межскважинный интервал замедления получают при помощи длины ударной трубки, которая является необходимой для передачи сигналов инициирования во взрывные скважины, и используется в неэлектрических двунаправленных системах взрывания, таких как система PULKKOT. Сама ударная трубка представляет собой точное средство взрывания и замедления, которое может обеспечить короткий интервал замедления при наименьшей себестоимости производства, предотвратить огромный экономический ущерб из-за использования детонаторов замедленного действия с межскважинными замедлениями в 9, 17, 25 и 42 мс, и увеличить воздействие энергии взрыва более чем в 1,5 раза. Короткий межскважинный интервал замедления можно также обеспечить путем управления электронной системой инициирования, но в этом случае стоимость будет выше более, чем в 5 раз. Настоящее изобретение основано на более чем 50-летнем производственном опыте и используется в технике взрывных работ более 20 лет.A rock blasting method in which blast holes are undermined over rows with a short interwell interval of deceleration, varying from 0.1 to 4.5 ms, so that the voltage field propagates inside the stress field previously propagated from the previous neighboring explosive well, thus enhancing destruction and preventing the release of explosion energy into the release of detonation gas and the environmental impact caused by the production of excessive sound. The short wellbore interval is obtained using the length of the shock tube, which is necessary for transmitting initiation signals to blast holes, and is used in non-electric bidirectional blasting systems, such as the PULKKOT system. The shock tube itself is an accurate means of blasting and retarding, which can provide a short retardation interval at the lowest production cost, prevent enormous economic damage due to the use of time-delay detonators with interwell-down retardations of 9, 17, 25 and 42 ms, and increase the energy explosion more than 1.5 times. A short interwell interval of deceleration can also be achieved by controlling the electronic initiation system, but in this case the cost will be more than 5 times higher. The present invention is based on more than 50 years of production experience and has been used in blasting technology for over 20 years.
