1 制定大爆破安全规程的必要性 建国后,大爆破技术在我国迅速发展,在采矿、水电、交通、铁道等行业被广泛应用。1956年,在西北地区成功地进行了我国第一次药量为万吨级的露天剥离大爆破。1971年,在西南地区成功地进行了总装药量为10162.22t的露天大爆破,爆破方量为114×10~7m~3。近40年,我国成功地进行了60余次定向爆破筑坝。1960年,广东南水水电站定向爆破筑坝,总装药量1394t,上坝方量105
1, the need to develop a large blast safety regulations After the founding of the PRC, the rapid development of large-scale blasting technology in China, mining, utilities, transportation, railways and other industries are widely used. In 1956, the first large-scale open-air stripping explosion in China with a dosage of 10,000 tons was successfully carried out in the northwest of China. In 1971, a large open-air blasting with a total installed capacity of 10,162.22t was successfully carried out in the southwestern area with a blast volume of 114 × 10 ~ 7m ~ 3. In the past 40 years, more than 60 directional blasting dams have been successfully built in our country. In 1960, Guangdong Nanshui Hydropower Station directional blasting dam, the total installed capacity of 1394t, the dam on the amount of 105
