前言光面爆破是五十年代初期在瑞典发展起来的一种新的爆破技术,它既能防止开挖边界以外围岩的超挖,得到平整的爆面,又能较好地保护围岩,减少支护经费,所以在国外很快得到推广,加拿大、美国和日本将之用于水利、地下厂房和露天采矿等爆破工程中,对提高工程质量起到了良好的作用。随着锚喷支护的发展,该项技术又被用在采矿 Preface Glossy blasting is a new blasting technology developed in Sweden in the early 1950s. It not only prevents over-excavation of surrounding rock outside the excavation boundary, obtains a smooth surface, but also protects the surrounding rock well. Therefore, it was quickly promoted abroad. Canada, the United States and Japan have used it in blasting projects such as water conservancy, underground factories and surface mining and played a good role in improving project quality. With the development of anchor spray support, the technology has been used in mining
