大连石灰石矿与中国科学院矿冶研究所合作自1964年试验毫秒爆破以来,进行了多次的毫秒爆破,对减弱爆破震动的试验,取得了显著效果。西山采区爆破对周围重大建筑物地震动影响,是一个生产关键问题,不仅对附近市变电所及净水车间的正常生产有威胁,而且也限制了矿山生产的发展。几年来随着矿山生产的不断发展,这个矛盾也就愈突 Since the cooperation between Dalian Limestone Mine and the Institute of Mining and Metallurgy, Chinese Academy of Sciences, has conducted many millisecond blasting tests since the blasting in milliseconds in 1964 and achieved remarkable results in reducing the blasting vibration test. The impact of blasting in Xishan mining area on the ground motion of major buildings around it is a key production issue, which not only threatens the normal production of nearby municipal substations and water purification plants, but also limits the development of mine production. Over the years with the continuous development of mine production, the contradiction will be more pronounced
