南湾水库除险加固二期溢洪道工程土石方开挖中,石方爆破施工区附近爆破环境较复杂,为了确保周围建筑和人身安全,把爆破振动、飞石、冲击波、噪音的影响减少到最小范围,必须制定合理的爆破方案,并且建立可靠的安全措施。 During the excavation of earth and stone in the second phase of spillway project in Nanwan Reservoir, the blasting environment near the stone blasting construction area is complex. In order to ensure the safety of surrounding buildings and people, the impact of blasting vibration, flying stones, shock waves and noise is reduced to a minimum extent , A reasonable blasting program must be established and reliable safety measures must be established.
