摘要(Abstract)：

三山岛金矿将点柱式微拱形光面爆破技术运用于井下采场回采,减小了爆破对采场预控顶板的破坏,从而保证采场顶板的稳定。点柱式微拱形光面爆破采矿技术不仅达到安全回采的目的,而且取得了较好的经济效益,通过实践证明该方法在采场控顶方面具有较强的可操作性和实用性。
At Sanshandao gold deposit,the pointed pillar micro arched smooth blasting technology was used in underground stope to reduce the roof damage caused by blasting so as to ensure the stability of the stope roof.This technology not only reached the purpose of safe mining,but also achieved good economic benefits.The practice of the project has demonstrated that the technology is operational and practical in controlling the damage of the stope roof.
