摘要(Abstract)：

鸡山石方工程在复杂环境下应用高梯段深孔光面爆破技术，既保证了周围环境安全，又达到了理想的爆破效果。文章较全面地介绍了光面爆破的设计、施工工艺及安全防护等方面的主要技术特点与经验，并通过理论研究提出光爆设计的主要计算公式，为在繁华城镇和重要设施附近进行大量石方控制爆破提供了技术依据，所采用的技术措施和施工工艺值得推广应用
The high level longhole smooth surface blastin technology used in Jishan Stonework project in complicated circumstances,ensures the surroundings safe and an ideal blasting result has been obtaind.In tihs paper,the design of Smooth blasting,construction technology and safety protection were introduced in detail.The main calculation formula of smooth blasting design was put forward through theoretical research.The technical basis has been given to controlled blasting of large scale of stonwork project mear main buildings in cities.The technical measures and construction technology mentioned above are valuable for promotion and application.
