摘要(Abstract)：

在“刘伯坚广场”爆破施工过程中,采用了浅孔小台阶微差松动控制爆破方法,结合微震动控制爆破技术和严密的安全防护措施,在复杂环境下,成功地完成5万多土石方的控爆施工。
In the construction of blasting engineering in Liubojian Square Project,small-bench,short-hole and millisecond loose controlled blasting were adopted.Over 50000m³ of rock was blasted successfully in complicated surroundings contributed to the use of strict protective measures regarding the micro vibration blasting technique.
