摘　　要：温州电厂三期工程循环泵房进水口岩塞爆破其周边环境复杂,如何确保本工程在实施过程中,避免对已建的一、二期工程及其周围民房产生不利影响,如何保证岩塞爆破后,取水口过水断面满足设计要求,这是本工程要解决的重点问题。本文介绍了岩塞爆破开口尺寸与形状、爆破方案设计、爆破参数计算,以及岩塞爆破施工等技术问题。本次岩塞爆破非常成功。The water inlet rock stopper of the circulation pump house in the 3rd Stage Project of Wenzhou Power Plant was located in complicated environment. So how to ensure the blasting safety and avoiding adverse effect on the lst,2nd Stage Project and its surrounding private residence in the process, and how to guarantee the intake water cross section satisfying the design request after the rock stopper blasting, became the key problems to be solved. In this article,such detail technical problems as the hole size and shape of rock stopper blasting, the design of blasting scheme, the blasting parameter calculation and the execution of rock stopper blasting were introduced. The rock stopper blasting was a great success.
