丽水市上沙溪埋管段进口浅孔控制爆破技术

Short-hole Blast Controlling Techniques in Embedded-pipe Inlet in Shangshaxi

在周边环境复杂的条件下,采用浅孔控制爆破技术,合理确定浅孔控制爆破各项技术参数和有效地控制爆破中产生的有害效应,对于保证施工和周边安全、获得理想的工程效果.就丽水市上沙溪埋管进口石方开挖浅孔控制爆破技术进行了论述.

It is very important to determine the technique parameters ,and to control the side-effects in short-hole blasting under unfavor- able surroundings, so as to ensure constructing safety and ideal quality. The short-hole blast controlling techniques in embedded-pipe in- let section is illustrated taking Shangshaxi in Lishui for example.
