Crossing Military Facility Shallow-buried Tunnel Micro Vibration Blasting Construction Technology

One of the key problems in the micro vibration blasting technology construction of shallow buried mountain tunnel is to ensure the safety and progress of the whole project construction, especially when the shallow buried mountain tunnel cross militaryinstallations, which raises higher request on micro vibration blasting construction. It is an important issue for tunnel construction to achieve the ideal blasting effect under the premise of controlling the blasting vibration safety speed. Combined with engineering examples, from theselection of blasting parameters, the control of design and monitoring, etc, and constant scheme optimization, finally the safe and effective design scheme and construction method are put forward, the successful experience is summarized, and good effect is achieved. It is of certain referential value for construction of similar projects.
