The technique of slope protection of deep and wide road cut of two side by chamber blasting;

The paper gives out main technical measures to keep side-slope in stableness by chamber blasting,which can also make high side-slope stable only when useful geological information and reasonable plan are well known,and charge's broken scope is precisely defined and single charge is independently exploded.

To study force characteristics of pre-stressed anchor (freestyle, full-length bond-type and semi-full bond-type) in the antiknock chamber effected by concentrated explosive charge, the geo-mechanical model for researching antiknock properties of the anchor chamber in the "Test device of geotechnical engineering antiknock structure model" is tested.

Based upon practical observation data, this paper deals with damage effects of deep rock openings under blast stress wave with diversified loads, layouts and geological media.

Dynamic failure of deep-buried rock openings under explosion stress wave is very important in the design and analysis of anti-explosion and anti-vibration engineering.
