复杂环境下危石的爆破处理

Dangerous Rock Treatment by Blasting in Complex Environment

针对危石周边环境复杂环境的特点,提出了用弱松动浅孔控制爆破来进行处理的方案。为防止飞石和危石解体后的小块石滚落山下伤及人员,采用了在危石正前方设立挡墙、胶皮网进行覆盖,选择合理的爆破参数及分层处理等措施;为防止在施工过程中危石滑落,采用木料支撑和锚杆暂时固定,确保了危石安全、快速的清除。

According to the complex surrounding around dangerous rock, we proposed to use the weak loose short-hole controlled blasting was proposed as treat program. For preventing the fly rock and the crisis after the disin- tegration rolled down the mountain and injured personnel, the retaining wall in front of the dangerous rock, rubber network for coverage, the blasting parameters and reasonable measures such as hierarchical processing were used;For preventing dangerous rock fall during construction, wood support and rock bolting were used to temporarily fixed, to ensure the safe of dangerous rock and quick clearance.
