新冶钢场平石方爆破
|
摘要
针对某钢厂复杂环境下的场平石方爆破工程,选取了合理的孔网参数和炸药单耗,采用了连续柱状装药和分层装药相结合的装药结构,设计了逐孔起爆和孔内外毫秒延期起爆相结合的爆破网路,从而有效地控制了爆破飞石和爆破振动危害,达到预期的工程目的。
Continuous columnar aim at the complex environment around the blasting of leveling site rock in a steel company,the reasonable blastholes space and specific charge is selected,and the charge structure of continuous columnar charge with layer charge is adopted,meanwhile the blast circuit of hole by hole firing with millisecond delay firing in and out hole is designed,which effectively controll the blast fly rocks and blasting vibration to achieve the desired results.
