Include the following several respects basically : ( 1 ) according to blast dynamics theory , research calculate gather can powder bag cut base rock form in the range of the crack when blowing up individually , analyse that proving can gathers the function of cutting the rock of powder bag 基本包括以下幾個方面: ( 1 )根據爆破動力學理論,研究計算了單個聚能藥包爆破時切割基巖形成裂縫的范圍,分析論證聚能藥包切割巖石的作用。
( 2 ) use finite element analytical method , go on and gather can powder bag invade and cut to blow up simulation number value calculate rock , analyse in conformity with development of reeb , propagate , decay course , can blow up and down base rock characteristic of the stress go on research gathering , have proved that can gathers the result of cutting the rock of powder bag ( 2 )運用有限元分析方法,進行了聚能藥包侵切巖石的爆破模擬數值計算,分析了應力波的發展、傳播、衰減過程,對聚能爆破下基巖內部應力的特性進行了研究,驗證了聚能藥包切割巖石的效果。
