Detonator is the crucial part of the cartridge booster train and is the necessary primer unit during the engineering blasting , so its output is one of the main properties of detonator 雷管是彈藥傳爆序列中重要的組成部分,也是工程爆破中必不可少的起爆元件,其輸出能力是雷管的重要性能之一。
Abstract : this paper discusses the vibration velocity of blasting seism and the reaction chart of the blasting vibration , and offers some helpful suggestions about solving engineering blasting problems 文摘:對爆破地震的振動速度與爆破振動反應(yīng)譜進行了分析和探討,為解決工程爆破問題提供了參考意見。
According to many engineering blasting cases , in - depth analysis of underwater blasting mechanics , and discussion about the advantages of touch - ground charging for underwater rubble - mound foundation explosive compaction , it is proved that touch - ground charging method for explosive compaction results in good effect and is characterized by simple and feasible operation , and low cost , and thus well accepted by clients and construction units 摘要通過大量的工程爆破實例,深入的水下爆炸機理分析以及觸地布藥方式在水下拋石基床爆炸密實優(yōu)越性的討論,充分表明采用觸地布藥方式實施爆炸密實的效果良好,操作簡單可行,節(jié)約工程成本,并得到了業(yè)主、施工單位的肯定和好評。
It studied the engineering geology condition of the heigou mine - field of jisco . by the abundance of basic data with investigates and lab experiments , it estimated and analyzed the stability of the side slope of the heigou mine - field with many research methods that included " the ultimate balance " , " the discrete cell " and " the fea " . besides these , it gave same advice about analogous engineering in order to offer certain evidence for the later management of heigou mine - field and for the engineering blasting design 本文以工程地質(zhì)學、巖石力學理論為基礎(chǔ),針對黑溝礦區(qū)工業(yè)場地邊坡特殊的工程地質(zhì)條件進行研究,在通過現(xiàn)場調(diào)查、實驗室試驗等手段獲得大量基礎(chǔ)資料的前提下,對黑溝礦區(qū)工業(yè)場地的邊坡,采用極限平衡法、離散單元法、三維彈性有限元法等多種方法進行了穩(wěn)定性評價及分析,并提出了相應(yīng)的工程措施建議,為今后黑溝礦區(qū)工業(yè)場地邊坡管理及大爆破設(shè)計等提供了一定的依據(jù)。
