Then the article analyses the effecting elements about the economic result of blasting and puts forward some improving measures, and summarizes optimizing model on economic result of blasting both internal and overseas bearing upon. the theory is based on the blasting cost model, which proposed by dr. zhong hanrong. combining with the specialties of water and electricity engineering, starting off through blasting result, it emphasizing considers drilling cost, deep hole bench blasting cost, reblasting cost, and the cost of bottom fleet hole blasting that in mixed loading emulsion explosive blasting
本文在加拿大鐘漢榮博士提出的爆破成本模型基礎上，結合水電工程的特點，從爆破效果出發，著重考慮了應用混裝乳化炸藥爆破的鉆孔成本、深孔梯段爆破成本、二次爆破成本和爆破后根底淺孔爆破成本，以塊度、振動、安全為約束條件，以這四項成本最小為目標函數，廣泛收集各種爆破經濟技術條件，建立了爆破優化經濟數學模型。 -
Taking bench shooting of the shuibuya yihongbao project as example, it makes use of the digital television system of drilling overall - hole wall to actually measure, the testing result of lateral fractural range is 4 - 5m, and that of bottom fractural range is about 3m
本文試驗工作是以水布埡溢洪道工程梯段爆破為實例，採用鉆孔全孔壁數字電視系統對混裝乳化炸藥爆破破裂范圍進行了實際測試，測試結果為：側向破裂范圍為4 5m ，底部破裂范圍值為3m 。 -
