为了减少索赔事件的发生、炸药的使用人员保存完整的爆破作业记录是聪明的举措、监测爆破振动和冲击波、尽可能通知公众、尽量降低钻孔和交通噪声、减少粉尘并减小其他可觉察到的影响 | In order to reduce damage claims, the explosives user is wise to keep complete records of his operations, to monitor vibrations and airblast, to do what he can to inform the public, and to minimize drilling noise,dust,traffic noise, and other perceptible effects |
以降调唱或奏 | flat |

冷却水降温法这种方法是在炮孔中插人一根一端封闭的导管〈叫外筒〉把一根特制的水冷爆破筒〈叫内筒〉插人外筒中,往水冷爆破筒中通水冷却,然后起爆 | reducing temperature with cooling water |
化学反应速率取决于压力的大小、并随着反应物质的膨胀而迅速降低 | The rate of chemical reaction is strongly pressure dependent and will decrease rapidly as the reacting material expands |
反常下降指数 | abnormal descent index |
地基沉降地基土层在附加应力作用下压密而引起的地基表面下沉 | settlement of foundation |
均匀沉降基础底面〈地基表面〉上各部位下沉量均相等的地基沉降 | uniform settlement |
将伤亡的风险降到最小 | minimizing of the risk of death or injury |
尤指降半音 | flat |
应力降岩土破坏后,应力由峰值降为残余值的过程〈或峰、残强度的差值〉 | stress drop |
应力降低区岩体内由于采掘工程影响引起应力重新分布后而形成的低于原岩应力的区域 | stress-released zone |

改进后的爆破技术可对降低矿山温室气体排放的总强度做出巨大贡献. | improved blasting can make a significant contribution to reducing the overall intensity of GHG emissions from mines |
抽水后水位降低 | drawdown |
水位降低量 | drawdown |
然而、制造炸药使用生物燃料代替化石燃料的结果、会使二氧化碳的整体排量降低、因为生物燃料在生长期从大气中消除同样当量的二氧化碳 | However, the use of biofuels instead of fossil fuels in explosives would result in lower overall CO₂ emissions, as the biofuel growth phase removes an equivalent amount of CO₂ from the atmosphere |
煤炭采收改进技术相应地降低矿山温室气体排放强度 | The improved coal recovery translates to a corresponding decrease in mine GHG emissions intensity |
爆破成本降低 | reduced blasting cost |
爆速降低 | detonation velocity reduction |
爆速升降带爆速梯度沿其炮孔长度而变〈上升或下降〉。产生升降带的一个原因可能是炸药的爆速不同于起爆药的爆速。在大型炮孔中,爆速可能由于起爆药至冲击波达到炮孔壁之间的距离而下降,然后稳定、再提速 | run-up or down zone |
由于有降低成本的需要、重视矿工的健康和安全的问题以及随着毕业生技术水平的日渐提高、导致我们在20世纪的80年代末和90年代初越来越关注炸药技术的应用 | An ongoing need to reduce costs, and an increasing emphasis on the health and safety of mineworkers,together with the growing influence of technically skilled graduates resulted in increased attention being paid to explosives technologies during the late eighties and early nineties of the previous century |
由于膨胀气体挤压这种物质、致使能量损失速度快、爆后产物的压力和温度迅速下降。这些损失作为膨胀波传到反应区之内、因而降低了压力和反应速率、且最终消除了对爆震波面传播的能量支持 | As the expanding gases compress such material, energy is lost rapidly and pressure and temperature drop sharply in the reaction products. These losses are communicated to the interior of the reaction zone as a rarefaction wave, lowering the pressure and reaction rate, and ultimately removing support far the propagation of the detonation front |
由于造价降低幅度大、用震动管代替装有雷管的导火线点火索则名正言顺 | Costs fell to a level which made it justifiable to replace capped fuse-igniter cords with shock tubes |
瞬时沉降荷载作用瞬间所产生的地基沉降 | immediate settlement |
瞬时沉降荷载作用瞬间所产生的地基沉降 | instantaneous settlement |
研究表明、与同样装药重量的裸露爆破相比、这样的爆破可使压力波释放威力降低90%以上 | Studies have shown that such blasts have a greater than 90% diminution in the strength of the pressure wave released, compared with unconfined blasts of the same charge weight |
这些技术在世界几个地方正在现场改进、并将大大降低炸药厂温室气体排放的总量 | R-of these technologies are underway at several sites around the world and will achieve massive reductions in overall GHG emissions of explosive manufacturers |
这些考虑的事项也突出表明、爆破界通过改进爆破结果来降低温室气体排放量是其主要目标 | Such consideration also highlights the major targets for the blasting community to reduce GHG emissions through improved blast outcomes |
通常在进行爆破方案设计时希望使抛掷量最大化。但是、在一些情况下并不需要达到最大抛掷量。例如当达到最大抛掷量会使得吊铲达不到最佳的工作高度时、反而造成爆后利润的降低 | Usually cast blast design involves maximizing the castover. However, in other situations less than maximum cast may be desired. This can occur far example if the after blast profile from maximum casting would lower the dragline elevation to the point where the machine has inadequate stacking height |
