| 不可预见费用又称预备费，在工程投资概〈估〉算中，预留为支付施工中可能发生的、比预期的更为不利的水文、天气、地质及其他社会、经济条件而需增加的费用，一般以总投资的某一百分数计 | contingency cost |
| 不用封泥的糊炮爆破 | mud without capping |
| 不用炮泥的糊炮二次爆破 | mudcapping without capping |
| 不用炸药的采矿环境 | explosive s-free mining environment |
| 不用讲稿的 | extemporaneous |
| 他们成功地采用了超声波技术把鱼赶走、有效避免爆破对珍贵鱼类和其他水生物的不利影响、因而体现了工程建设与生态保护的和谐 | They have successfully adopted ultrasonic technology to drive away fish, which effectively avoided the impact of blasting on such valuable fish and other aquatic organisms, thus reflecting the harmony of engineering construction and ecological protection |
| 使用电子延迟顺序可以增加5 - 10个百分点的抛掷量、且不必增加炸药能量或其他爆破投人 | An increased throw of the order of 5 - 10 percentage points may be obtained through the use of electronic delay sequences, without any increase in explosives energy or other blast inputs |
| 利用系数不高的炮孔组 | short round |
| 在炸药爆炸过程中、合成能量转化为破岩和位移这些有益的实用能量。振动、冲击波和飞石这些不利的负面效应也是由合成能量产生的 | In the detonation of explosives, the resultant energy is converted into beneficial applications such as fragmentation and displacement. It is also responsible for adverse side effects such as vibration, airblast and flyrock |
| 暂不能利用储量由于煤层厚度小、灰分高、水文地质条件及其他开采技术条件特别复杂等原因，目前开采有困难，暂时不能利用的储量。又称平衡表外储量 | useless reserves |
| 有安全意识的立法人员久久期盼不用炸药的采矿环境 | Safety conscious legislators have long held a vision of an explosives-free mining environment |
| 此外、明智的炸药用户还须知道不同的结构、公用设施、设备和用具对振动感度的变化、而且要记录爆破场地附近的情况 | Also, the explosives user would be wise to become aware of the variation in vibration sensitivities of different structures, utilities, facilities and materials, and to make note of the conditions near his operations |
| 炸药感度根据所受外界能量作用的不同、可分为冲击波感度、撞击感度、摩擦感度、静电感度、雷电感度或其他能量形式的感度 | The stimulus to which an explosive is exposed must be included in any reference to the sensitivity, whether shock, low-velocity impact, friction, electrostatic charge, lightning, or other source of energy |
| 然而、大规模减少单位炸药消耗量是不可取的、因为这样反倒影响破碎作用和排石量 | It is not recommended, however, to reduce the powder factor significantly because it will adversely affect the fragmentation and |
| 由于岩石破碎不理想、影响到开采计划的实施、进而影响到开采成本、常用的爆破破碎模型只能对破碎曲线进行粗略分析 | Current blast fragmentation models tend to focus on the coarse end of the fragmentation curve because of the impact of poor fragmentation on excavation performance, and hence excavation costs |
| 自然规律不以人的意志起作用 | The law of nature acts in ways independent of man's will |
| 这种炸药不用于工程爆破 | This kind of powder does not apply to industrial blasting |
| 通常用于爆破设计和破碎模型中的这些参数、都是静态的、而非动态性质、只不过在用于模型时经验因素弥补了这种反常 | The parameters that are generally used in blast design and fragmentation modeling are the static rather than the dynamic properties, but empirical factors used in the models compensate for this anomaly |
