| 地质的影响 | effects of geology |
| 岩石完好度的地质测定 | geological diagnosis of rock grade |
| 岩石的地质学特性 | rock geotechnical properties |
| 当药包与自由面区域内的主要地质结构交叉或接近软弱面时、发生自由面破裂现象 | F-bursting occurs when explosive charges intersect or are in close proximity to major geological structures or zones of weakness in the face region |
| 振动持续时间是爆破设计、距离和地质学这三者的函数 | The vibration duration is a junction of blast design,distance and geology |
| 最重要的地质条件 | overriding geologic factors |
| 未知的地质条件 | unknown geological conditions |
| 然而、爆破所用炸药的特性、岩石类型或地质构造的物理特性或爆破定时起爆顺序及由于这些因素的微妙差别所产生的相互影响均要考虑 | There is no simple way, however, to take into account the interactions resulting from subtle differences in the characteristics of the explosives the blaster had at his disposal, the physical characteristics of specific rock types or geological formations, or the effect of the changes in timing of the initiation sequence on his blast |
| 爆破中所用的炮泥类型和分量以及对阶梯地形的处理、会大大地影响抛向空中的物质的多寡、因此也大大地影响一次爆破中可能喷出的飞尘比例 | The type and adequacy of the stemming material used and the management of progressive relief during detonation have a strong influence on the amount of material thrown into the air and hence the proportion of dust likely to be emit ted from a blast |
| 用质点振速表示爆破地震效应强度的原因1. 质点振动速度不受覆盖层类型及其厚度的影响。 2. 可适用于不同的测量仪器、不同的测量方法和不同的爆破条件。(3)结构的破坏与质点振动速度的相关关系比位移或加速度更为密切 | reason for using particle vibrating velocity to illustrate blasting vibration intensity |
| 由于对爆破影响最大的因素是地质、所以复杂的地质结构会使小规模的岩石爆破成为真正的爆破设计难题 | Since the factor having the greatest influence over blasting is geology, complex geologic structures can make small fragmentation a true blast design challenge |
| 调查结果表明、飞石事故是由以下一个以上的因素促成的: 地质及岩石结构的非连续性、炮孔布置和装药量不适当、抵抗线不足、炸药能量高度集中、填塞不足 | Investigations of flyrock accidents have revealed one or more of the following contributing factors: I discontinuity in the geology and rock structure,II improper blast hole layout and loading, III insufficient burden, IV very high explosive concentration, and V inadequate stemming |
| 这些制约着地下煤开采水平的混杂因素以及影响整个开采过程的地质因素、技术因素和经济因素复杂关系之间的相互作用、已在上文作了详细探讨 | The motley of factors that constrain the level of recovery in underground extraction of coal and the complex interplay of geologic, technologic and economic factors affection the overall recovery process have been discussed above in detail |
| 钻孔日志的地质信息 | geologic information in a drill log |
| 除了与地质和距离有关的因素外、还有一些因素与爆破作业设计直接相关。其中最重要的是每次延迟的最大装药量、即每次要爆炸的炸药最大量有时标明为每8毫秒间隔爆炸的炸药量 | In addition to factors that are related to geology and distance are those factors that are related directly to the design of blasting operations. The most important of these is the maximum charge weight per delay: that is, the maximum quantity of explosive that detonates at one time sometimes specified as being that which detonates within any eight millisecond period of time |
| 飞石产生的主要原因包括抵抗线不足、炮泥长度不够、钻孔不精确、单位炸药消耗量过多、地质条件不利露天节理、矿层不稳固和空穴、延时定时和序列不当、延时不精确、发生反向爆破、以及台阶上部岩石松散等 | The major causes of flyrock are inadequate burden, inadequate stemming length, drilling inaccuracy, excessive powder factor,unfavorable geological conditions open joints, weak seams and cavities, inappropriate delay timing and sequence, inaccuracy of delays, back break and loose rock on top of the bench |
