本章简介将用相关的生产炮孔来介绍爆破损伤区（BDT）概念。随着开采区域的扩大，爆破损伤过渡区的也自动扩大，除非采用特别的技术例如线性钻孔或者预裂爆破技术。这一部分将会讨论这两种技术。为了能更方便的讨论损伤控制技术，看表10.7，在该表中概略的显示了直径从9-7/8英寸的装满炸药炮孔的损伤区域。根据损伤的程度可以很方便的将损伤区域细分为三个区域。每个区域的范围都是以到药包中心的半径来衡量。在这个表中的损伤区域的范围（以炮孔直径D描述的）和得到的相应的PPV值是使用铵油炸药在中等强度的岩石中爆破得出的结果 ......
SPECIAL DAMAGE CONTROL TECHNIQUES
Introduction
In the introduction to this chapter the concept of a blast damage transition zone (BDT) was presented with respect to the production holes. As the pit expands outward, the BDT follows along automatically unless some special measures are taken such as line drilling or pre-splitting. These are two of the techniques which will be discussed in this section. To facilitate this discussion on damage control techniques, consider the BDT shown diagrammatically in Figure 10.7 for a fully-charged 9-7/8" diameter hole. It is convenient to subdivide the BDT into three zones based upon the level of damage. The extent of each zone is characterized by a radius from the center of the production charge. The zones, their extent (as expressed in terms of the hole diameter D) and the corresponding PPV values resulting when using ANFO in medium strength rock are assumed to be as follows ......
