本章簡(jiǎn)介將用相關(guān)的生產(chǎn)炮孔來(lái)介紹爆破損傷區(qū)（BDT）概念。隨著開采區(qū)域的擴(kuò)大，爆破損傷過(guò)渡區(qū)的也自動(dòng)擴(kuò)大，除非采用特別的技術(shù)例如線性鉆孔或者預(yù)裂爆破技術(shù)。這一部分將會(huì)討論這兩種技術(shù)。為了能更方便的討論損傷控制技術(shù)，看表10.7，在該表中概略的顯示了直徑從9-7/8英寸的裝滿炸藥炮孔的損傷區(qū)域。根據(jù)損傷的程度可以很方便的將損傷區(qū)域細(xì)分為三個(gè)區(qū)域。每個(gè)區(qū)域的范圍都是以到藥包中心的半徑來(lái)衡量。在這個(gè)表中的損傷區(qū)域的范圍（以炮孔直徑D描述的）和得到的相應(yīng)的PPV值是使用銨油炸藥在中等強(qiáng)度的巖石中爆破得出的結(jié)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 ......
