摘要(Abstract)：

混凝土地坪的爆破拆除既可以用常规浅孔破碎法也可以用透孔法。使用透孔法时,炮孔穿过混凝土地坪,药包位于孔内地坪和垫层的接触面附近。本文介绍了透孔法的基本原理,对常规浅孔法和透孔法主要爆破参数进行了比较;利用一个实例,阐述了透孔法相对于常规浅孔法的优、缺点;同时指出了使用透孔法的限制因素。
Both common shallow-hole blasting and through-hole blasting can be used for demolition of concrete ground. In the through-hole blasting method, all of boreholes pass through the concrete ground and the charge is near to the contact plane between concrete ground and pad layer. In this paper, the principle of the through-hole blasting method is introduced and the blasting parameters of shallow-hole method and through-hole method are compared. With a practical example, the advantages and disadvantages of the through-hole method, relative to the common shallow-hole method, are expounded. At the same time, the restrictions on use of the through-hole method are pointed out.
