摘要： A blasting arrangement (10) includes drillholes (30) in a rock mass (20). Blind ends (32) are drilled to a desired level and, if necessary, are adjusted as shown at (62) to said level. Each hole (30) is plugged by means of a plug (42), which is protected by non flammable buffer material (44), at a level (40) spaced from the end (32). Explosive (50) is charged above the level (40) and the hole is tamped, shown at (60). The holes are detonated desirably by detonators (52), forcing the plugs (42) downwardly and compressing air in chambers (34) above the ends (32). The weakest part of each hole, around the end (32), is split causing a three dimensional zone of weakness at the level of the ends (32). Air forced into the zone of weakness causes a fracture zone (70) at that level, inhibiting propagation of blasting shock waves and protecting the material underneath the level of the ends (32).
摘要翻译：爆破装置（10）包括岩体（20）中的钻孔（30）。将盲端（32）钻到所需的水平面上，如果需要，将其调整为（62）所示的水平。每个孔（30）通过由不可燃缓冲材料（44）保护的塞子（42）在与端部（32）间隔开的水平（40）处堵塞。爆炸物（50）被充电到水平面（40）上，孔被夯实，如（60）所示。这些孔期望地由引爆器（52）引爆，迫使塞子（42）向下并压缩在端部（32）上方的腔室（34）中的空气。每个孔的最弱部分（32）围绕端部（32）被分裂，导致端部（32）的水平处的三维弱点区域。被迫进入弱化区的空气导致在该水平的断裂带（70），从而抑制爆破冲击波的传播并保护端部（32）的下方的材料。

摘要： A plug for use in a borehole, the plug including a body member of a flexible material, the body member defining a floor portion, with a wall portion bounding and extending from the floor portion for engagement with an inner wall of the borehole for sealing the borehole. The invention also relates to a method of supporting materials in a borehole.

摘要： A drill hole (350) extends into rock to be blasted. A blasting accessory (310) includes a container portion (312) for holding a predetermined volume of stemming material, and a spacer (330) for spacing the stemming material a predetermined distance from a surface, e.g. a blind bottom of the drill hole. The container portion has a top (320) surrounded by a dilatable, inverted skirt forming a seal (342), and forms a support for a blasting substance like an explosive.
摘要翻译：钻孔（350）延伸到要被喷砂的岩石中。爆破附件（310）包括用于保持预定体积的引茎材料的容器部分（312），以及用于将引脚材料与表面隔开预定距离的间隔物（330）。钻孔的盲底。容器部分具有由可膨胀的倒立的裙部围绕的顶部（320），形成密封件（342），并形成诸如爆炸物的爆破物质的支撑。
