21、一培训教材爆破设计与施工试题库(2012年修订版)第1章 基础理论试题1.1 应掌握部分的试题1.1.1 填空题1. 爆破安全技术包括爆破施工作业中的安全问题和爆破对周围建筑设施与环境安全影响两大部分。2. 长期研究和应用实践表明:工程爆破的发展前景正朝着精细化、科学化、数字化方向发展。3. 爆破器材的发展方向是高质量、多品种、低成本和生产工艺连续化。4. 小直径钎头,按硬质合金形状分为片式和球齿式。5. 手持式凿岩机可钻凿水平、倾斜及垂直向下方向的炮孔。6. 目前常采用的空压机的类型是风动空压机、电动空压机。7. 选择钎头时,主要根据凿岩机的类别,估计钻凿炮孔的最大直径,再根据所钻凿矿岩的岩
22、性、节理裂隙的发育情况,确定钎头类型和规格。8. 潜孔钻机是将冲击凿岩的工作机构置于孔内,这样结构可以减少凿岩能量损失。9. 潜孔钻机通过其风接头,将高压空气输入冲击器,依靠机械传动装置,可确保空心主轴输出的扭矩传递给钎杆。10. 牙轮钻机以独具特色的碾压机理破碎岩石,它的钻凿速度与轴压之间具有指数关系,增大轴压可以显著提高凿岩速度。11. 影响炸药殉爆距离的因素有装药密度、药量、药径、药包外壳和连接方式。12. 雷管和小直径药包底部有一凹穴,其作用是为了提高雷管和药包的聚能效应。13. 炸药爆炸必须具备的三个基本要素是:变化过程释放大量的热、变化过程必须是高速的、边界过程能产生大量气体。14
23、. 炸药化学反应的四种基本形式是:热分解、燃烧、爆炸和爆轰。15. 引起炸药爆炸的外部作用是:热能、机械能、爆炸能。16. 炸药爆炸所需的最低能量称临界起爆能。17. 炸药爆炸过程的热损失主要取决于爆炸过程中的热传导、热辐射、介质的塑性变形。18. 炸药的热化学参数有:爆热、爆温、爆压、19. 炸药的爆炸性能有:爆速、炸药威力、猛度、殉爆、间隙效应、聚能效应。20. 炸药按其组成分类有:单质炸药、混合炸药。21. 炸药按其作用特性分类有:起爆药、猛炸药、发射药、焰火剂。22. 爆破作业单位应当按照其资质等级承接爆破作业项目,爆破作业人员应当按照其资格等级从事爆破作业。23. 工业炸药按其主要化
24、学成分分类,可分为硝铵类炸药、硝化甘油类炸药、芳香族硝基化合物类炸药。24. 水胶炸药与胶状炸药没有严格的界限,二者的主要区别在于使用不同的敏化剂。25. 硝化甘油炸药具有抗水性强、密度大、爆炸威力大等优点。26. 爆破器材检验项目有:外观检验、爆炸性能检验和物理化学安定性检验。27. 瞬发电雷管有两种点火装置:直插式、引火头式。28. 允许在有瓦斯和煤尘爆炸危险的矿井所使用的铵梯炸药称为煤矿许用铵梯炸药。29. 导爆索是传递爆轰的起爆器材,其索芯是太安或黑索今。30. 电雷管的最高安全电流是指给电雷管通以恒定直流电,在一定时间(5min)内不会引燃引火头的最小电流强度。 31. 电雷管的最低
