为了减少索赔事件的发生、炸药的使用人员保存完整的爆破作业记录是聪明的举措、监测爆破振动和冲击波、尽可能通知公众、尽量降低钻孔和交通噪声、减少粉尘并减小其他可觉察到的影响In order to reduce damage claims, the explosives user is wise to keep complete records of his operations, to monitor vibrations and airblast, to do what he can to inform the public, and to minimize drilling noise,dust,traffic noise, and other perceptible effects
噪声的安全标准噪声对人体健康的危害和环境的污染是多方面的,但总的说来可以分为两大类:一类是声级较高的噪声,可能引起听力损伤以及神经系统和心血管系统等方面的疾病, 另一类是一般声级的噪声,可能引起人们的烦恼,破坏正常的生活环境。将噪声控制在一定水平上所制定的标准称安全标准safety standard of noise
噪音源的声能谱sound power spectrum of the noise source
地震噪声在地震反射法中,一般认为除一次反射的地震能量外的其他能量都是地震噪声,包括微震、激发引起的干扰、多次波、磁带调制噪声和谐波畸变等seismic noise
当炸药威力大、产生的震感强、噪声大、飞石多。如果炸药威力太小、由于抵抗线和围压增加、会导致爆破失败、而且对于每次延时所用的药量而言、所产生的振动会比预计的要大While a high powder factor may generate higher levels of vibration, noise and flyrock, a power factor that is too low may cause a blast to fail and may generate more vibration than expected for the charge per delay that was used, because of increased burden and confinement
振动与噪声试验器vibration and noise tester
水下周围噪声underwater ambient noise levels
消除爆破噪声abatement of blasting noise
源致噪声地震勘探中震源产生的噪声,如地滚波、空气波等source generated noise
爆破噪声炸药在空气中爆炸时,在爆源附近产生冲击波,经过一定距离后衰减成声波并向远处传播。爆破噪声是指以声波为主的噪声noise of blasting
爆破噪声与大气条件的关系大气条件对在一定距离内爆破产生的噪声强度有重大影响。大气条件还决定了在不同高度和方向上空气中的声速,而声速本身又主要取决于温度和风速,因此,从大气中风速和温度的变化也能了解大气条件对爆破噪声的影响relationship between blasting noise and weather
爆破噪声与药量的关系据实验数据用统计方法得出的某采石场二次破碎时爆破噪声与装药量的经验公式如下:p = 6 * 10⁻³Q⁰.⁵²。式中, p 为测点声压,Pa;Q为一次爆破的总装药量,kgrelationship between blasting noise and charge quantity
爆破噪声的预防防止或减少爆破噪声的方法和措施。爆破噪声的基本原理是由爆破空气冲击波衰减而成的。因此,关于控制爆破空气冲击波的措施,也可作为控制爆破噪声的措施preventive measures of blasting noise
近来的研究提供了更为准确的气象数据、可以用来预测和评价诸如噪声、飞尘抑制、气体排放以及冲击波超压等对环境的影响Recent research has provided more accurate meteorological data that may be used for the prediction and assessment of environmental effects such as noise, dust control, and gaseous emission as well as airblast overpressure
