Examination is performed on 87 miners from mine for copper production subject to intensive local vibrations with average rate of increase (K) of the norms for the individual octave frequencies 2.4 times for 3 h exposure of the working shift, as well as to intensive noise--113-115 dB/A equivalent level, general dust--23 mg/m3, fine dust--3.5 mg/m3 and fine quartz--0.43 mg/m3. There are data for vibration effect--changes in the cold test, vibration sensoriness, ultra sound sonometry, in all miners. In a significant part of them are established dyslipoproteinemia--increase of triglycerides, total and LDL cholesterol, values beyond reference (mainly above the norm) of 10 electrolytes and microelements in blood serum (blood). An extremely high prevalence of the cases and the days of total morbidity with temporary disability (respectively 189.7 and 2935 per 100), with predominance in its structure of diseases of the central and peripheral nervous systems, hypertension disease, etc. The importance of vibrations for disorder in the metabolic processes in the organism and development of temporary diseases are underlined.
对来自铜矿的87名矿工进行了检查，这些矿工受到强烈的局部振动影响，在一个工作班次3小时的暴露中，各个倍频程频率的标准平均增长率（K）为2.4倍，同时还受到强烈噪声——等效声级113 - 115 dB/A、总粉尘——23 mg/m³、细粉尘——3.5 mg/m³以及细石英——0.43 mg/m³的影响。有关于振动影响的数据——所有矿工的冷试验、振动感觉、超声测值的变化。在他们中的很大一部分人身上发现了血脂蛋白异常——甘油三酯、总胆固醇和低密度脂蛋白胆固醇升高，血清（血液）中10种电解质和微量元素的值超出参考范围（主要高于正常水平）。病例和因暂时丧失工作能力导致的总发病天数的患病率极高（分别为每100人中有189.7例和2935天），其中中枢和周围神经系统疾病、高血压病等疾病占主导。强调了振动对机体代谢过程紊乱和暂时疾病发展的重要性。
