随着采矿工业的发展,接触振动机具,尤其是凿岩机的工人日益增多,发生振动病的可能性也增加了。 振动病是由于接触每分钟在1,800—18,000次的振动频率而引起的。振动病冬季比夏季容易发生。热带气候,即使接触振动,也不易患振动病。因此,一般认为振动是振动病的基本因素,寒冷是振 With the development of the mining industry, the number of workers exposed to vibrating machinery, especially rock drills, has increased and the possibility of vibrancy has also increased. Vibratory disease is caused by a vibrational frequency of 1,800-18,000 vibrations per minute. Vibration sickness winter easier than summer. Tropical climate, even in contact with vibration, not susceptible to vibration disease. Therefore, it is generally believed that vibration is the basic factor of vibration disease, the cold is vibration
