为了解铜矿凿岩工人局部振动的危害情况,我们于1985年1月份对某铜矿井下作业的111名工人,进行了局部振动危害职业流行病学调查。同时现场记录凿岩工人每日实际接触振动的时间,还就两种不同型号凿岩机的振动参数进行测试,报告如下:
In order to understand the damage caused by the local vibration of copper miners, we conducted a survey on the occupational vibration hazard of 111 workers in a copper mine in January 1985. At the same time on-site records of rock drills daily actual contact with the vibration time, but also on two different types of rock drill vibration parameters are tested, the report is as follows:
