我们于1979年1～4月,对十个矿山1150名男性凿岩工进行了振动性白指流行病学及临床的调查研究,同时对劳动条件和振动工具的物理参数进行调查。 调查对象与方法 共调查十个矿山,其中煤矿两个、铁矿两个(一个露天矿),有色金属矿五个、人防工程一个。较小的矿山则对全部井下凿岩工(包括过去从事过凿岩工作的工人)进行检查,较大的矿山则选抽1～3个有代表性的坑口进行检查。此外有的矿对井下运搬、支柱等工种不接触振动的工人作为对照组进行检查。本调查的白指为旁证白指。
From January to April 1979, we investigated the epidemiological and clinical investigation of vibrating white fingers on 1,150 male rock drills in ten mines, and investigated the working conditions and the physical parameters of the vibration tools. Survey of objects and methods surveyed a total of 10 mines, of which two coal mines, two iron ore (an open pit mine), five non-ferrous metal mine, a civil air defense project. Smaller mines conduct inspections on all downhole rock drillers, including those who used to drill in the past, while larger mines select 1 to 3 representative chasm for inspection. In addition, some mines carried out inspections on underground transportations and pillars, workers who did not touch the vibration as a control group. The survey refers to the white refers to the evidence of white.
