为了解局部振动作业对煤矿井下掘进工人健康的危害,我们对石炭井某矿进行了振动作业劳动卫生学调查,对井下掘进工73人做了体检,其中资料完整的45人做为接振组;并选工龄、年龄相仿不接触噪声振动的同矿男性工人40名为对照组。调查项目及结果掘进作业现场气温17.7℃,湿度85％。风速2.5m/s,两台YT—24型气腿式凿岩机作业,用ZDJ—1型人体振动计在现场测得凿岩机手柄处振动加速度为50.12m/s~2,两台凿岩机同时工作其噪声强度107dB(A);体检按《职业性局部振动病诊断标准及处理原则(GB4869—85)》(以下简称标准)规
In order to understand the health hazards of coal miners working under local vibrations, we conducted a survey on labor hygiene of vibrating work in a mine in Carboniferous. We conducted a physical examination of 73 underground miners, of which 45 were complete with complete data. ; And choose the same age, age without exposure to noise and vibration of the same mine 40 male workers as the control group. Survey project and the results of tunneling site temperature 17.7 ℃, humidity 85%. The wind speed of 2.5m / s, two YT-24 type air leg rock drill operations, the use of ZDJ-1 human vibration meter measured at the site of the rock drill handle vibration acceleration of 50.12m / s ~ 2, two rock drills work simultaneously noise Intensity 107dB (A); physical examination according to the “Occupational Vibration Diagnostic Criteria and Principles (GB4869-85)” (hereinafter referred to as the standard) regulations
