为了掌握金矿选矿作业工人职业危害情况,保护工人健康,促进黄金事业发展,我们对黑河金矿两个精选厂进行了劳动卫生调查。1 内容与方法1.1 生产性噪声测定 用ND—10型声级计测定生产性噪声强度,使用前经黑龙江省计量检定测试所检定,测定方法按《黑龙江省劳动卫生监测规范》进行。1.2 职业性健康检查 两个精选厂的41名工人为接触组,后勤35名工人为对照组。体检项目与方法按卫生部颁布的《劳动卫生工作规范》进行,听力测定用新购置的日本产MST-1型电子测听仪,尿汞测定用F732型测汞仪检测。1.3 尾矿天然辐射水平测定 使用上海产FD—71辐射仪,使用前经黑龙江省电离辐射仪器仪表检定站检定。测定方法参照
In order to grasp the occupational hazards of gold dressing workers, protect the health of workers and promote the development of the gold business, we conducted a survey on labor hygiene in two selected factories in Heihe Gold Mine. 1 Content and methods 1.1 Determination of production noise ND-10-type sound level meter to determine the production of noise intensity, the use of Heilongjiang Province before the test by the verification test, measurement methods according to “Heilongjiang Labor Health Monitoring Code.” Occupational Health Checks 41 workers in the two selected plants were in contact groups and 35 in logistics were control subjects. Physical examination items and methods according to the Ministry of Health promulgated the “Code of labor and health work”, the hearing test with the newly purchased Japanese-made MST-1-type electronic audiometer, urinary mercury measured with F732 mercury detector. 1.3 Tailings natural radiation level determination using Shanghai FD-71 radiometer, before use by the Heilongjiang Ionizing Radiation Instrument Verification Station test.
