【摘要】：为研究煤矿井下环境相对封闭、空间相对有限的情况下,噪声对作业人员的影响及危害,通过问卷调查的形式,分别对开滦集团东欢坨及荆各庄2煤矿井下5个不同作业区人员进行了共计200份的噪声危害问卷调查。将问卷调查结果通过SPSS软件进行统计与分析,并将SPSS分析得到的数据用于分析井下噪声对作业人员的影响及危害,归纳出噪声对作业人员的影响因素,并对噪声、影响因素及症状之间建立了井下噪声对作业人员影响的理论关系模型。结果表明:在井下有限空间内,噪声对作业人员的危害最严重的症状是耳鸣,危害最轻的症状是畏惧感;参与调查的多为年龄较大、工龄较长的作业人员,噪声对工龄较长者的危害程度要大于对年龄较大者,且工龄与噪声危害之间存在Pearson相关性系数大于0的正相关关系。
[Abstract]:In order to study the effect and harm of noise on workers under the condition of relatively closed underground environment and limited space, a questionnaire survey was conducted. A total of 200 noise hazard questionnaires were carried out in Donghuantuo and Jinggezhuang 2 coal mines of Kailuan Group. The results were analyzed by SPSS software. The data obtained from SPSS analysis are used to analyze the influence and harm of downhole noise on operators, and the influence factors of noise on operators are summarized. A theoretical model of the influence of downhole noise on operators was established between the factors and symptoms. The results show that the most serious symptom of noise to operators is tinnitus and the least harmful symptom is fear in the limited space of underground. Most of the workers who participated in the investigation were older and older, and the degree of noise harm to the older workers was greater than that of the older ones, and there was a positive correlation between the Pearson correlation coefficient and the noise hazard.
