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。
In order to study the influence and harm of noise to workers under the condition of relatively closed environment and relatively limited space in underground coal mine, five different operation areas of Donghuan Tuo and Jinggezhuang 2 coal mines of Kailuan Group were investigated respectively by means of questionnaire survey. The staff conducted a total of 200 noise hazard questionnaires. The results of the questionnaire were collected and analyzed by SPSS software. The data from SPSS was used to analyze the influence and harm of downhole noise on workers. The influencing factors of noise on workers were summarized. And the influence of noise, influencing factors and symptoms Established between the noise downhole workers on the theoretical relationship model. The results show that the most serious symptom of noise in the limited underground space is tinnitus, and the least harmful symptom is fear. Most of the workers involved in the survey are older and longer service workers. The harm of the older persons is greater than that of the older persons, and there is a positive correlation between Pearson correlation coefficients greater than 0 between the length of service and the noise hazards.
