煤矿井下作业职业病危害预评价与控制效果评价验证分析

Pre-assessments of occupation disease hazard of colliery under-pit operation and validation of control effect evaluation

目的：了解煤矿井下作业职业病危害预评价类比企业选择的合理性，并核实预评价提出建议的落实情况。方法以某煤矿的可行性研究报告、职业病危害预评价报告与控制效果评价报告为基础资料，对预评价和控制效果评价的职业病危害因素识别与检测、防护设施与防护用品、职业卫生管理等内容进行对比验证。结果该建设项目职业病危害预评价与控制效果评价在职业病危害因素识别、防护设施与防护用品等方面基本一致，控制效果评价的职业病危害因素检测结果合格率高于预评价，但差异无显著性（P＞0．05）；建设单位根据预评价报告的建议在职业卫生管理方面进行了改进。结论该建设项目与类比企业具有较高的相似性，对检测结果的预测性较好，预评价对建设单位的职业病危害因素控制和职业卫生管理起到了指导性作用。

Objective To survey the rationality of analog enterprise selection of pre‐assessments of occupa‐tion disease hazard of colliery underpit operation and verify the fulfillment of proposal suggested by pre‐as‐sessments .Methods The identification and detection of occupational disease risk factors by pre‐assess‐ment and control effect evaluation ,protective facilities and articles as well as occupational health manage‐ment were contrastively validated according to the basic information of feasibility study report ,pre‐assess‐ment report of occupation disease hazard ,pre‐assessment report of occupational hazard harm and evalua‐tion report of control effect of a certain coal mine .Results The pre‐assessment of occupational disease hazard of this building project was elementarily consistent with the evaluation of control effect in the iden‐tification of occupational disease risk factors ,protective facilities and articles ,the qualified rate of occupa‐tional disease risk factors form the evaluation of control effect was higher than that from pre‐assessment , but difference wasn’t significant （P〉0 .05）;client had improved occupational health management accord‐ing to the suggestion of pre‐assessment .Conclusion The building project has higher similarity with analo‐gy enterprises ,predictability of detection result is better ,and pre‐assessment plays a directive role in the control of clients’ occupational disease risk factors and the management of occupational health .
