根据《东北三省矽肺防治科研协作计划》的要求,我们协作组承担了“辽宁省金属矿山综合性防尘措施的卫生学研究”这一科研题目。结合我组具体情况,于一九七六年对我省七个有色金属矿山采场、掘进、装卸矿等作业中的单项、综合防尘技术措施效果进行了卫生学评价。在此基础上,为加强科学性,我组又于一九七七年集中力量,深入到一个矿山,对我省有色金属矿山井下目前广泛使用的各种防尘技术措施效果进行了第二次评价。这次评价工作承蒙东北工学院通风教研组给予热情协助和指导,在此致谢。现将测定结果评价如下:
According to the requirements of the “Collaborative Plan for Prevention and Control of Silicosis in Three Provinces of Northeast China”, our collaborative group undertook the research topic of “Hygienic Study on Comprehensive Dust Control Measures for Metallic Mines in Liaoning Province”. According to the specific conditions of our group, hygiene evaluation was made in 1976 on the effect of single and integrated dust-proof technical measures in the stope, digging, loading and unloading operations of seven non-ferrous metal mines in Shaanxi Province. On this basis, in order to strengthen the scientific nature, our group concentrated again in 1977 on a mine and carried out the second time on the effect of various dust-proof technical measures currently widely used in the underground nonferrous metal mines in our province Evaluation. Thanks to the warm teaching and research team from Northeastern Polytechnic Institute for Ventilation, this evaluation is gratefully acknowledged. Evaluation results are as follows:
