一、前言: 煤是工业、交通运输业的原动力和某些化学工业的原料。煤藏量山西几乎占全国二分之一,有煤海之称。从事该工作的人数以万计,但是纯煤尘究竟对人有无危害、游离SiO_2在煤尘中所起的作用,至今国内外文献尚有争论,尤其国内这方面的资料更缺乏,以及如何使用新技术和综合措施降尘尚需进一步研究,根据党的科研、生产、实际相结合的教育方针,在大搞科研,面向生产的前提下,根据中央和华北协作区科研计划。我们在西铭煤矿七里沟坑,进行了煤肺及其防治的研究,为时约两个半月,包括外环境测定,职业史的询问,体格检查、胸部X片的照象,动物试验,防尘措施,借以探讨煤肺在我国 First, the foreword: Coal is the driving force of industry, transportation and some chemical industry raw materials. Shanxi Province, accounting for almost half of the country’s coal reserves, coal sea said. There are tens of thousands of people engaged in this work. However, whether pure coal dust is harmless to human beings or not and the role played by free SiO_2 in coal dust has been debated in the literature both at home and abroad. In particular, there is a lack of domestic data on this subject and how The use of new technologies and comprehensive measures to reduce dust need further study. According to the party’s scientific research, production and actual combination of education policy, in the large-scale scientific research, production-oriented premise, according to the Central and North China collaborative area scientific research plan. We conducted a study on the coal lung and its prevention and control at Qilioukeng of Ximing Coal Mine, which took about two and a half months, including external environment measurement, inquiry about occupational history, physical examination, radiography of chest radiographs, animal experiments, prevention Dust measures to explore coal lung in our country
