张春茂、朱居敬(新疆有色金属公司卫生处)报道:可可托海矿,位于阿尔泰山,海拔高度为1200～3200m。年平均气温为-2.08℃,冬季严寒。50年代初主要为坑下开采,未能进行湿式作业,粉尘浓度可高达2081.2mg/m~3之多,矿尘危害十分严重。为贯彻1956年国务院颁布的关于防止厂矿企业中矽尘危害的决定”,矿务局十分重视,由总工程师亲自抓防尘工作,并成立防尘研究小组,制定防尘措施,检查防尘实效,大力宣传提高职工对矽尘危害的认识;夏季露天作业可用水降尘,冬季坚持干式扑尘。机选厂在矿石通过的漏斗上按装暖气
Zhang Chunmao, Zhu Jujing (Xinjiang Nonferrous Metals Company Health Department) Report: Kekeituhai Mine, located in the Altai Mountains, has an altitude of 1200 ~ 3200m. The annual average temperature of -2.08 ℃, winter cold. In the early 1950s, it was mainly pit mining, which failed to carry out wet work. The dust concentration could reach as high as 2081.2mg / m ~ 3, and the dust hazard was very serious. In order to implement the decision of the State Council in 1956 on preventing the harm of silica dust in the factories and mines, the Mining Bureau attached great importance to the work. The chief engineer personally took the work of dust prevention and set up a research team on dust prevention to formulate dust prevention measures and check the effectiveness of dust prevention , Vigorously promote the workers awareness of the dangers of silica dust; summer open-air operations can be used to reduce dust, dry adhere to the dry winter dust.
