辽宁省金州石棉矿认真贯彻加强防尘工作的指示,发动群众,自己动手,对原有设备较落后的粗选厂进行技术改造,取得了显著成果。通过近年来的努力,一个工艺设备简陋,粉尘很大的粗选厂,已被新的工艺、新的设备武装起来,不仅使粉尘基本上降低到国家规定的标准,改善了劳动条件,而且由于机械化水平的提高,提高了选棉效率,节省了劳动力,促进了生产发展。这个矿的粗选厂是适应石棉新采区的需要,于1960年建成投产的。原有设备比较简陋,工艺流程不够合理,因而粉尘比较严重,劳动条件较差。近几年来,他们在改善劳动条件、做好防尘密闭方面不断采取了许多措施,但是由于受工艺设备缺陷的限制,始终没有得到彻底解决。去年旅大市召开防尘会议以后,矿党委下决心要彻底解决这个问题,号召职工以自力更生,艰苦奋斗的革命精神,自己动手,改造工艺设备,坚决把粗选厂的粉尘降低到国家规定的标准。当即从矿部、各科室、车 The asbestos mine of Jinzhou, Liaoning Province, conscientiously implemented the instructions on strengthening the dust prevention work, mobilized the masses and did their own work, and carried out technical reformation on the roughing plant with less advanced equipment, with remarkable achievements. Thanks to recent years’ hard work, a rough, dusty roughing plant has been armed with new processes and new equipment. This has not only reduced the dust to the level set by the state, but has also improved working conditions. As a result of The improvement of the mechanization level has improved the cotton selection efficiency, saved the labor force and promoted the production development. The mine’s roughing plant is adapted to the needs of asbestos mining area, put into operation in 1960. The original equipment is relatively simple, the process is not reasonable enough, so the dust is more serious, poor working conditions. In recent years, they have taken many measures to improve working conditions and dust-tightness. However, due to the limitation of process equipment, they have not been completely solved. After Luda held a dust-proof conference last year, the coal mine party committee resolved to thoroughly solve this problem and called on workers to reform their technology and equipment by using the revolutionary spirit of self-reliance and hard work. standard.
