在煤炭生产的各个环节都会不同程度地产生粉尘,随着采掘机械化程度的提高,粉尘的产生量将增大,这种定性的研究是人所共知的。然而,各个生产环节产生多少粉尘?在气流中悬浮多少粉尘?采取防尘措施后能降低多少粉尘?这些问题只能通过测尘才能定量地获得解决。若通过测尘获得各生产场所的粉尘浓度超过国家规定的标准,则应采取防尘措施使其达到国家规定的标准。因此,不论从粉尘方面评价矿井的安全卫生状况,
In all aspects of coal production will produce dust to varying degrees, with the degree of mining mechanization, dust generation will increase, this qualitative study is well known. However, how much dust is produced at each production stage? How much dust is suspended in the airflow? How much dust can be reduced after the dust control measures? These problems can only be solved quantitatively by dust measurement. If the dust concentration in each place of production obtained by dust measurement exceeds the standard stipulated by the state, dust-proof measures should be taken to meet the standards stipulated by the state. Therefore, regardless of dust from the evaluation of mine safety and health conditions,
