目的 了解我省煤矿井下采掘作业地点气象条件现状 ,为井下作业人员职业防护提供依据。方法 按照国家标准规定的方法测定温度、相对湿度和风速 ,采用通风温湿度计和热球式风速仪测量。结果 4 4个作业场所干球温度范围 1 6 .0～ 2 8.6℃ ,3个作业地点不符合卫生标准 ;33个作业点风速符合卫生标准(75 % ) ,不符合卫生标准的主要原因是风速偏高。结论 井下作业管理者应针对不同作业地点气象条件 ,指导作业工人做好防护
Objective To understand the status quo of meteorological conditions in underground coal mining operations in coal mines in our province and provide evidence for the occupational protection of underground workers. Methods The temperature, relative humidity and wind speed were measured according to the national standards, and were measured by using ventilation hygrometer and hot ball anemometer. Results The dry-bulb temperature range of 46 working places was 16.0 ~ 28.6 ℃. The three work sites did not meet the hygiene standards. The wind speed of 33 work sites was in line with the hygiene standards (75%). The main reason for not meeting the hygiene standards was wind speed High. Conclusion Downhole operations managers should be based on meteorological conditions at different locations, to guide workers to do a good job of protection
