露天采石场主要包括凿岩、爆破、大块石预破碎、挖掘机装车、汽车运输、破碎、筛分、堆垛等8道工序,每道工序都存在职业危害因素。凿岩、大块石预破碎、破碎、筛分、堆垛等工序均产生大量粉尘,同时产生噪声、振动,防尘、防噪成为露天采石场职业卫生管理的关键。在对露天采石场进行职业卫生监察时,重点要检查产生粉尘、噪声的作业区场所管理是否符合职业卫生法规标准,包括是否在醒目位置设置公 Opencast quarry mainly includes drilling, blasting, large stone pre-crushing, excavator loading, motor transport, crushing, screening, stacking and other eight processes, there are occupational hazards in each process. Drilling, large stone pre-crushing, crushing, screening, stacking and other processes have a lot of dust, while noise, vibration, dust, noise become the key to occupational health management of opencast quarry. When conducting occupational health inspection on open-air quarries, it is important to check whether the management of the workplace where the dust and noise are generated meets the occupational health and regulatory standards, including whether the public is set in a prominent place
