With the speed of onset of silicosis survey


Wu 褰 base development in Guizhou plateau gold mining. Longhui County farmers to hire young adults from more than man-made mining 1lO migrant workers - in the absence of mechanical ventilation, dust-free exploration of the underground facilities of the 20m gold. Gold production for the pneumatic drill blasting rock drilling mining beneficiation. Mining drill down from the wind in the Department of Mineral base-type operations, resulting in dust filled face. Concentration range up to 1.5m can not see the shadows. For the pursuit of economic efficiency - at forced labor of migrant workers gingival ten hours. Migrant workers with technical training through the dust-qu l, no dust-protection knowledge, only ten months and ten each of 4 layers of gauze masks, resulting in a lack of protective measures for migrant workers in the case.

Dust, the average time to death was 38 October. Silicosis from diagnosis to death for the average time was 21 months, the mortality 14.6.2.2 prevalence of different types and length of service workers pneumatic drill 47. 30 down the incidence - incidence rate of 63.83, the incidence of working age in 6 to 29 October, the average length of service as l3.12 onset of October.
