Assessment of the Operations of Stone Crushers in Artisanal and Small Scale Granite Quarries

摘要

Estimation of the respective productivities of men and women stone crushers in Artisanal and Small Scale Granite Quarries was carried out by collecting data from sample sites and conducting statistical treatment of collected data. An analysis of the results shows that the productivities of men and women stone crushers are 1.1 and 0.6 tonnes per day. Based on these results, a rating scale of output and required manpower in Artisanal Granite quarries was developed using interval and nominal rating methods.
