Health and safety of mining workers require extra attention. The continuous monitoring of physical and chemical agents, possibly harmful, is essential to verify the efficiency of preventive actions and to identify new risks situations. This job has to be carried out by qualified professionals that can even be the company's employees, since well trained. However, the required information for guidance is not easily found at the specific bibliographies. Thus, the goal of this work is to prepare a comprehensive guide of field measurements with some sampling tips, including the description of the physical and chemical agents, equipments examples, and the associated methodology. The results were analyzed and compared with the current Brazilian standards. This study considered the most harmful agents in a quarry: noise, illuminance, silica dust, human vibration and heat stress which were measured with some of the several equipments available in the market. This guide, with suggested monitoring practices, can be extended to other mining environments. The results were helpful in proposing enhancements to safety and health of miners.
