Working Conditions: Health & Safety
The interviews that were conducted indicate that miners sometimes work without personal protection, even when working below 70m depth, since that lowest level is being exploited by the cooperative as a whole. It is part of the collective contribution for the cooperative, out of their traditional mining-crew system. They have to help with the common costs of the cooperative by putting their own work at least 3 days a month in this new deep gallery. So it is not only unsafe and unhealthy to work there, but they also feel forced by the cooperative management to work there as an extra, because while those days are paid, the members are required to work inside the mine besides the days they already had to work with their crew to provide for their own income.
That depth is critical because there is less O2 and higher risks for lung diseases and silicosis, among others. They have to work there a minimum of 3 times a month: if they miss 2 times they are penalized and if they miss a 3rd time they lose their affiliation paper (the certificate of contribution to the cooperative) and they have to leave the cooperative. This level is accessed by an elevator system without emergency exit systems.
The interviewees imply that there is no safety plan in place and that occupational safety and health prevention systems are almost non-existent, probably due to the lack of resources from the management. On the contrary there are safety and health officers, but their functions are related to managing accidents and subsequent events, not preventing them!
A physical check shows that the concentration plants are constructions that are more than 50 years old and that there is no proper signage and ventilation. In general there are almost no risk and hazard signs inside the mine, or they are in constant deterioration and there is no plan for replacement of these signs.
The drilling of the rock inside the mine is not controlled: it should be done with water to avoid the formation of mineral dust suspended in the air, but there is no water system that reaches all the sites due to the investment cost involved. 74% claim to be exposed to gases and dust from rock blasting.
Because of these circumstances some miners have developed silicosis (a form of occupational lung disease caused by the inhalation of dust** due to the lack of water in the mining drilling process), rheumatism (due to excess humidity inside the mine) and head tumors (because of sliding rocks inside the mine, due to a lack of reinforcement of gallery infrastructure).
91% say that chemicals are not handled properly and more than 83% claim that there is continuous exposure to unprotected toxic materials such as xanthate and arsenic and that they have been exposed to fumes from the underground, for example those generated by diesel minecarts. The lack of ventilation systems generates a lot of combustion smoke that, according to one interviewees, affects mainly the “older” miners.
66% of the miners complain about occupational safety issues. Since everyone buys their own personal protective equipment, there is no industrial safety and it is not ensured. In the description of personal protective equipment, all describe the use of hearing protectors, respirators (but without a continuous change of filters and limited to the drilling of the rock) and head and feet protection, but no one has spoken about the use of back protectors. This is especially important because the minecarts are only present in the main galleries and from the undercuts they have to move the ore on their back in backpacks or sacks that carry a weight of about 40 kilos. There is evidence that they have to make walks of up to 30 minutes with this weight on top of them.
Within the mines there are no toilets or excreta disposal systems, therefore it is not allowed to relieve themselves inside the mine, for this they should wait for the change of shifts (7-13, 14-19).
On top of this the miners do not have clear and visible information about their rights within the cooperative: they do not receive an introduction, they lack information about their health insurance and they are poorly treated by the public health system, they are not trained in the handling of tools nor do they receive postural education, they are not taught to use personal protective equipment and so on.
