Collapse of underground galleries in gold-panning mines: Perception of stakeholders in the Doko Sub-Prefecture, Siguiri Prefecture, Republic of Guinea

Abstract

Artisanal gold mining is recognized as a long-standing activity in the Siguiri prefecture in general and the Doko sub-prefecture in particular. Despite its significant contribution to community development, it has disastrous consequences for both the environment and the lives of gold miners. The collapse of underground galleries as a result of gold panning is a phenomenon that plunges families into mourning in gold panning areas in Africa. Unlike other land movements, despite their dangerous nature, there has been almost no scientific interest in limiting the consequences of collapsing underground galleries in goldmines. Working to mitigate their effects is more than a necessity for those involved in gold panning.This study aims to understand the perceptions of those involved in gold panning regarding the conditions of occurrence and the main causes of underground gallery collapses, to formulate recommendations to the authorities and gold miners to minimize the risk of these accidents occurring and their impact. The methodology used was based on semi-structured and structured interviews. The results of this survey show that the human factor is certainly the main cause of accidents (collapse of underground galleries), but the design of structures without taking into account the study of the geomechanical properties of the ground, the weakness of the safety measures put in place, and the lack of involvement of the country’s authorities are not negligible factors. This study identified the causes and consequences of these accidents, as well as the responsibilities of those involved.
