Abstract

Sandstone mining is a significant economic activity in many developing countries, particularly in Nigeria. In Imo State, located in the eastern region of the country, artisanal and small-scale sandstone mining is prevalent. This activity serves as a major source of livelihood for local communities, providing employment opportunities and contributing to regional economic development. However, these mining practices often pose substantial challenges in terms of efficiency, safety, and sustainability. This study investigates current sandstone mining methods, evaluates their impacts on safety and the environment, and proposes strategies for improvement. A mixed-methods approach-comprising field observations, interviews, and data analysis-was employed to develop a comprehensive understanding of artisanal and small-scale mining practices. The study critically examines existing safety measures for workers and assesses the environmental sustainability of mining operations. Additionally, it identifies the root causes of inefficiencies and proposes effective, sustainable solutions to enhance the overall performance of sandstone mining activities. The findings are expected to provide a deeper understanding of the challenges and opportunities within the sandstone mining sector in the eastern part of Imo State. Furthermore, this research offers actionable recommendations for stakeholders-including miners, regulatory agencies, and local communities-to improve the safety, efficiency, and environmental sustainability of sandstone mining, thereby contributing to the region’s overall development.
