Risk Assessment and Safety Management in Underground Coal Excavation: A Case Study Analysis

Abstract This study investigates safety management and risk assessment practices in underground coal excavation, using Mine-A in Chandrapur, Maharashtra, as a representative case study. The primary objectives are to examine various risk assessment techniques, evaluate and analyze past excavation accidents, strengthen mine safety through hazard recognition and risk evaluation, and apply systematic risk assessment methodologies for effective risk control. A mixed-methods approach was adopted, integrating both quantitative and qualitative techniques. Historical accident data from 2014 to 2022 was analyzed alongside qualitative tools such as HAZOP, FTA, and ETA. The study covered ten major hazard categories and assessed worker exposure across multiple operational roles within Mine-A, which follows the Board and Pillar mining method and is classified as Degree-I in terms of gassiness. Results identified fire and inundation as high-risk hazards requiring immediate intervention. Medium-risk areas included ventilation and strata control systems. Accident data revealed support personnel and general workers as the most frequently affected groups. Additionally, national safety data from 2020 to 2022 indicated a consistent decline in fatal accidents and injuries, validating the effectiveness of structured risk assessment approaches. This study confirms their broader applicability in enhancing coal mine safety performance in India.
