Quarry Safety – Bengaluru District Halts 48 Sites After Boulder Collapse
Quarry Safety – Mining safety concerns have come under renewed focus after a boulder collapse at a quarry near Huluvenahalli village reportedly claimed the lives of seven workers. Authorities have suspended operations at all 48 quarries in Bengaluru Urban district while officials examine the circumstances surrounding the incident.
Residents raise concerns over buffer zone compliance
Villagers alleged that quarrying and blasting work was carried out too close to the boundary between adjoining sites. They said the required 7.5-metre safety buffer around quarry lease limits was not maintained, increasing the danger for labourers working nearby.
Lakshmi Narayana, a resident of Huluvenahalli, said the Directorate General of Mines Safety guidelines prohibit mining and blasting activity within the designated buffer area. According to him, operations at two neighbouring quarries may have continued inside this restricted space.
He also questioned the effectiveness of inspections by the Department of Mines and Geology, alleging that safety requirements were not adequately enforced at the site before the accident.
Claims of unsafe blasting practices
Another resident said quarry operators in the area were under pressure to extract more stone in less time, which may have led to unsafe working methods. He alleged that some operators relied on stronger blasts rather than using smaller, controlled charges in a phased manner.
The resident further claimed that inspections often focused on licences and paperwork instead of verifying conditions on the ground. These allegations have not been independently confirmed by authorities.
A local resident, Ramaiah, said there may have been blasting activity in the upper quarry area before the collapse. He alleged that broken boulders and explosive wires were seen near the site, raising questions about whether earlier blasting had weakened the rock formation.
Workers allegedly lacked protective equipment
Residents also alleged that several workers at the quarry were not given basic protective gear, including helmets, gloves and safety boots. Narayana said many labourers depend on daily wages and may avoid raising concerns over safety equipment because they fear losing their employment.
Mining work involves significant risks, particularly during excavation, drilling and blasting. Safety equipment, controlled operations and regular monitoring are considered essential to reduce the possibility of accidents at quarry sites.
All operating quarries temporarily closed
Following the fatal incident, the Department of Mines and Geology ordered a temporary shutdown of all 48 quarries operating in Bengaluru Urban district.
Senior Geologist Krishna Veni said the department would hold discussions with quarry owners and ensure that mine safety requirements are followed more strictly. She said quarry operators had been instructed to comply with safety norms about 15 days before the incident.
Veni added that the owners of both quarries linked to the incident held valid licences. The temporary closure is expected to allow officials to review safety arrangements, examine compliance with mining rules and determine whether further action is required.
Investigation expected to examine safety lapses
The incident has prompted renewed calls from residents for stronger field inspections and accountability in quarry operations. Local people have urged authorities to verify whether buffer zones, blasting procedures and worker protection standards are being followed at every site.
The investigation is likely to focus on the alleged violation of buffer zone rules, the nature of blasting carried out near the quarry boundary and the availability of safety equipment for workers. Further action will depend on the findings of the official inquiry.
