AbstractBlasting is a common practice in surface mining operations to remove waste rock and to excavate mineral deposits. However, blasting creates adverse effects such as blast-induced ground vibrations, air overpressure, dust, fumes, and flyrock. Residential communities living close to a mine site and other structures in the vicinity of a mining operation are subject to blast-induced damages. Humans can perceive low-level vibrations from blasting events that cause house to shake. They become concerned about cosmetic or structural damages due to blast-induced vibrations and air overpressures. Some cosmetic and structural damage claims from the community are legitimate. However, many are found to be false during the investigation of citizen complaints. In these instances, monetary compensation is still expected, on the basis that damages were solely due to blasting activities in nearby mines. This study presents cases and investigations to resolve owner-filed complaints for regulatory action and monetary compensation. It emphasizes recordkeeping and monitoring of blast operations, from which two positive outcomes result: (1) assisting regulatory authorities in assessing compliance with blasting regulations and prevention of damage to structures; and (2) helping the mining industry identify critical blasting information needed to protect nearby structures minimize liability claims.
