The blasting process remains a potential source of numerous environmental and safety accidents. The majority of these accidents were contributed to the flyrock and lack of blast area security. A field-scale investigation related to flyrock accident was conducted in an andesite quarry where rocks up to 50 cm in diameter were propelled almost 300 m from the center of blasting field causing extensive damages to the surrounding objects. The study revealed that accident occurred due to the existence of andesite alteration in one section of the blast field. The existence of this alteration caused a sliding of rock masses along the subsistent joint planes and thereby reduced burden for the second row of blastholes. Alterations involved small area of andesite masses that were not detected by previous geological exploration or visually observed prior to initiation of blastholes. The result of this filed investigation should have a positive impact on hazard awareness, prevention and safe blasting practices in mining and construction industries.
