Safe blasting practises at Rampura-Agucha mine

摘要

In today's scenario there being the burgeoning demand for supply of minerals with limited ore reserve in hand, planning big size blast has become a need of the hour. En route to execution of this, utilization of latest mining methods coupled with efficient blasting technique based on state of the art explosives characteristics are becoming popular gradually. Blasting is one of the major activities in the cycle of mining operations which influences the whole process right from drilling up to crushing. And using of latest generation commercial bulk explosives in this regard has proved to the best source of energy. Though inherently safe, handling and using of bulk explosives in a big blast are always fraught with risks and dangers which demands for one to be in a state of alert all time. Unsavoury situations like accidental detonation or ignition of accessories, premature detonation of blast hole, post blast generation of fly rocks, ground vibration, fumes, dust and noise are always a threat to a good blast and kept in mind while designing a large size blast using bulk explosives. This document specifies established procedures that shall be followed while proposing to a blast using commercial bulk explosives at RAM world's largest producer of lead-zinc. Following this procedure can help ensure that the entire blasting operations can be accomplished in a safe and effective manner consistent with economy, achieving higher productivity and preservation of ecology.
