Blast Event Management

BEM Process:

Ritech believes that in quarry business, the maximum profitability depends largely on good blasting which depends largely on best drilling design. Both of these criteria have been incorporated into Ritech’s Blast Event Management process (Annexure – II). Further, Ritech BEM takes into account standardised global working practices, a good approach to safety and ensures statutory compliances; thus leading to high success ratio of optimum fragmentation. Thus, Ritech’s high success ratio of optimum fragmentation is due to very carefully designed BEM process wherein design of each blast – as a part of overall quarry / mine plan – forms an integral part of the process. We follow rigorous guidelines in Ritech designs, and when accurately implemented in the field – such as the blasts must be shot in a safe manner, with the area properly barricaded and all persons removed at a safe distance away - the environmental effects, e.g. ground vibration, noise of air-blast and dust - fume production, are within allowable limits or controlled.

BEM Features:

Statutory and Safety Considerations and compliances

Optimum Blast Design

  - Face preparation,

  - Drilling hole size and design

  - Explosives optimisation for good fragmentation

Measurement of necessary blast parameters by Instrumentation during

  - Pre Blast

  - During Blast (video shooting, safe way to shot blast, proper barricaded are, all persons safe distance away)

  - Post Blast (photos / video ,ground vibration, noise level, dust / fume production)

K50 Analysis


Periodic Updating of Mine plan

BEM Benefits:
  - Safe blast from statutory, environment and human habitant

  - Good and uniform fragmentation evaluation by K50 analysis,

  - Cost effective blast

  - Consistency and uniformity in production - Continuous feed to crusher plant

  - Build up of knowledge base.
