Pdf Optimiation Of Blasting Parameters In Opencast

2020-5-15Drilling and blasting are the major unit operations in opencast mining. Inspite of the best efforts to introduce mechaniation in the opencast mines blasting continue to dominate the production. Therefore to cut down the cost of production optimal fragmentation from properly designed blasting pattern has to be achieved. Proper adoption of drilling and blasting can contribute significantly

Predicting Ground Vibration Induced By Rock Blasting

Blasting operation is considered as one of the cheapest methods to break the rock into small pieces in surface and underground mines. Ground vibration is a side effect of blasting and can result in damage to or failure of nearby structures. Therefore it is imperative to predict ground vibration in the blasting sites. The primary objective of this paper is to propose a new model to predict
