The fundamental theory promoting the use of stemming enhancement plugs is that they could potentially improve the effectiveness of stemming material in the blast hole. This would, in turn, better contain the explosives energy within the rock mass, and yield a more controlled and efficient blast event. The three keys to efficient blasting are: 1.

Today, primary crushing is viewed as more important within the balance of production and proper sizing needs. The size and type of the primary crusher should be coordinated with the type of stone, drilling and blasting patterns, and the size of the loading machine. Most operations will use a gyratory, jaw or impact crusher for primary crushing.

Thus it is crucial to control the adverse effects of blasting. 1. Factors Affecting Vibration. When a controlled blast is fired, the vibration level is controlled by two principal factors, distance and charge size. Obviously, it is safer to be far away from a blast than to be near it. 2. Safe Limits of Vibration.
