Degree of confinement or confinement factor (C f): It is a ratio between blast-hole length (L h) and cross-sectional area (a) of blasting faces [35].It is well witnessed that longer raises are quite difficult to blast in a single-shot due to its confinement, and hence, confinement factor of raise is very crucial for LHR technique.

1. Introduction. Blasting is known as the first phase of mining operation which is conducted with the aim of worthy rock mass fragmentation. Nevertheless, the appropriate rock fragmentation is performed by 20% of total explosive energy; however, the rest is wasted by adverse environmental side consequences such as flyrock, dusts and …
In blasting operations, natural cracks in the rock mass structure are changed by additional stresses induced by the blasting, and the shear strength of the structural surface is significantly reduced, thereby decreasing the stability of the rock [1, 2]. Studies on blast vibration harm control are conducted based on analysis of blast …

The blast-induced strain at monitoring stations is estimated by Equation (4) [48]. (4) e = PPV C p × 1000. Where PPA is peak particle acceleration, PPV is peak particle velocity and C p is the P-wave velocity of the medium. The blast-induced dynamics strain is important to understand the failure characteristic of concrete [11], [49]. Strain ...
Blasting is accompanied by a number of side effects that have a negative impact on the environment, such as ground vibration, flyrock, AOp, and backbreaks [33, 42].These effects are more severe if they are carried out in close proximity to residential buildings, factories, offices or if they are improperly designed [].Proper designing of a blasting operation …
Abstract. Blasting is a major means for excavation of rock slope, and the blast-induced damage to reserved rock mass must be strictly limited to ensure safety of the high slope and reduce the cost for support. As a traditional and widely used technique, the sonic wave testing is usually adopted to detect the extents of blasting damage, but the …
