2018-3-1  Mining blasts may be defined as the use of explosive charges in a controlled manner by following a tightly controlled timing sequence according to an assigned firing order. Changes of timing between charges may result in an altered firing order and failure of the blasting sequence, which can cause high vibration levels, poor fragmentation, and/or an undesirable rock mass movement direction.

Expansive Rock Breaking Non-Explosive Demolition

Expanding Grout is a mixture of elements that initiates when water is added to the dry mix. As the grout sets, the material expands, producing 18,000 psi of force on the drill hole it is poured into. The expansive force will cause the rock or concrete to break, in a low controlled demolition.

2018-3-1  A deck is a layer of non-explosive material in a borehole which separates the explosive column into two parts so that two in-hole detonators are required to initiate the explosive charges. In addition to the in-hole detonators, 25 ms delays are used on the surface to ensure each charge is initiated by delay intervals of 25 ms in sequence.

Drilling and Blasting Technical Aspects of Mining

Mining is the largest consumer of civil explosives. Mining explosives are substances which detonate to produce a high-intensity shock wave and large volumes of gas which, being confined in a hole, expand rapidly, entering existing minor cracks in the rock, and creating new cracks to break the rock.
