Methods of delivering inhibited emulsions are provided. The methods can include mixing an emulsion with a separate inhibitor solution to form the inhibited emulsion. Inhibitor solutions including water, an inhibitor, and a crystallization point modified are provided. Systems for delivering inhibited emulsions are also provided.

Approaches to loading explosives into blast holes to provide increased explosive density can involve loading the hole with a detonable charge in which energetic material is arranged into zones of differing densities. Related systems and methods may provide for parallel independent streams of energetic material having differing densities and delivering the differentiated streams into a bore hole so as to create an explosive charge therein having a particular geometric arrangement of material from the respective streams.

A method, system and apparatus for plasma blasting comprises a solid object having a borehole, a blast probe comprising a high voltage electrode and a ground electrode separated by a dielectric separator, wherein the high voltage electrode and the dielectric separator constitute an adjustable probe tip, and an adjustment unit coupled to the adjustable probe tip, wherein the adjustment unit is configured to selectively extend or retract the adjustable probe tip relative to the ground electrode and a blasting media, wherein at least a portion of the high voltage electrode and the ground electrode are submerged in the blast media. The blasting media comprises water. The adjustable tip permits fine-tuning of the blast. The blast can be used to fracture solids and/or to create a shockwave to mapping underground structures.
