Here, is the mass burning rate (g/cm s) with impact of liquid viscosity p is the viscosity of a liquid (poise) P2 is the density (g/cm ) of gas productions S is the density of a liquid explosive. 

The application of liquid explosives refers the explosion in rocks and earth. The stratum (including rocks and soil) is a kind of nonuniform media. There are large gaps between rocks and rocks, rocks and the soil, soil and soil. Even in the same rocks, there are big differences in the textures, structures, or mechanical properties. Study of explosion in the rocks is more complex compared to that in the air or under water. To study the impact of liquid explosives in the mining, explosions in infinite rocks and infinite half rocks are discussed here. 

The cyanide is a friction- and impact-sensitive explosive, and may initiate detonation of liquid hydrogen cyanide. Other heavy metal cyanides are similar. 

Mechanical impact on a road surface on to which liquid oxygen had leaked caused a violent explosion [1], Anecdotal evidence that there have been several like incidents is given [2], Mixtures of asphalt and liquid oxygen were shown to be impact-sensitive on the small scale, but on the larger scale a detonator was necessary to initiate mild explosion of liquid oxygen on a layer of asphalt [3], Oil,... 

Addition of liquid air to ether in a dish caused a violent explosion after a short delay. Previous demonstrations had been uneventful, though it was known that such mixtures were impact- and friction-sensitive.

Modes a), b) c) presumably operate in the usual impact and/or friction initiation of pressed solid explosives, and modes a) b) in the impact and/or friction initiation of liquid explosives. Modes e), f)> g) h) operate in the shock initiation (and possibly the propagation) of detonation in solid explosive compacts or explosive liquids containing inhomogeneities. 

Picatinny arsenal (PA) impact apparatus The sample which is placed in the depression of a small steel die-cup and then capped by a thin brass cover, is used in this test. The value of minimum height at which at least one out of ten trials results in explosion gives impact sensitivity. In the case of liquids, it is filled in a die-cup and tested in a manner similar to solids. 

The crystalline a-dinitrate hydrate explodes under the impact of a weight dropped from a height of 90-100 cm for explosion of the liquid /S-isomer a drop of only 30-40 cm is required.
