EXPLOSIVE GASES WITHIN THE UNDERGROUND MINES are the gases (methane, higher hydrocarbons, hydrogen, carbon monoxide, and others), which are able to explode in case of the mixing with the air in the determined proportions.
EXPLOSIVE SUBSTANCES are the chemical compounds, or the mixtures of the substances, which are able, under the certain conditions, to perform the extremely rapid (explosive) self-propagating chemical transformation, with the release of the heat, and with the forming of the gaseous products.
EXPLOSIVE DUST is the dust, which, within the mixture with the air, is able to ignite spontaneously during the thermal and shock-wave impact.
EXPLOSION PROTECTION is the complex of the means for the ensuring of the normal operation of the equipment within the places, which are dangerous because of the explosion of the gas or dust (the mine workings of the underground mines, the beneficiation plants, and others).
EXPLOSIVE DEFORMATIONS is the change of the relative positions of the particles of the various solid bodies, which is associated with the movement of these particles under the action of the explosion.
EXPLOSIVE PACKER is the device for the closing and separation of the individual layers (petroleum, gas, and others) within the cased drilled boreholes, which is acting on the account of the energy of the explosion of the gunpowder charge.
EXPLOSIVE IMPULSE, see the "Impulse of the explosion" article.
EXPLOSIVE DESTRUCTION is the rapidly proceeding process of the partition of the solid medium into the separations under the action of the explosion.
EXPLOSIVE TRANSFORMATION is the self-propagating process of the extremely rapid change of the state of the substance (or of the mixture), which is accompanied by the release of the energy...
EXPLOSIVE COMBUSTION is one of the forms of the explosive transformation of the substances of the different aggregate state, which is propagating with the subsonic speed (from tens to hundreds metres per second).
EXPLOSIVE DRILLING is the method for the construction of the boreholes, using the destruction of the rock within the bottomhole, while using the successive explosions of the charges of the explosive substances, with the removal of the products of the destruction after each explosion.
EXPLOSIVE TECHNOLOGY is the deliberate destruction, movement, modification of the structure and shape of the natural (rocks, ice, wood) and artificial (metals, plastics, concrete, and so on) materials, which is performed on the account of the energy from the explosion.
EXPLOSION is the process of the rapid physical-chemical transformation of the substance, during which the energy is released, and the work is performed.
