English term for coal-mining explosives which have passed special tests as explosives assuring a sufficient safety for use in coal mines where inflammable mixtures of methane and air occur. In the U.S.A. they are called permissible explosives. [Pg.399]

Coal Mining Explosives, Testing for Permissibility. In order to manuf an expl which will not ignite expl mixts of air with firedamp and/or coal dust, it is advisable to consider... [Pg.151]

The fee for all of these tests is 1200. As it is charged whether the expl passes all the tests for permissibility or not, it is advisable not to siibmit them until some of their thermochemical properties are calcd. For this purpose, the method of calcn given in this vol of Encycl, under COAL MINING EXPLOSIVES, Permissible may be used. If the calcn shows that the expl does not fulfil the theoretical requirements for permissibility , its compn should be changed before submitting the expl to Bureau of Mines... [Pg.152]

Further development of expls safe against firedamp and/or coal dust will be discussed in section II of this item, entitled Coal Mining Explosives, Permissible. In section I, which follows, are described commercial expls which are not permitted in gaseous and/or dusty coal mines, but can be used for many other purposes... [Pg.220]

Coal Mining Explosives, Permissible (Permitted in GtBritain). This term applies to explosives which, because they have passed special prescribed tests, can be used in coal mines eontg firedamp and/or coal dust. These tests are described under COAL MINING EXPLOSIVES, TESTING FOR PERMISSIBILITY- Approved expls will not ignite expl mixts of firedamp, coal dust 8t air, when used under prescribed conditions. [Pg.227]

In US practice, an expl in order to be placed on a A "Permissible List , should undergo a series of tests designed to prove that it will not cause the ignition of the following expl mixts firedamp air coal dust air and firedamp coal dust air (See also under COAL MINING EXPLOSIVES, TESTING FOR PERMISSIBILITY)... [Pg.228]
