Excerpt from The Rate of Burning of Fuse: As Influenced by Temperature and PressureIt will thus be seen that either retardation or acceleration in the rate of burning of fuse can readily become the cause of accident, and accordingly the study of the conditions under which the rate of burning Of fuse is so changed as to cause the fuse to burn more rapidly or more slowly becomes of particular importance.Miners have frequently noticed that fuse, when surrounded by very dense stemming material, as in a. Hole that has been firmly tamped, burns faster than it should. In this case the dense and im permeable stemming prevents the free escape of the gases from the powder, and so compresses them in their attempt to escape as to bring about a decided quickening in the rate of burning. As the use of firm stemming is nearly always desirable, one can readily see that information as to the degree of quickening in the rate of burning Of fuse under these conditions is essential in order that the miner may in such cases know what additional length Of fuse is necessary to provide for the increased rate of burning.Retardation in the rate of burning of fuse is a serious fault. Cases are known, though fortunately very few, in which a piece of fuse has seemingly stopped burning, and yet after an interval of one or more hours has brought about the explosion of the charge to which it was attached. Cases of this sort never happen with fuse that is in good condition, but may sometimes happen when fuse is of poor manufacture or has been subjected to unfavorable conditions of moisture or temperature.The conditions that are believed to be most active in bringing about either a retardation or an acceleration in the rate of burning of time fuse have been investigated experimentally, and the results that have been obtained will be classified in this report under effects due to: (a) Pressure, (6) temperature, (0) moisture, (d) mechanical injury.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
