Comparative Tests of Run-of-Mine and Briquetted Coal on the Torpedo Boat Biddle (open access)

Comparative Tests of Run-of-Mine and Briquetted Coal on the Torpedo Boat Biddle

From Introduction: "With the particular equipment used in the tests both coal and briquets were far from smokeless; consequently the data of this bulletin are applicable only by analogy to parallel operation with a coal more nearly smokeless, but nevertheless applicable with much reliability. It was the original intention to make a set of preliminary steaming tests alongside a dock (which tests furnish material for this bulletin) an to finish with a set of running tests at sea; but the running tests were never made. for lack of time and men."

Tests of Run-of-Mine and Briquetted Coal in a Locomotive Boiler

From Object of Tests: "The primary object of the tests was to study the relative performances of the two types of briquets and of the coal, with reference to efficiency, tendency to smoke, and the ease with which steam could be kept up, when each of the three varieties of fuel was burned at several rates of combustion. Many secondary objects were in mind, the data concerning which are discussed under "Effect of varying rates of combustion," pages 20-27."

The Humidity of Mine Air with Especial Reference to Coal Mines in Illinois

From Introduction: "The investigative work described in this report was undertaken by the Bureau of Mines under a cooperative agreement with the department of mining engineering of the University of Illinois and the Illinois and Illinois State Geological Survey. The purpose of this agreement was to provide for a comprehensive investigation of coal-mining conditions in the State, with especial reference to the possibility of lessening waste in the mining and preparation of coal and of reducing the dangers to which miners are exposed. Thus, it studied the occurrence of gas (methane) in the mines of the southern part of the State, tested the inflammability of the coal dust from many mines, examined the efficiency of the control of ventilating currents, and investigated the factors affecting the humidity of mine air with respect to their bearing on the occurrence of mine explosions."

A Primer on Explosives for Metal Miners and Quarrymen

From introduction: "This bulletin aims to give the metal miner and the quarryman information similar to that given the coal miner in Bulletin 17. Inflammable gas or dust is seldom, if ever, found in quarries or metal mines, and the danger from using explosives there is less than in coal mines; but, as the figures show, the number of men killed and injured yearly in accidents caused by explosives proves the need of both miners and mine officials striving to see that none but proper explosives are used and these are used properly."
