Mining Haulage

The technology of mining is the subject of this fascinating book, and two companion volumes, all of which were originally published in 1907. Mining: Haulage details the railways that operate in the underground world of the mine. This historic book has been reprinted in its entirety. It¿s a treat for anyone who ever worked underground, or for anyone who ever wondered, ¿How does that work?¿

Haulage related Accidents in Metal and Nonmetal Surface Mines

Haulage trucks enjoy widespread use in surface mining operations and are a major cause of death and injury among surface miners . ... This work was done as part of the U.S. Bureau of Mines program to improve mining haulage safety .

Haulage related Accidents in Metal and Nonmetal Surface Mines

Frequencies of haulage-related accidents in metal and nonmetal surface mines for the years 1988 through 1990 were investigated and compared with those of non-haulage-related accidents. This study was part of the U.S. Bureau of Mines program to improve mining haulage safety. Data were obtained through the U.S. Bureau of Mines Accident Data Analysis (ADA) program. The chi-square test was used to compare frequencies of haulage-related and non-haulage-related accidents for each of the following variables: degree of injury, age, total number of years of mining experience, and shift time. Significance was determined for degree of injury between haulage-related and non-haulage-related accidents. Age of injured did not vary significantly between haulage-related and non-haulage-related accidents, but total number of years of mining experience was found to be significant. Shift time for the accident proved to vary significantly between haulage-and non-haulage-related accidents. Events causing injury for haulage-related accidents were tabulated, and the most frequent determinants of haulage-related accidents were identified. Accident descriptions for both fatalities and permanent disabilities were studied, and the primary causes of these accidents were identified. These findings suggest that haulage-related jobs are among the most dangerous when considering accidents experienced by all workers in the metal and nonmetal surface mining work force.

Design of Surface Mine Haulage Roads

This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions. Traffic control and design of proper lane widths to promote safe vehicle movement are included, as are suggested criteria for road and vehicle maintenance and for runaway vehicle safety provisions. The aim of this publication is to provide those involved with surface mine haulage road design with a complete manual of recommended practices that, if implemented, will promote safer, more efficient haulage routes.

Underground Electric Haulage

Underground Electric Haulage focuses on the locomotives used in modern mine railways. The locomotives of many different types are used for such underground operations as gathering at the loading points, shunting at the pit bottom, hauling man-riding vehicles, but primarily hauling material cars on the main haulage roads of the mine. The locomotives for underground haulage fall into three main groups: (1) compressed-air locomotives, (2) internal-combustion locomotives, and (3) electric locomotives. So far as electric haulage is concerned, the locomotives may be divided into two types: (a) trolley locomotives and (b) storage-battery locomotives. Besides these two main types there are also various combinations, such as trolley locomotives with batteries, cable-reel locomotives with a reel for the automatic unwinding and winding up of the cable, and trolley locomotives fitted additionally with the cable-reel equipment. The book is organized into three parts. Parts I and II discusses trolley locomotives and storage-battery locomotives, respectively, while Part III deals with calculations in mine traction engineering.
