Abstract :
The Committee on Applications to Mining Work has done very little constructive work during the past year. From the nature of things, the Committee can only watch the development of the use of electric power in mines. This use is becoming more general every year and electric motors are supplanting every other kind of motive power. This is due, of course, to their higher efficiency and flexibility of control, combined with the fact that they are just as reliable, if properly designed for mine use, as any of the other forms of drive. I think that no mine operator who is contemplating the opening of a new mine would consider any other method of drive.
