Abstract
The purpose of this work was to investigate the rate at which coal is delivered from the underground working face by gathering arm type loaders as employed on continuous mining machines, to identify the factors--geometrical, geological, mechanical, or procedural--which affect the delivery rate, and to develop quantitative rate- descriptive equations for the loading function. The mathematical techniques employed were factor analysis and multiple linear regression. It was determined that the coal-cutting function of the continuous mining machine is the factor that primarily influences the loading function. The geometrical factors--the dimensions of the work area in relation to the dimensionsof the mining machine-- were the factors of secondary influence.
