Specific power consumption as factor disintegration process control of digging-wheel excavators

Original language description

The determination of digging resistance is of decisive importance when evaluating the mining process of digging-wheel excavators. Methodics of measuring and determinant relations (formulae) are different in various countries and by the comparison of them, underlying data for complex and objective evaluation using the knowledge from the field of rock disintegration can be obtained.In virtue of analysis of many measurements in situ, a rather high specific power consumption with a wheel of excavator has been proved. What was the criterion for evaluation was the power consumption related to the volume of a rock disintegrated per unit time. From theoretical analyses, possibilities of eliminating a negative influence of the human factor upon the mining process and thus possibilities of optimum utilizing the power input of a wheel drive follow.
