MATHEMATICAL EQUATIONS OF THE DISPLACEMENT PROCESS OF BROKEN ORE IN CAVING SYSTEM (Ⅱ)

In this paper, some mathematical equations for calculating the width of displacement zone. depres-sion velocity and trace of broken ore lump, draw channel depression curve and draw body (drawprofile) resulted from ore drawing in caving mining are given. Meanwhile, it has been proven byanalysing and testing that the equations given in this paper conform reality well.
