Abstract

Abstract

The paper makes an exhaustive study on the velocity pattern and the constant velocity body of solo drawing-hole on the basis of the expected value body (EVB) drawing theory, makes up for the defect of same study on the basis of the ellipsoid drawing theory. The paper aquires an important conclusion.
- caving systerm,
- solo drawing-hole drawing,
- velocity pattern,
- constant velocity body
