Primary exploration onthe .motion law of solid bulk materia of waste rock thrown in large aperture vertical line
Abstract：Waste rock, used in coal mining of solid filling and filling bulk materia of fly ash, are transported down the well from ground through transporting system of large aperture vertical line. This paper takes filling bulk materia thrown vertically in wells of large aperture line as the objects of study, analyzes forces of filling materia comprehensively with gas - solid two - phase flow, obtains primarily the motion law and the relevant theory calculation of filling materia in wells used for materia throwing, analyzes its flow shape and builds its math model, deduces its max flow velocity. This paper plays a certain theoretical guiding role in the design of vertical filling bulk materia throwing system.
