A mine multi-purpose vertical shaft pipeline material conveying system

Abstract

The invention discloses a mine multipurpose vertical well pipeline type material conveying system. The mine multipurpose vertical well pipeline type material conveying system includes an over-well conveying system, a vertical pipeline conveying system, a material slowing system, an anti-spilling storage system, an under-well conveying system and a pipeline sedimentation pre-warning system which are successively connected; the over-well conveying system is arranged on a well; and the vertical pipeline conveying system is arranged in a vertical well wall. The beneficial effects of the inventionare that the material conveying system can be applied to conveying of a bulk filling material in a solid filling coal mining technology; an original functional vertical well shaft is reconstructed, safe conveying of the bulk filling material from a ground surface to the well can be achieved; offset and vertical sinking of a wear-resisting vertical pipe can be intelligently monitored in real time;and the multipurpose vertical shaft pipeline type material conveying system is easy to use, is safe and reliable, is high in adaptability, can avoid re-digging of a feeding well, can reduce the production cost of filling and coal compression, and has wide application prospect in the solid filling coal mining technology.

Description

Technical field [0001] The invention relates to a mine multi-purpose vertical shaft pipeline type material conveying system, which belongs to the technical field of mine transportation. Background technique [0002] With the increasing demand for "three-under" compressed coal mining, solid-filled coal mining technology has been widely used in mining areas that face technical problems such as mining under buildings, mining under water, and mining under railways. The up and down transportation system of bulk filling materials is one of the important systems of solid filling coal mining technology. At present, the feeding method of bulk filling materials is mainly by digging a feeding hole vertically from the ground to the well, and installing a feeding pipe as a filling material The conveying channel can be filled with materials to realize direct delivery from the ground to the underground. [0003] Although the above method can realize the transportation of bulk filling materials u...

AI Technical Summary

Problems solved by technology

[0003] Although the above method can realize the up-and-down transportation of bulk filling materials, it needs to excavate a new feeding hole, which has the disadvantages of high excavation cost and long construction period, which greatly increases the burden on the mine.
