One-well two-bin type quick conveying method for deep tunnel guniting and concreting materials

Abstract

The invention discloses a one-well two-bin type quick conveying method for deep tunnel guniting and concreting materials. Corresponding materials are conveyed to a stone bin, a limestone powder bin, a sand bin and a cement bin on the ground through a feeding belt conveyor, a weighing type belt feeder is arranged under the stone bin, a spiral feeder is arranged under each of the sand bin, the limestone powder bin and the cement bin, the materials are reasonably proportioned by regulating the feeding speed, and the proportioned materials are conveyed to a feeding wellhead via a belt conveyor. The guniting and concreting materials are fed from a feed inlet in periods of time, the concrete materials are led to enter corresponding underground storage bins via a prismatic buffer, and mixing and classified storage of the materials are realized. The materials are discharged to a mine car through belt feeders of lower storage bin ports, and then the materials are conveyed to a needed place via traction of an electric locomotive. Through quick classified storage and conveyance of the guniting and concreting materials, safe and quick tunneling of a mine tunnel is realized.

Description

technical field [0001] The invention relates to a deep roadway spraying and pouring concrete material fast delivery method in one well and two warehouses, belonging to the field of concrete material transportation. It is especially suitable for the construction of new mines and the development of new mining areas, assisting the transportation of concrete materials when the transportation pressure is high. Background technique [0002] The construction of roadways and chambers in underground coal mines requires a large amount of grouting and pouring of concrete materials. Concrete materials are transported from the ground to the underground. The speed of material transportation directly affects the speed of roadway excavation and the efficient recovery of working faces. Under normal circumstances, the mine developed in the vertical shaft can transport the concrete material to the underground through the lifting of the auxiliary shaft. However, with the continuous improvement ...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the mine developed in the vertical shaft can transport the concrete material to the underground through the lifting of the auxiliary shaft. However, with the continuous improvement of the production capacity of the mine, the auxiliary lifting pressure of the mine is relatively high. The limited lifting capacity of the auxiliary shaft intensifies the pressure of the auxiliary lifting. Therefore, many mines carry out reconstruction and expansion projects. Reasonable; on the other hand, the lifting and transportation of the auxiliary shaft cannot realize the continuous transportation of concrete materials, which restricts the demand for concrete materials underground
