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

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1-Figure 5 As shown, the rapid delivery equipment system used in the one well and two warehouse type rapid delivery method for deep roadway grouting and pouring concrete materials includes: receiving funnel 1, and an iron grate is set on the receiving funnel 1, and the filtering area of ​​the iron grate is 40mm ×40mm, to prevent unqualified large-size materials from entering the silo, and reduce the risk of blockage of the feeding pipe during the later feeding process. Stone silo 3, sand silo 4, stone powder silo 5, and cement silo 6 arranged in a line; they are arranged on the top between the feeding funnel 1 and the stone silo 3, sand silo 4, and stone powder silo 5. Material belt conveyor 2; belt conveyor 10 located below the gravel silo 3, sand silo 4, stone powder silo 5 and cement silo 6 to the mouth of the feeding well; st...

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 ...
