Abstract

The invention belongs to the technical field of concrete spraying. A guniting auxiliary mine car comprises a walking chassis, a batching spiral assembly and a lifting conveying assembly, and at leasta first hopper and a second hopper are arranged on the walking chassis; the batching spiral assembly is arranged on the walking chassis, and the batching spiral assembly is used for taking materials from the hoppers, mixing and conveying the materials; and a feeding port of the lifting conveying assembly corresponds to a discharging port of the batching spiral assembly, and the lifting conveying assembly is used for lifting the mixed materials. The invention further discloses an underground guniting operation method. The mine car is reasonable in structural design, guniting materials can be loaded in the mine car hoppers on the ground and conveyed to a coal mine underground guniting site for a long distance, manual stirring and feeding are not needed on the site, the number of operators isreduced, the labor intensity is relieved, the operation efficiency is improved, and underground operation under various working conditions is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of concrete spraying, and in particular relates to a spraying auxiliary mine car and an underground spraying operation method. Background technique

[0002] At present, the tidal spraying process is mostly used in the underground operation of coal mines, and the rotor concrete spraying machine is used for spraying. When carrying out concrete spraying support operations in coal mines, for most coal mines in China, due to the narrow space of the roadway, large-scale concrete batching, mixing, and feeding equipment cannot be used, and there are still many manual batching, manual mixing, and manual feeding. In this way, the labor intensity of workers is high and the work efficiency is low. At the same time, manual mixing and feeding will cause a lot of dust, which will affect the health of workers; and manual mixing will not ensure uniformity, resulting in large spray rebound and serious waste. Some coal mines...
