The former of mucking loader is collecting arm-type loader. After the technology was introduced from Sweden in 1980s, it was mainly used in railway and water diversion tunnel construction. The company has developed different kinds of loaders many times and updated them to adapt to different working conditions including section from 1.8 × 1.8m to 9 × 9 m (H × W), slope within 30º. Since it was widely used in recent years, it has become an alternative of the old scraper type rock loader.
Main characteristics: Electro hydraulic control system: the mechanism adopts taking and static raking type, with less resistance. After it passes through scraper conveyor to install coal gangue continuously and rake completely ...
Tunneling Program Solution 1: Full-hydraulic drill jumbo +mining mucking loader + shuttle mining car (group) + belt elevating conveyor +multi-mining trolley + locomotive.
Description of the Tunneling Program: When excavating main tunnel in vertical well, mining mucking loader pulls multi-shuttle mining car and belt elevating conveyor to working surface. The locomotive pushes mining cars onto the rail that is parallel to shuttle mining car. The loader puts gangue into shuttle mining car continuously. Then gangue is dumped into mining cars through belt elevating conveyor ...
Inclined roadway, especially inclined roadway with large inclination is always bottle neck for mine and non-mine main tunnel. There is no ideal equipment for loading gangue, which limits excavating speed. In the past, load gangue was loaded through traditional crawler loader or manually. Traditional crawler loader has disadvantages such as low efficiency, uncompleted slagging and impossibility to rake because of much water in the tunnel.
The company has developed many types of mucking loader (it has obtained national patent) special for large slope, which is used to load gangue on the slope ≤30º. It is provided with cable reel, which can make the loader draw in and draw out the cable easily, save labor and increase safety factor. In addition, after it is used together with large transportation equipment, it can shorten loading time of gangue, reduce the number of workers ...
Program 7: Mining mucking loader (special for large slope) + Side dumping belt conveyor+ fixed belt conveyor + traction winch
This program is applicable to long roadway and slope< 20º. Mucking loader (special for large slope) is used to excavate and pick up slag. Then slag is loaded through second transportation belt and transported through main belt conveyor. When blasting, the double-purpose belt is pulled up against traction winch on the ground. When placing material cars, second transportation belt is against the rear part of mining mucking loader. This program is mainly used for permanent belt laid at one time and roadways on permanent rail. It has advantages such as quick and continuous withdrawal of slag.
A set of gangue draining system is shared aiming at multi-working faces. Transshipment cycle time of tunneling work face is long, which caused in short supply and restricted tunneling speed, For the above phenomenon,one or more large shuttle mining car (s) is/are arranged under the storage bin to act as the storage bins; the gangues are continuously and vertically discharged into the tramcar group through the shuttle tramcar, so that the working efficiency and the tunneling speed are improved, and the labor intensity is reduced ...
Shuttle Mining Car is arranged in the contract lane of a downhill lane and a gangway and is usually used for buffering gangues when the downhill lane is tunneled. In the tunneling process without the buffering of the Shuttle Mining Cars, the front tunneling is usually discontinuous, and the slagging is restricted; and the tunneling is restricted by the delayed slagging.
Typical case:
Xinjiang Lli (Hazi Gold Mine)
Shanxi Tongmei Group (Dongzhouyao Coal Mine)
The main tunnel is developed under the vertical shaft; the shuttle mining car matched with the mucking loader is adopted in the gangway; after the shuttle mining cars unload the slag into the forward dumping wagon, the forward dumping wagon is lifted. By the reasonable matching, the working efficiency is improved while the mechanized operation level is promoted.
