The drive head of the stage loader, where it dumps coal into the panel belt conveyor, rides on the belt tail pieces on a dolly that can travel freely for a distance of 3.7–4.6 m. So as a new cut is made, the gate-end shields advance and push the cross frame and the whole stage loader a web distance ahead. (3).
Matt Miller, Longwall Stage Loader Operator and Mine Rescue/First Aid Team Member, arrived at the scene. Miller checked the victim's vital signs and found none. The victim was placed on a stretcher and transported to the surface area of the mine. Phillip Russell, Jefferson County Deputy Coroner, arrived at the mine site and
Bridge Stage Loader Bridge Stage Loader is mainly used for conveying coal at the gate road,can be connected with crusher, end frame, scraper or belt conveyor to form a complete set.If necessary,it can be matched with self-moving device of the stage loaders and self-moving tail end of the belt conveyors, meeting the requirements of high capacity and high efficiency working face for high ...
A premining investigation laid the groundwork for mine design and equipment specifications. Four-legged shields, a face conveyor, a stage loader and an in-web shearer were selected to operate on a 183 m face. Longwall mining began in 1979 and initially was slowed by low mining height and equipment problems.

Equipment Beam Stage Loader and Crusher. When the coal has been hauled to the maingate, it then has to be transferred through a 90 o turn, and loaded onto the maingate conveyor. This function is carried out by the "Beam Stage Loader or BSL", which is another scraper conveyor, in this case with steel plates on both sides and runs from the maingate drive to the maingate conveyor (belt).

This longwall has made history in Chinese mining. It was the first longwall with perpendicular machine sumping and also the first longwall to operate in fully automatic mode, including automatic hoisting of the beam stage loader. This is a special achievement also due to the fact that it was a low thickness seam wall (1.40-1.55 m).
Some portion of the coal falls on the floor, this coal is shovel to the AFC by fillers. T he shearer always move and remains on the AFC. The coal from AFC passes through a lump breaker. The lump breakers break the bigger size coal to normal size. The coal from AFC comes to stage loader. Stage loader …
This evolution of longwall equipment has resulted in significant increases in power requiremients such that the combined horse- power for the face conveyor, shearer, stage loader, crusher, and hydraulic pumps can now exceed 5000 hp. With increased power requirements, the traditional utilization voltage of …
can be assumed that machines included in the longwall system together with a beam stage loader and a crusher have the greatest impact on the effectiveness of the entire exploitation process. From the reliability point of view, the studied set of machines is a serial structure system and it means that it properly works when all its components are efficient (Fig. 5).
The new shearer and stage loader are scheduled to go into operation in Narrabri's longwall block number 5, which is about 300 meters wide and will have an extraction height of 4.2 meters. Seam height is 8 to 10 meters, but Whitehaven determined that extending the longwall face—to as wide as 400 meters—will be more cost effective than ...
Cutting Machines - Shearers. Shearers are by far the most commonly used cutting machines, both in Australia and overseas. A shearer consists of a machine body containing electric motors, hydraulic equipment and controls which is mounted over the AFC. Horizontal cutting drums are mounted on the face side of the machine, laced with cutting picks ...

Longwall development began in 1987 with the first face commissioned in 1989. Since that time, Twentymile has produced a cumulative total nearing 100Mt of coal, with Peabody planning major investment in new longwall equipment for the mine during 2005. ... armoured face conveyor and stage-loader supplied by Deutsche Bergbau Technik (DBT).

longwall end of the stage loader. However, much of the stage loader remained covered. Tr. 35, 72, 74. When standing in the headgate entry facing the longwall, the controls for the stage loader were located on its left side, approximately in the middle of the equipment. Tr. 39; see Gov. Exh. 6.

The beam stage loader includes a SK11/14 crusher with 400 kW (536 hp) installed power. Pan width is 1,342 mm (0.05 in). The longwall face at Yalevskogo mine is equipped with customized two-leg roof supports, each with a width of 1.75 meters (5.75 feet) and support capacity of 725 tonnes (800 tons).
So its advance is concurrent with the stage loader. All three self-advancing hydraulic supports are elctrohydraulically controlled. The headgate set, 5.5-m long x 4.05-m wide x 3-m high (18×13.3×9.8 ft) provides a support density of 0.201 MPa (2.1 tons/ft2), while the tailgate sets, 5.03 m long x 2.84 m wide x 2.7 m high (16.5×9.3×8.9 ft ...
workers. For instance, one study of a longwall stage loader operator revealed that he spent a considerable portion of his shift positioned at the belt tailpiece, which is one of the noisiest locations along the stage loader.

BEAM STAGE LOADER. When the coal is transported by the AFC along the longwall face it reaches the beam stage loader at the end of the face. The beam stage loader is simply a chain conveyor that transport coal from the AFC to the main belt conveyor. Also incorporated into the beam stage loader …
Equipment centric factors studied in the paper are repair times of operational equipment in the longwall panel such as Armored Face Conveyor (AFC), Bridge Stage Loader (BSL), shearer, chock supports, main gate drive, crusher, gate road conveyor and hydraulic pumps in addition to delays due to overloading of conveyors and bins [18].
Longwall Face Chain Conveyors (or Armored Face Conveyors) are designed for smooth, transport of coal in high-volume coalfaces where shearers and powered roof supports are used.. Beam stage loader systems used together with a crusher, belt receiving section (commonly called a Boot End) and advancing equipment are designed for smooth, transport of coal from high-volume coalfaces to the …
The stage loader/crusher component at the headgate of a longwall is generally completely enclosed. The dust control from this source is addressed by proper design of the transfer/loader/crusher system sprays, adequate construction to eliminate leakage of dust-laden air from the system, adequate airflow in the entry, and good maintenance around ...
