Problems solved by technology

[0004] Especially in plows operating in reverse, the presence of dangling chains can continue to cause serious problems and / or lead to chain breaks
In addition, the disadvantage of reversingly operated coal mining equipment is that the end stops for reversing the movement of the plow body must have a considerable distance from the plow sprocket, and that the drive station is designed to be relatively large

Embodiment Construction

[0019] exist figure 1 6 shows a greatly simplified schematic diagram of the six different operating states of a coal plowing plant generally designated by reference number 1 during a reversing cycle. exist figure 1In the coal plowing equipment 1, the reference number 2 represents the coal plow traction chain 5 for having an upper return strand 3 and a lower traction strand 4 driven by means of an unillustrated drive unit of a drive station The driving sprocket 2 of reference numeral 6 represents the diverting sprocket of an unillustrated reverse station without driving. In this plowing plant 1 only the drive sprocket 2 is driven by means of a drive. A reversingly operating coal plow 7 is driven in the direction of movement B or B′ by means of a plow traction chain 5 driven by the drive sprocket 2 and deflected at the diverting sprocket 6 . exist figure 1 In sub-figures I, II and III, the coal plow 7 moves from the driven drive sprocket 2 to the non-driven diverting sprocke...

Abstract

A method for mining and a planer installation for the mining of coal, with a coal planer that can be moved by a planer chain that can be driven via a drive chain wheel of a drive station for the planer chain and that is deflected at a deflection chain wheel of a driveless deflection station. The coal planer is moved back and forth reversibly between the drive station and the deflection station bythe planer chain to avoid the occurrence of sag and to minimize the necessary size of an auxiliary drift to be opened. The deflection chain wheel is mounted on a slide that can be displaced in the direction of movement of the coal planer by a tension device.

Description

technical field [0001] The invention relates to a method of mining coal with a coal plowing device. The coal plowing equipment has a coal planer, and the coal planer is driven by means of a coal planer traction chain, and the coal planer traction chain is driven by a coal planer with a driving device. The drive sprocket of the drive station of the chain is driven and deflected at the deflection sprocket of an in particular non-drive deflection station. Secondly, the invention also relates to a coal plowing device for mining coal, which has a coal planer, which can be driven by means of a coal planer traction chain, and the coal planer traction chain can pass through a coal planer with a driving device. The drive sprocket of the drive station of the traction chain is driven and deflected at the deflection sprocket of an especially non-driven deflection station. Background technique [0002] In modern coal plowing equipment, usually a coal plow chain is reciprocated reversing...
