Mining system and mining method for high-dipping super-high seam shortwall working face

Abstract

The invention discloses a mining system and a mining method for a high-dipping super-high seam shortwall working face. The mining system comprises a coal cutter, an operating floor for controlling the coal cutter, a coal seam data acquisition subsystem for acquiring coal seam roof change data according to the geological condition of the working face, and a main control computer. The mining method comprises the steps of acquiring reference trajectory data of a rocker arm in a primary circulation coal mining working process of the coal cutter by the operating floor; acquiring the coal seam roof change data according to the geological condition of the working face by the coal seam data acquisition subsystem; receiving the reference trajectory data and the coal seam roof change data by the main control computer, and calculating planned trajectory data of the rocker arm according to the reference trajectory data and the coal seam roof change data; receiving the planned trajectory data by the operating floor, and controlling the coal cutter to perform mining operation according to the planned trajectory data. The mining system and the mining method can automatically adapt to geological condition change, and are also suitable for the high-dipping super-high seam shortwall working face.

Description

technical field [0001] The invention relates to the technical field of automatic coal mining, in particular to a mining system and a mining method suitable for short-wall working faces of steeply inclined extra-thick coal seams. Background technique [0002] At present, most coal mines use double-drum electric traction shearers, which have the automatic function of memory cutting, that is, the workflow in which the driver of the shearer operates the shearer to manually carry out a cycle of coal mining along the coal seam of the working face is the demonstration knife. (or called the reference knife), the control system uses the mining height positioning system and position positioning system to store the information such as the position, direction and speed of the shearer, and the height of the rocker arm into the controller, and then forms a shearer cut-off through data analysis and processing. The cutting track is recorded in the memory of the shearer, which provides the b...

AI Technical Summary

Problems solved by technology

[0005] 1) It can only record the fixed cutting track of the rocker arm, and the data cannot be changed, so this technology can only be used when the geological changes of the working face are small

It cannot be applied when the geological change conditions are large, resulting in the failure of the automatic function

[0006] 2) Due to the short working face of steeply inclined and extremely thick coal seams, the long-walled ordinary double-drum shearer used in the prior art cannot be applied to the mining of steeply inclined and extremely thick coal seams
