Embodiment Construction
[0033] The embodiments will be described in detail hereinafter, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following examples do not represent all implementations consistent with this application. These are merely examples of systems and methods consistent with aspects of the present application as recited in the claims.
[0034] see Figure 1 to Figure 3 .
[0035] The application provides a coal mining method that can cope with multiple support situations, including the following steps:
[0036] The shearer 2 cuts coal, and the shearer 2 feeds the coal in an oblique cutting manner according to the cutting distance corresponding to the shearer 2, and transports the cut coal to the scraper conveyor 1;
[0037] The frame moving machine 3 determin...

The invention relates to a coal mining method capable of dealing with multiple supporting and protecting situations. The coal mining method comprises the following steps of cutting coal by using a coal mining machine, feeding a cutter for cutting the coal by the coal mining machine, and conveying the cut coal body to a scraper conveyer; determining the travelling speed of the coal mining machine by a frame moving machine by sensing the speed of the coal mining machine passing through the frame moving machine; making the frame moving machine in position, enabling the frame moving machine closeto the direction of the coal mining machine along the moving direction of the coal mining machine according to the travelling speed of the coal mining machine; arranging a plurality of the frame moving frames in the length direction of the scraper conveyer; and supporting and protecting by using the frame moving machines, namely, performing real-time supporting and protecting on a working surfaceafter coal is cut on one side, far away from a coal wall of the working surface, of the coal mining machine, wherein the supporting and protecting at least comprises top layer supporting and protecting. The coal mining method capable of dealing with the multiple supporting and protecting situations realizes the function of automatically adjusting the posture of the frame moving machines; differentmachine following modes can be adopted according to the changes of the speeds of the coal mining machine; and the different machine following modes can be adopted when a scraper on the working surface slides up and down.
Description
technical field [0001] The application relates to the technical field of coal mining, in particular to a coal mining method that can cope with various support situations. Background technique [0002] Intelligent mining of coal mining face is a major trend in the development of modern coal mining technology. How to realize the intelligent follow-up movement of hydraulic supports for gently inclined working faces. Ensuring the continuity of intelligent mining is a major technical issue of intelligent mining. [0003] With the existing automated mining technology, there is only a simple down-shift-up action for a single stand with the machine, and there is no mode of moving and adjusting the stand, and most of the stand posture adjustments require manual intervention. For the moving process of the whole working face, only the position of the coal machine displayed by the support is used to trigger the moving frame. There are no modifications to the shift mode based on site c...
