[0002] With the continuous improvement of the mechanization level in the coal mining industry, the electricity consumption in coal mines has been increasing year by year. Since electric power resources are important energy sources related to people's livelihood, the coal mining face consumes a large amount of electricity. Saving electricity can reduce the cost expenditure of enterprises and improve economic benefits. However, in traditional mechanized coal mining faces, the working face transportation system in the fully-mechanized coal flow (including shearer, scraper conveyor, transfer conveyor, belt conveyor) operates at a constant power, resulting in a huge consumption of electric power resources, a large amount of useless work, and serious waste.

Brief Description of the Drawings

[0030] In order to more clearly illustrate the technical solutions of the present application, the drawings required for use in the embodiments will be briefly introduced below. Obviously, for those of ordinary skill in the art, other drawings can also be obtained based on these drawings without creative efforts.

[0031] Figure 1 It is a schematic flow chart of the speed regulation method provided by the embodiment of the present invention. Detailed Embodiments

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Figure 1 It is a schematic flow chart of the speed regulation method provided by the embodiment of the present invention. As Figure 1 shown, it includes:

[0034] Obtain the position information of the shearer; among them, the position information acquisition can locate the position of the shearer and feed the positioning information back to the system in real time, and the position information can reflect the workload of the shearer in real time.

[0035] Obtain the running direction of the shearer; when the shearer enters the coal mining roadway, it means that the coal mining work is about to start, and when the shearer's direction exits the coal mining roadway, it means that the coal mining work is about to end.

[0036] As another solution, an infrared transmitter is installed on the body of the shearer, and an infrared receiver is provided on each hydraulic support. The position information and the running direction of the shearer emitted by the infrared transmitter are received by the infrared receiver.

[0037] Obtain the running speed of the shearer;

[0038] As another solution, obtaining the running speed of the shearer includes:

[0039] Before starting the coal mining work, set the running speed range value for the shearer to cut coal downward and the running speed range value for the shearer to return and clean the floating coal.

[0040] As another solution, when the operating speed of the shearer is within the range value of the downward coal cutting operating speed, increase the transportation speeds of the scraper conveyor and the loader; when the operating speed of the shearer is within the range value of the return journey for cleaning floating coal, decrease the transportation speeds of the scraper conveyor and the loader.

[0041] Obtain the operating status of the support hydraulic system;

[0042] Judge whether the shearer is cutting coal downward or returning for cleaning floating coal according to the position information, operating direction and operating speed;

[0043] If it is cutting coal downward, increase the transportation speeds of the scraper conveyor and the loader;

[0044] If it is returning for cleaning floating coal, decrease the transportation speeds of the scraper conveyor and the loader.

[0045] Each cycle of the shearer cutting coal is mainly divided into two parts: one is the shearer cutting coal downward. At this time, the coal volume is large, and the transportation volume of the conveyor and the loader should also increase accordingly, and the operating speed becomes faster. The other is when the shearer cuts through and returns. The shearer cleans the floating coal, and the generated coal volume is small. The scraper conveyor and the loader do not need to run at full speed and can run at a low speed according to the coal volume situation. As another solution, it also includes: an ultrasonic position sensor installed between the loader and the conveyor, and the ultrasonic position sensor detects the coal volume information of the conveyor.

[0046] As another solution, obtain the position information of the shearer before the start of coal mining work; obtain the operating direction, speed information and operating speed after the start of coal mining work.

[0053] The first processing module: if it is cutting coal downward, increase the transportation speeds of the scraper conveyor and the loader;

[0054] The second processing module: if it is returning for cleaning floating coal, decrease the transportation speeds of the scraper conveyor and the loader.

[0058] The speed regulation method and system adopted by the intelligent fully-mechanized coal mining face take the operating state of the shearer as the basic condition to adjust the operating speeds of the conveyor and the transfer machine, so that the conveyor and the transfer machine do not operate at a given power, avoiding power consumption.
