Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting an operation speed of a coal flow transportation system according to another embodiment of the present application. As shown in fig. 2, a method for adjusting an operation speed of a coal flow transportation system according to an embodiment of the present application includes:
s201, determining a first coal output state of the fully mechanized mining face based on the collected multiple regional images of the fully mechanized mining face.
S202, adjusting the running speed of the gate belt corresponding to the fully mechanized coal mining face based on the first coal outlet state.
S203, determining a second coal output state of the tunneling working face based on the collected multiple regional images of the tunneling working face belonging to the same mining area with the fully mechanized mining working face.
In the step, a plurality of regional images of the tunneling working face belonging to the same mining area as the fully mechanized mining working face are determined, and a second coal output state of the tunneling working face in the appearing stage is determined according to analysis of the plurality of regional images.
Here, since the coal produced by the fully mechanized coal mining face and the coal produced by the heading face are both transported by the mining area belt, the adjustment of the operation speed of the mining area belt in the coal flow transportation system needs to be determined by combining the first coal output state of the fully mechanized coal mining face and the second coal output state of the heading face.
S204, adjusting the running speed of a mining area belt of the mining area based on the first coal outlet state and the second coal outlet state.
In the step, the running speed of the belt in the mining area is correspondingly adjusted according to the first coal outlet state of the fully mechanized mining face and the second coal outlet state of the tunneling working face.

In the step, when a first coal outlet state is detected according to the multiple area images, the coal mining machine enters an end area from the middle area of the fully mechanized coal face, the coal mining machine is about to cut coal at two ends of the fully mechanized coal face, the coal outlet amount of the fully mechanized coal face is greatly reduced, and at the moment, the running speed of the crossheading belt needs to be reduced; when the first coal output state is detected according to the multiple regional images, the coal mining machine enters the middle region from the end region of the fully mechanized coal face, the coal cutting of the coal mining machine at the end of the fully mechanized coal face is finished, the coal output of the fully mechanized coal face is about to be normal, and at this time, the running speed of the adjustment gate belt needs to be increased to adapt to the increase of the coal output.
Here, the adjustment speed may be determined in combination with the comprehensive collection of the coal cutter position (coal cutter end cutting, coal cutter middle cutting) in the working area and the change in the amount of coal affected by the coal cutter operation speed (coal cutter middle cutting speed) in combination with the parameters (bandwidth, transportation amount, speed range) of the conveyor belt itself.

Here, when the gas concentration of the coal face reaches 1.5%, the operation must be stopped, the power supply is cut off, abnormal investigation and maintenance are performed, and after abnormal maintenance, coal mining work is performed again, so that when the gas concentration changes suddenly, the coal output of the fully mechanized coal face is reduced, and at this time, the running speed of the gateway belt needs to be properly reduced.
Further, step S204 specifically includes: when at least one of the first coal production state and the second coal production state represents a coal quantity decreasing trend, and the other one does not represent a coal quantity increasing trend, reducing the running speed of the mining area belt; when at least one of the first coal output state and the second coal output state represents a coal quantity increasing trend, and the other one does not represent a coal quantity decreasing trend, increasing the running speed of the mining area belt; when the coal mining machine enters an end area from the middle area of the fully mechanized mining face, or the coal cutting speed of the coal mining machine is reduced, the first coal output state represents a coal quantity reduction trend, and when the coal mining machine enters the middle area from the end area of the fully mechanized mining face, or the coal cutting speed of the coal mining machine is increased, the first coal output state represents a coal quantity increase trend; and when the tunneling machine is switched from tunneling to tunneling, the second coal output state represents the coal quantity decreasing trend, and when the tunneling machine is switched from tunneling to tunneling, the second coal output state represents the coal quantity increasing trend.
In the step, when one coal output state in the first coal output state and the second coal output state indicates that the coal quantity is a decreasing trend and the other coal output state does not indicate that the coal quantity is an increasing trend, controlling the running speed of a mining area belt to be reduced; and when one coal output state in the first coal output state and the second coal output state indicates that the coal quantity is an increasing trend and the other coal output state does not indicate that the coal quantity is a decreasing trend, controlling the running speed of the belt of the mining area to be increased.
When the second coal output state represents that the coal amount is about to increase, the mining area belt cannot simultaneously bear the coal output of the coal face, and the fully mechanized coal face crossheading belt needs to be controlled to completely decelerate to the belt on the upper portion of the tunneling face; and when the second coal output state representation coal amount is identified to be not increased any more, controlling the gate belt from the upper belt of the tunneling working face to the fully mechanized coal mining working face to be completely recovered to the normal speed.
Further, the adjusting method further comprises: and adjusting the running speed of the main lane belt corresponding to the mining area belt according to the speed of the mining area belt and a preset rule.
In the step, the speed of the main lane belt corresponding to the mining area belt is adjusted according to the speed of the mining area belt and a preset rule.
Here, a preset mapping relation exists between the operation speeds of the mining area belt and the main lane belt, and the operation speed of the main lane belt can be adjusted according to the operation speed of the mining area belt.
The preset mapping relationship may be set according to historical operating data or device parameters, and the present application is not limited specifically.
