As shown in fig. 1 and 10, the mining method according to the embodiment of the present invention is used for an open-air mining operation, and specifically, the mining method includes:

S101, determining a mining working face advancing direction and a mining area working face advancing direction according to mining area mineral distribution conditions, wherein the mining working face advancing direction is specifically the advancing direction of the continuous miner 8 when coal mining is carried out, and the mining area working face advancing square is the integral advancing direction of the working face of the whole mining area.

The mining face advancing direction and the panel face advancing direction are orthogonally arranged, in fig. 1, the mining face advancing direction is forward advancing or backward advancing along the front-back direction, the current mining face advancing direction is the direction a, that is, forward advancing, and the panel face advancing direction is the direction B, that is, leftward advancing along the left-right direction shown in fig. 1.

After the mining operation of the current mining face is completed, the continuous miner 8 needs to move forward or backward along the front-back direction in fig. 1 to perform the mining operation of the next mining face, and after the continuous miner 8 moves, both the transfer conveyor 9 and the receiving device need to move to ensure that the coal mined by the continuous miner 8 can be transferred onto the conveyor 7, and at this time, the conveyor 7 can temporarily not need to move in the left-right direction in fig. 1 until the mining operation of the current mining face is completed.

However, if the continuous miner 8 finishes mining of the current mining area working surface along the current a direction, the continuous miner 8 needs to move a certain distance along the mining area working surface advancing direction so as to perform mining operation of the next mining area working surface, at this time, not only the transfer conveyor 9 and the receiving device need to move correspondingly, but also the conveyor 7 needs to move a certain distance along the mining area working surface advancing direction, therefore, before each time the receiving device is moved, a part of the section of the conveyor 7 is moved transversely so as to adapt to mining operation of the next mining area working surface, or after mining operation of one mining area working surface is finished, each middle frame of the conveyor is moved transversely by the receiving device in sequence so as to adapt to mining operation of the next mining area working surface, and the direction C shown in fig. 1 is the direction in which the receiving device needs to move so as to adapt to mining operation of the next mining area working surface.

The first way is: in the mining process of the current mining area working face, when the mining area working face is switched every time, the material receiving device transversely moves a part of the middle frames in the conveyor, and finally, after the mining of the current mining area working face is finished, the conveyor also transversely moves.

The second mode is as follows: and in the process of mining the current mining area working face, the transverse movement of the conveyor is not carried out, after the mining of the current mining area working face is completed, all middle frames of the conveyor are sequentially transversely moved through the material receiving device, and finally the transverse movement of the whole conveyor is completed.

The relationship between the mining face and the panel face is: the mining face is the face of the continuous miner 8 and the panel face is the overall mining direction of one panel, so the mining face and panel face are arranged orthogonally. Along with the continuous pushing of the mining working face, the mining of one mining area working face can be completed, and along with the continuous pushing of the mining area working face, the mining of the whole mining area can be completed.

When the first mode is adopted to carry out the transverse movement of the conveyor, in order to enable the conveyor 7 to meet the operation requirement of the current mining area working surface and also meet the operation requirement of the next mining area working surface, the conveyor 7 needs to be transversely moved before the receiving device moves, so that the position of the conveyor 7 positioned behind the receiving device meets the operation requirement of the next mining area working surface, and the position of the conveyor 7 positioned in front of the receiving device meets the operation requirement of the current mining area working surface.

S104, repeating the previous step, and carrying out mining operation of the working face of the next mining area.

After the transverse movement of the conveyor is completed, the continuous miner can perform mining work of the next mining area working face

s201, the first frame 1 and the conveyor 7 are connected by the connection assembly 4.

If the connection assembly 4 needs to be reinstalled every time the conveyor 7 is moved laterally, the connection assembly 4 is installed to connect the first frame 1 and the conveyor 7, if the connection assembly 4 is always connected between the first frame 1 and the conveyor 7, frequent disassembly is not needed, and checking of alignment is needed every time the conveyor 7 is installed, so that lifting and movement of the conveyor 7 can be smoothly guaranteed.

And S202, lifting the supporting legs 23, and driving the second frame body 2 to move along the advancing direction of the mining area working face, so that a space is reserved for the movement of the first frame body 1 and the conveyor 7.

S203, driving the supporting legs 23 to prop against the ground and lifting the partial sections of the first frame body 1 and the conveyor 7, wherein after the supporting legs 23 prop against the ground, the second bracket bears the weight of the partial sections of the first frame body 1 and the conveyor 7, and as the second driving part 6 is lifted continuously, the partial sections of the first frame body 1 and the conveyor 7 are separated from the ground.

S204, driving a part of sections of the first frame body 1 and the conveyor 7 to move along the mining area working surface, putting down the first frame body 1 and enabling the conveyor 7 to prop against the ground after moving in place, specifically, driving the first driving part 5 to act, and driving the first frame body 1 to move on the second frame body 2 along the mining area working surface, wherein the conveyor 7 moves transversely along with the first frame body 1, so that the position of the conveyor 7 of the section can meet the mining operation requirement of the next mining area working surface.

The coal blocks stripped by the continuous miner arrive at the crawler conveyor from the scraper chain on the continuous miner and arrive at the belt conveyor through the material receiving device, so that a complete continuous coal mining process system of the opencut coal mine is formed. After the current mining area working face is mined, the continuous mining machine needs to move forwards and is ready to mine the next mining area working face, at the moment, the walking crawler-type transfer conveyor can walk below the scraper chain of the continuous mining machine, wherein the middle frames of the belt conveyor complete transverse movement under the action of the material receiving device, and the transverse movement of the whole belt conveyor can be finally realized along with the transverse movement of the material receiving device to each section of the conveyor so as to meet the requirement of continuous mining of the next mining area working face.

Wherein, fig. 4 shows that the left side supporting leg of the material receiving device is contracted upwards, fig. 5 shows that after the first supporting part in the second frame body of the material receiving device is extended leftwards and transversely, and the whole supporting leg on the second frame body is extended downwards, so that the middle frame and the track of the belt conveyor at the current position are separated from the ground along with the first frame body at the same time; FIG. 6 shows the first drive member on the first support on the left side beginning to retract and the first drive member on the second support on the right side beginning to extend so that the track and corresponding intermediate frame structure on the conveyor are simultaneously moved laterally to the left; FIG. 7 shows the legs of the first support and the legs of the second support retracted by the second drive member such that the track is grounded to the belt conveyor intermediate frame; FIG. 8 shows the first drive member on the second support on the right retracted to complete the second support to move to the left; fig. 9 shows the legs of the first and second support parts being extended downwardly and landing completed by the second driving means, thereby completing the lateral movement of the intermediate frame of a belt conveyor. At this time, the receiving device sequentially executes the operations of fig. 4 to 9 based on the next intermediate frame to be laterally moved, which the automatic travelling mechanism moves to along the track, thereby completing the automatic lateral movement task of the whole belt conveyor.
