Description

A top coal gangue interface identification test system

Technical field

The invention relates to a roofing coal gangue interface identification test system, and belongs to the technical field of coal gangue interface identification in top coal mining.

Background technique

Coal is in a dominant position in China's energy, and it is related to the development of national industry and agriculture, and plays a pivotal role in the entire national economy. The development of coal mining technology is an important measure to increase the rate of coal mining and an important means to increase coal production. At the same time, coal mining automation is conducive to improving workers' working conditions, reducing personal injury and death, and improving labor productivity. Thick coal seams account for about 44.8% of China's total coal reserves. A considerable part of the nearly 3 billion tons of coal is mined by top coal. Therefore, the research and promotion of top coal technology is particularly important for the development of China's coal industry. The meaning. At present, in the process of fully mechanized top coal caving mining, the top coal caving mainly relies on manual visual inspection to judge the control. Due to the large dust and poor conditions of the coal mining face, it brings safety problems to the operators on site, and it is difficult to accurately judge the top. The degree of coal release will inevitably lead to over-discharge and de-discharge of the coal-splitting process. How to determine the coal-release time of the coal-filling port according to the degree of coal caving is a difficult problem encountered in the mining process of fully mechanized caving mining. As the production of coal mining face increases, it is necessary to increase the speed of hydraulic support shifting. The method of manually controlling the opening and closing of the coal inlet is no longer suitable for the operation of the electro-hydraulic caving coal support. The automatic identification of coal gangue interface is the basis for automatic control of coal mine opening and closing and top coal mining automation, which has become a basic issue in the coal production process.

At present, the research on automatic identification method of coal gangue in the process of top coal caving is mostly in the field of ray identification and image recognition, and its recognition efficiency is low, and the on-site interference factor is large. Although both coal and vermiculite belong to rock, their physical properties are quite different. When the hydraulic support is hit, different vibration response signals are generated. If these vibration response signals are used, scientific methods are used to distinguish them. It can be used to provide a new idea for the identification of coal gangue in top coal mining. In recent years, some domestic scholars have carried out research on the identification method of coal gangue interface based on tail beam vibration signal, and achieved very effective results. Through signal processing and feature extraction, it has been able to accurately identify coal gangue interface in the laboratory. However, there is still a big gap between the actual engineering application and the identification method is not perfect. At the same time, due to the lack of relevant theories, the theoretical development of coal gangue identification based on data analysis and the practical application of coal blast identification technology are severely restricted. In order to clearly understand the essential causes of signal generation under various field conditions and the true propagation law, in the research process, it is necessary to quantitatively analyze the vibration characteristics of rock and coal impact tail beam, but there is no reasonable experimental device at this stage. Used to validate and aid research.

The group particle discharge box of the combination of the box combination plates 25 has a certain distance from the multi-particle coal discharging assembly 201 to prevent mutual interference between the components. Then, the lifting device sliding chassis 29 is slid to the designated position on the multi-particle coal discharging device support slide 102, and the net tooth anti-slip bar 32 is deep down to the surface of the surface of the anti-slip tooth pressing the upper surface of the system base 1, and the vibration table is selected.

The plate 127 is in contact with the belt transport skid 114 (the contact here is not the actual contact, there is a very small gap between the two because the belt transport skid 114 needs to be rotated to prevent friction and damage), and then the belt transport slips. Machine 114 starts up on it The slide machine is arranged to gradually slide the top coal hydraulic support 70 from the belt transport slip machine 114 to the bracket mounting plate 127. During the sliding process, the two sets are supported by the bracket, the first lifting rod 115, and the bracket pushing the second. The lifting rod 116, the bracket shifting hand first shifting rod 117, the bracket pushing hand second shifting rod 118, the two-way shifting block 119, the hydraulic bracket shifting the hand block, and the topping coal hydraulic support 70 on both sides of the top coal hydraulic support 70 The clamping of 70 ensures that it slides linearly from the belt transport skid 114 to the bracket mounting plate 127. When the top coal hydraulic support 70 is about to be separated from the belt transport slip machine 114, it no longer pushes the top coal hydraulic support 70. At this time, the belt transport slip machine 114 is again fixed on the bracket transfer main board 113. The bracket mounting plate 127 and the belt transport slip machine 114 are pushed away by the belt transport sliding machine push-pull cylinder 120. At this time, the two sets are supported by the bracket first lifting rod 115, the bracket pushing hand second lifting rod 116, and the bracket. The hydraulic support of the first hand shifting lever 117, the second shifting lever 118 of the bracket, and the two-way shifting block 119 are further moved to the sides of the top coal hydraulic support 70 to be clamped, and the other set is moved by the bracket.

The other movable parts of the device 403 are moved to the tail beam portion of the top coal hydraulic support 70, and the distance between the two longitudinally linked buckle slide bars 96 is adjusted such that the inner side of one set of the buckle body plate 98 is aligned with the front end space of the top beam, and the other The inner side surface of the group main body board 98 is aligned with the end of the tail beam, and then the second crimping main board 97 is dropped along the main body board 98 to the two sets of the second pressing main board 97, respectively, which are connected to the front end of the top end of the top beam and the end of the upper end surface of the tail beam. . Then, the control system automatically calculates the distance between the inner end faces of the two main body plates 98 and calculates how many sets of the demolition sub-packages 99 and the diffusing and sub-packing plate 100 are required to be filled, and then automatically controls the seizure and dispersing plates 99 to slide along the traverse buckle slides 95. The two side faces of the side dispensing baffle composed of the plurality of sets of the seizing and unloading plates 99 are aligned with the inner end faces of the two main body plates 98, and the rear sliding sliding bar 95 slides along the vertical sliding grooves on the longitudinally-moving and sliding sliding bars 96. The distance to the inner side of the opposite side split baffles of the two groups is aligned with the two sides of the top coal hydraulic support 70, and then the respective sets of the diffuser sub-step plates 100 are slid along the sequestration sub-plate 99 to the diffusing point. The lower end of the stepped plate 100 is in contact with the upper end surface of each component of the top coal hydraulic support 70. Thus, the second crimping main plate 97, the seizing main plate 98, the seizing and unloading plate 99, and the diffusing and packing step plate 100 constitute a coal containing coal. The coal shovel is stored in the box. By controlling the height position of the second sliding card plate 93 at the support column 83, combined with the height of the top coal hydraulic support 70, the capacity of the coal sump storage box constituting the coal slag can be controlled, and the slag storage can also be changed. The amount of coal gangue stored in the tank is adjusted to reduce the amount of coal gangue. After the coal sump storage box is adjusted, the coal shovel is transported to the coal sump storage box by the coal shovel conveying device 401, and then the sliding squeegee 84 drives the fixed single groove plate 85 to slide upward, thereby driving the imitation ore loading device 402.

If it is necessary to continue to load a uniform pressure on the upper surface of the coal gangue, the single-cylinder pressure plate 89 is continuously pressed down to the set pressure value. If not, the upper end surface of the coal gangue forms a plane and then the single-cylinder pressure tank rod is retracted. 88.
