The coal mining machine is used as large complex equipment integrating machinery, electricity and hydraulic pressure, and can realize mechanized coal mining operation. Because the coal mining machines of different types have respective working capacities, if an unsuitable coal mining machine is selected to finish the coal mining work of the coal mine, the coal mining work of the finished coal mine may exceed the rated working capacity of the coal mining machine, the coal mining machine cannot finish the current coal mining work of the coal mine in time, and the working efficiency of the final coal mining is affected; it is also possible that the coal mining job of the coal mine is small, the current shearer's capacity is more than sufficient to complete the current coal mining job, and the shearer's capacity is proportional to its price. If an unsuitable coal cutter is selected for the coal mine, not only is the working capacity of the coal cutter wasted, but also the cost of the coal mining work is increased. Therefore, a proper coal cutter is required to be selected according to the specific situation of the coal mine to finish the coal mining work.

The coal mining machine selected by other coal mines in the same area and nearby the coal mine is used as the coal mining machine needed to be selected by the current coal mine. However, the conditions of the coal seam and the working conditions are quite different, and the optimal coal cutter suitable for the current coal mine cannot be obtained by only relying on the coal cutter used by the nearby coal mine.

Detailed Description
For a clearer understanding of the objects, technical solutions and advantages of the present application, the present application is described and illustrated below with reference to the accompanying drawings and examples. However, it will be apparent to one of ordinary skill in the art that the present application may be practiced without these details. It will be apparent to those having ordinary skill in the art that various changes can be made to the embodiments disclosed herein and that the general principles defined herein may be applied to other embodiments and applications without departing from the principles and scope of the present application. Thus, the present application is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the scope claimed herein.
Embodiments of the present application are described in further detail below with reference to the drawings attached hereto.
When the coal mining machine is used for coal mining, the coal mining machine is matched with a conveying device and a hydraulic device. The production capacity of the coal mining machine and the conveying device can meet the production requirement of a working face, the height-adjusting range of the coal mining machine and the hydraulic device is suitable for the thickness and the variation range of a coal seam, and the moving speed of the hydraulic device is required to keep up with the traction speed of the coal mining machine. The coal mining machine is guided by and moves on a conveyor, the conveyor is pushed by a hydraulic device, and the hydraulic device is supported by the conveyor to move. In order to achieve maximum productivity and safe production of coal mining, the shearer, the conveyor and the hydraulic device need to be mutually adapted and matched. In the coal mining process, the coal mining machine is mainly used for cutting coal from a fully-mechanized coal mining face, and when one coal mining machine finishes the coal mining work of a certain coal mine, the coal mining machine can generate larger abrasion to influence the subsequent use; the hydraulic device is mainly used for attaching and supporting the fully-mechanized coal mining face, when the hydraulic device finishes the coal mining work of a certain coal mine, if the coal falls, the hydraulic device can be damaged, and if the coal does not fall, the hydraulic device is not damaged generally; the conveyor is mainly used for conveying coal from a coal mine to a fixed position, and the conveyor generally does not generate any abrasion after the coal mining work is completed. Thus, the conveyor is typically retained for subsequent use in other coal mines.
Fig. 1 is a block diagram of a coal cutter type selection method provided in this embodiment. As shown in fig. 1, a coal mining machine model selection method comprises the following steps:
step S100, acquiring the coal mining mode and geological information of the current coal mine, and acquiring primary-selection numerical primary-selection coal cutter models which simultaneously meet the coal mining mode and can efficiently mine coal in the geological information representation environment from a plurality of preset alternative coal cutter models.
At present, two coal mining modes are mainly used in China, one is wall type coal mining, the other is column type coal mining, and the specific coal mining mode is determined by the characteristics of the coal mine. If the coal mine is characterized by longer coal wall, adopting wall type coal mining; if the coal mine is characterized by shorter coal wall and square column shape, the column type coal mining is adopted when the number of working faces which can be mined simultaneously is large. The specific coal mining mode can be selected according to the geological conditions and mining budget of the coal mine, so that the requirements of safety in work, high yield, high efficiency, good coal quality, low cost, high coal recovery rate and the like are met to the maximum extent. In the embodiment, the coal mining mode of the current coal mine is determined by taking the working safety as a main requirement. The coal wall length of the underground coal wall can be obtained through a detection method, the coal wall length is compared with a preset coal wall length, and if the coal wall length is not smaller than the preset coal wall length, the current coal mining mode of the coal mine is wall type coal mining; if the coal wall length is smaller than the preset coal wall length, the current coal mining mode of the coal mine is pillar coal mining. The preset coal wall length represents the length of the wall length corresponding to the wall coal mining and the length of the column length corresponding to the column coal mining, and the preset coal wall length is obtained through a large amount of coal mining experience summary.
The coal wall length of the underground coal wall can be obtained through detection methods such as tunnel radio wave perspective method (pit penetration method for short), cao Bofa seismic exploration, geological radar method and the like. This example uses Cao Bofa seismic exploration to obtain the coal wall length. Typically, the density of the coal seam is much less than the density of the surrounding rock, and the propagation velocity of the seismic waves in the coal seam is low. Thus, coal is a significantly lower velocity trough than the surrounding rock. Since the top-bottom interfaces of the coal bed are mostly parallel, the total reflection process is repeatedly performed between the top-bottom interfaces of the coal bed, so that a special wave, namely a groove wave, which propagates along the coal bed (namely two-dimensional direction) in a remote direction is formed. A slot wave is a seismic wave that propagates only in a coal seam, also known as a coal seam wave or guided wave. The reflection and transmission of the wave will occur when the wave propagates in the coal bed and encounters the interface between two different mediums, and the position and scale of the interface can be determined by detecting the change of the wave, thereby determining the coal wall length of the underground coal wall.
The geological information comprises a maximum hardness parameter, a minimum thickness parameter and a maximum angle parameter which characterize the coal mine. In the process of obtaining the coal wall length by adopting the slot wave method seismic exploration, the shape of the coal mine can be obtained through different propagation speeds of seismic waves in the coal bed and other mineral layers, so that the angle parameter range in the geological information is obtained. In addition, after the position and the size of the coal mine are determined, the coal mine is divided into a plurality of sub-coal mines along the direction perpendicular to the thickness of the coal mine, round holes with small diameters and large depths are drilled underground in each sub-coal mine through drilling machinery, and the hardness parameters and the thickness parameters of the sub-coal mine are obtained from the inside of the holes. Selecting a maximum hardness parameter from hardness parameters corresponding to all sub-coal mines to obtain the maximum hardness parameter of the coal mine; selecting a minimum thickness parameter from thickness parameters corresponding to all sub-coal mines to obtain a minimum hardness parameter of the coal mine; the maximum value of the angle parameter range is the maximum angle parameter of the coal mine.
The production of the coal mining machine corresponding to each coal mining machine model requires the manufacturer to build a production line for production, and once the manufacturer modifies the production line into the production line of other coal mining machine models, or removes the production line corresponding to the coal mining machine model, the production line means that the coal mining machine of the coal mining machine model is not produced any more, and the situation that the coal mining machine corresponding to the coal mining machine model is eliminated is also indicated. All the coal cutter models of the production line still existing in the market are stored in the selection module, and the coal cutter models are a plurality of preset alternative coal cutter models. In order for the shearer to efficiently complete the current coal mining work of the coal mine, primary selection numerical primary selection shearer models which can simultaneously meet the coal mining mode and efficiently mine coal in the geological information representation environment need to be obtained from the alternative shearer models.
Fig. 2 is a block diagram of a method for obtaining a number of primary selection coal mining machine types with primary selection values according to the present embodiment. As shown in fig. 2, a method for obtaining a number of primary selection coal mining machine types with primary selection values includes the following steps:
step S101, obtaining an alternative coal mining mode corresponding to each alternative coal mining machine model, and sequentially judging whether each alternative coal mining mode is the same as the coal mining mode, if so, the alternative coal mining machine model corresponding to the alternative coal mining mode is a first coal mining machine model.
Step S102, if the candidate coal mining modes are different, the corresponding candidate coal mining machine model is not a first coal mining machine model.
Step S103, counting the number of all the first coal cutter models after determining whether each alternative coal mining mode is the same as the coal mining mode, and recording the number as a first numerical value.
Step S104, obtaining a technical parameter set corresponding to each first coal cutter model, and substituting the technical parameter sets into a preset calculation formula for representing the working performance of the coal cutter in sequence to obtain a first numerical value of actual working parameters for representing the working condition of the coal cutter.
Step S105, obtaining reference working parameters corresponding to the geological information through a preset geological information and reference working parameter relation table, and sequentially judging whether each actual working parameter is smaller than the reference working parameter, if not, the first coal mining machine model corresponding to the actual working parameter is a primary coal mining machine model.
And S106, if the model is smaller than the actual working parameter, the model of the first coal cutter corresponding to the actual working parameter is not the model of the primary coal cutter.
And S107, counting the number of all the primary coal mining machine models after determining whether each actual working parameter is smaller than the reference working parameter, and marking the number as a primary numerical value.
By checking a corresponding table of the model and technical information of the coal mining machine, an alternative machine weight corresponding to each alternative coal mining machine signal can be obtained, and if the alternative machine weight exceeds a preset machine weight, the alternative coal mining mode corresponding to the model of the alternative coal mining machine is wall type coal mining; if the candidate machine weight does not exceed the preset machine weight, the candidate coal mining mode corresponding to the model of the candidate coal mining machine is pillar coal mining. And comparing the alternative machine weight corresponding to each alternative coal cutter model with the preset machine weight to obtain an alternative coal mining mode corresponding to each alternative coal cutter model. The preset weight is obtained through summarizing a large amount of coal mining experience. In the corresponding table of the model of the coal mining machine and the technical information, the weight of each coal mining machine corresponding to the model of the coal mining machine is stored, the corresponding table of the model of the coal mining machine and the technical information is provided by a coal mining machine manufacturer, and the coal mining machine manufacturer outputs the model of the coal mining machine and the technical information related to the coal mining machine when producing the coal mining machine, wherein the technical information comprises technical parameters of a plurality of coal mining machines. The technical information is in one-to-one correspondence with the model of the coal mining machine.
In order to make the working mode of the coal cutter suitable for the coal mining mode corresponding to the current coal mine, the coal cutter model which has the same coal mining mode as the current coal mine coal mining mode needs to be screened out of a plurality of alternative coal cutter models. The selection module stores the number of candidates of the candidate coal cutter model, and compares each candidate coal mining mode with the current coal mining mode in sequence. When the alternative coal mining mode is the same as the current coal mining mode, adding a first character representing the current coal mining machine model as a first coal mining machine model into the coal mining machine model corresponding to the coal mining mode; when the alternative coal mining mode is different from the current coal mining mode, adding an alternative character representing that the current coal mining machine model is not the first coal mining machine model into the coal mining machine model corresponding to the coal mining mode. After each first character or alternative character is added, the first initial number is added by one to obtain a new first initial number, and the original first initial number is replaced by the new first initial number. And after the first initial number is equal to the alternative number, indicating that each alternative coal mining mode is determined, and determining the first number of the coal mining machine models marked with the first characters by checking the characters in all the coal mining machine models. Wherein the first initial number is zero before the alternative coal mining mode is not compared with the current coal mining mode of the coal mine.
Each technical parameter set comprises a plurality of technical parameters corresponding to a fixed number of fixed attributes. Each technical information contains a number of technical parameters not smaller than the number of technical parameter sets. The technical information includes, but is not limited to, the following technical parameters of the attributes: the technical parameters of the height, the depth, the traction speed, the adaptive inclination angle, the diameter, the rotation speed, the length and the swing center distance of the rocker arm are adopted. The technical parameter set comprises the technical parameters with the following attributes: a mining height technical parameter, a cutting depth technical parameter and a traction speed technical parameter. And by checking a corresponding table of the model of the coal cutter and the technical information, the technical parameter set corresponding to each first model of the coal cutter can be obtained.
In view of the time that the shearer may take necessary auxiliary operations such as mobilizing the machine, replacing the cutting pick, cutting the incision, inspecting the machine, and removing the fault during operation, the present embodiment uses the technical productivity calculation formula as the calculation formula for characterizing the working performance of the shearer, and the technical productivity calculation formula is stored in the model selection module. Wherein, the technical productivity calculation formula is that the technical productivity = coefficient x 60 x mining height skill Surgical parameters x depth of cut technical parameters x traction speed technical parameters x coal density. The density of coal is 1.3-1.4 t/m 3 In this embodiment, the coal density is 1.35t/m 3 . The coefficient characterizes the coefficient related to the reliability and completeness of the coal mining machine technology, generally 0.5-0.7, and in this implementation, the coefficient is 0.6. The actual operating parameter that characterizes the working condition of the coal mining machine in this embodiment is the technical productivity. The first numerical actual working parameters can be obtained by substituting the mining height technical parameters, the cutting depth technical parameters and the traction speed technical parameters in the technical parameter sets corresponding to each first coal cutter model into a technical productivity calculation formula.
The selection module also stores a relation table of geological information and reference working parameters, and the reference working parameters represent the minimum technical productivity which the coal mining machine should output when carrying out coal mining work. Thus, the relationship table is used to characterize the minimum technical productivity that allows the shearer output when mining in coal mines of different geological information. The geological information and reference working parameter relation table is obtained through a large amount of coal mining experience summary. And checking the relation table of the geological information and the reference working parameters to obtain the reference working parameters corresponding to the geological information of the current coal mine. The relation table stores a large number of reference working parameters corresponding to different geological information, wherein the geological information in the relation table only represents hardness parameters, thickness parameters and angle parameters corresponding to a certain coal mining point, and does not represent maximum hardness parameters, minimum thickness parameters and maximum angle parameters of the whole coal mine.
In addition, each actual operating parameter is compared in magnitude with the reference operating parameter. When the actual working parameters are not smaller than the reference working parameters, adding a primary selection character representing that the current coal cutter model is a primary selection coal cutter model into the first coal cutter model; when the actual working parameter is smaller than the reference working parameter, adding a primary character representing that the current coal cutter model is not the primary coal cutter model into the first coal cutter model.
