Abstract
Description
Technical Field
[0001] This invention relates to the field of data processing technology, and in particular to a method for determining the train configuration of shuttle mine cars used in TBM tunnels with small turning radii. Background Technology
[0002] The determination of the shuttle car train configuration for TBM tunnels with small turning radius refers to determining the composition and quantity of shuttle car trains based on factors such as the properties of the rock debris, vehicle parameters, and track conditions when transporting rock debris generated during tunnel excavation. This method can ensure the safe and efficient operation of shuttle car trains while also making rational use of resources. Different types of rock debris vary in weight, density, and morphology, all of which affect train operation. Improper train formation can lead to uneven load distribution, vehicle instability, slow speed, and low debris removal efficiency, increasing the risk of accidents and reducing TBM tunneling efficiency. A reasonable train formation can reduce various unsafe and unreasonable factors, ensuring smooth and efficient train operation. During TBM tunneling, rock debris needs to be removed from the tunnel as quickly as possible to ensure TBM efficiency. Improper train formation can increase vehicle resistance and extend TBM downtime, affecting the overall project progress. A reasonable train formation can reduce vehicle resistance and increase debris removal speed, thereby improving TBM tunneling efficiency. Different types of rock debris vary in quality and quantity, while train loading capacity is limited. A reasonable train formation allows for the determination of loading capacity and locomotive configuration based on rock debris properties and vehicle parameters, improving debris removal efficiency, accelerating construction progress, and enhancing project economic benefits. Therefore, it is of great significance to scientifically and rationally determine the train formation configuration of shuttle mine cars.
[0003] Currently, in TBM tunneling construction, long-distance straight-line muck removal primarily utilizes continuous belt conveyors, with shuttle car muck removal being less common. However, continuous belt conveyors are unsuitable for TBM tunnel construction with small turning radii, necessitating the use of shuttle car train formations for muck removal. However, the determination of shuttle car train formation configurations has historically relied on experience, with adjustments made only when the configuration fails to meet requirements. This results in low accuracy in shuttle car train formation configurations, leading to low efficiency in both muck removal and TBM tunneling. Therefore, a more accurate method for determining shuttle car train formation configurations for TBM tunnels with small turning radii is urgently needed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0039] Mine car train formations can be used in the tunneling of TBMs in the gravity drainage tunnels and drainage corridors of pumped storage power stations for muck removal. Muck removal during TBM tunneling is mainly divided into two stages: in the straight sections of the gravity drainage tunnel, continuous belt conveyors are primarily used for muck removal during TBM tunneling; after the TBM tunnels to the small bends and the drainage corridor connected to the gravity drainage tunnel, a combination of mine cars and continuous belt conveyors is used for muck removal. The main muck removal process is as follows: the broken rock cuttings from the TBM enter the No. 1 belt conveyor from the cutterhead chute, are transported to the No. 2 belt conveyor, and then to the shuttle mine cars via the No. 3 belt conveyor; the shuttle mine cars transport the rock cuttings to the existing continuous belt conveyor in the straight section; the rock cuttings are then transferred to the continuous belt conveyor; the continuous belt conveyor then transports the rock cuttings outside the tunnel; finally, dump trucks transport them to the spoil disposal site.
[0040] During TBM tunneling, a suitable location needs to be selected as the transfer point between the shuttle car and the continuous conveyor belt for slag removal before the gravity drainage tunnel enters the small bend section, so that the rock slag can be smoothly transferred from the shuttle car to the continuous conveyor belt. To meet the requirements of continuous TBM tunneling, the shuttle car layout scheme must not only consider the needs of slag receiving and removal, but also ensure the need for uninterrupted slag storage and transportation to meet the requirements of continuous TBM tunneling construction. Therefore, this application provides a method for determining the configuration of shuttle car train formations, thereby achieving continuous TBM tunneling construction through the configuration of shuttle car train formations.
[0041] Figure 1 A flowchart illustrating a method for determining the train formation configuration of shuttle mine cars for small-turning-radius TBM tunnels according to an embodiment of the present invention is shown. The method includes:
[0042] S101 calculates the amount of slag discharged per tunneling cycle by using the obtained rock debris loosening coefficient, tunnel excavation radius, and TBM per tunneling cycle length.
[0043] In some embodiments, the amount of slag discharged per tunneling cycle Q of the TBM s The calculation formula can be:
[0044] Q s =kπr 2 l,
[0045] Where k is the rock debris loosening coefficient; r is the tunnel excavation radius in meters; and l is the length of each tunneling cycle of the TBM in meters.
[0046] S102, based on the amount of slag discharged per tunneling cycle of the TBM and the slag capacity of the shuttle car, calculate the configuration information of the number of shuttle cars in the shuttle car train formation.
[0047] S103, obtain the rock slag density and water content coefficient.
[0048] In some embodiments, obtaining the rock debris density and water content coefficient can be performed through the following steps: collecting representative rock debris samples by drilling, excavation, or other sampling methods, ensuring that the selection of sampling points represents the characteristics of the entire ore body; sending the collected samples to a laboratory for analysis, including measuring the density and water content of the rock debris; measuring the density of the rock debris using appropriate density measuring instruments and methods, common density measurement methods include gas displacement method, liquid displacement method, and gravimetric method, etc., calculating the density value of the rock debris by measuring the mass and volume of the sample; and using a suitable method to measure the water content of the rock debris, which, depending on the specific sample characteristics, can be selected as gravimetric method, drying method, or titration method. Measurement methods such as electronic balance are used. These methods can calculate the percentage of water content by comparing the initial weight of the sample with the weight after removing moisture. Based on the density and water content data of the rock slag obtained from laboratory analysis, the water content coefficient is calculated. Generally, the water content coefficient refers to the ratio between the water content of the rock slag and its density in the dry state. This coefficient can be calculated by dividing the water content of the rock slag by its density in the dry state. The data obtained from collection and experimental analysis are analyzed to verify their accuracy and reliability, ensuring that the sample collection and experimental process comply with scientific standards and methods. At the same time, the data are repeated for testing and comparison to improve the credibility of the results.
[0049] S104, calculate the rock slag density, water content coefficient, tunnel excavation radius and TBM per tunneling cycle length to obtain the total weight of the shuttle car fully loaded.
[0050] In some embodiments, the formula for calculating the total weight W of the fully loaded mine car can be:
[0051] W=λπr 2 lρ
[0052] Where ρ is the density of the rock slag, in kg / m³. 3 λ is the moisture content coefficient.
[0053] S105 calculates the obtained slope resistance coefficient, shuttle car train formation resistance coefficient, and shuttle car train formation safety factor to obtain the total traction force required for shuttle car train formation.
[0054] In some embodiments, the formula for calculating the total traction force F required for the shuttle car train formation can be:
[0055] F=K(μ1+μ2)W
[0056] Where K is the safety factor for shuttle train operation; μ1 is the gradient resistance factor; and μ2 is the resistance factor for shuttle train operation.
[0057] S106. Based on the total traction force and adhesion coefficient, the adhesion weight configuration information of the shuttle car train group is calculated.
[0058] In some embodiments, the formula for calculating the adhesive weight configuration information G of the shuttle car train group can be:
[0059]
[0060] Where μ3 is the adhesion coefficient.
[0061] In some embodiments, the method further includes: determining the locomotive model information based on the adhesive weight configuration information. According to embodiments of the present invention, determining the locomotive model through adhesive weight configuration information ensures that the selected locomotive has sufficient traction to meet the train's traction requirements, avoiding inefficiency or safety hazards caused by insufficient or excessive traction. Selecting a suitable locomotive model can improve train traction efficiency while ensuring safety. Scientific and rational selection of the locomotive model can reduce energy consumption, decrease maintenance costs, and improve equipment utilization.
[0062] In some embodiments, the method further includes: obtaining the first time when the shuttle car train group runs to the target transfer point after being fully loaded, the second time when the shuttle car train group transfers rock slag to the continuous belt conveyor, and the third time when the shuttle car train group returns from the transfer point after being unloaded; determining whether the shuttle car quantity configuration information meets preset conditions based on the first time, the second time, the third time, and the tunneling cycle time of the TBM; if not, updating the shuttle car quantity configuration information. According to embodiments of the present invention, by acquiring the first time when the shuttle car train reaches the target transfer point after being fully loaded, the second time when the rock slag is transferred to the continuous conveyor belt, and the third time when it returns from the transfer point empty, the entire shuttle car transportation process can be monitored in real time. Based on this data, each link in the transportation process can be optimized and adjusted in real time to improve transportation efficiency and reduce costs. By judging the first, second, and third times, as well as the tunneling cycle time of the TBM, the shuttle car quantity configuration information can be automatically evaluated to determine whether it meets the preset conditions. Such automated judgment can reduce manual intervention, improve decision-making efficiency, and can be adjusted in a timely manner according to the actual situation. When the shuttle car quantity configuration information does not meet the preset conditions, it can be automatically updated, thereby realizing intelligent management of the shuttle car quantity configuration information. This intelligent management can better adapt to changes in the production environment, improve resource utilization, and reduce production costs. By continuously optimizing the shuttle car quantity configuration information, the TBM slag discharge requirements can be better matched, tunneling efficiency can be improved, and idle time during TBM tunneling construction can be reduced, thereby improving resource utilization, reducing construction costs, and enhancing enterprise competitiveness.
[0063] In some embodiments, determining whether the shuttle car quantity configuration information meets preset conditions based on the first time, the second time, the third time, and the tunneling cycle time of the TBM includes: calculating the total time of the first time, the second time, and the third time; if the total time is less than or equal to the tunneling cycle time of the TBM, then the shuttle car quantity configuration information meets the preset conditions; if the total time is greater than the tunneling cycle time of the TBM, then the shuttle car quantity configuration information does not meet the preset conditions.
[0064] In some embodiments, two additional shuttle cars are configured at the tail of the TBM for slag storage. The track gauge of the slag storage shuttle cars is the same as that of the TBM trolley. The slag storage shuttle cars continuously follow the TBM trolley to move forward and store slag. The shuttle car train sets up and back between the slag storage shuttle cars and the continuous belt conveyor to transport and transfer slag.
[0065] According to an embodiment of the present invention, the amount of slag discharged per tunneling cycle of the TBM is obtained by calculating the acquired rock debris loosening coefficient, tunnel excavation radius, and tunneling cycle length of the TBM; based on the slag discharge per tunneling cycle of the TBM and the slag capacity of the shuttle car, the configuration information of the number of shuttle cars in the shuttle car train formation is calculated; the rock debris density and moisture content coefficient are obtained; the total weight of the shuttle car is obtained by calculating the rock debris density, moisture content coefficient, tunnel excavation radius, and tunneling cycle length of the TBM; the total traction force required for the shuttle car train formation is obtained by calculating the acquired slope resistance coefficient, resistance coefficient of the shuttle car train formation, and safety factor of the shuttle car train formation; based on the total traction force and adhesion coefficient, the adhesion weight configuration information of the shuttle car train formation is calculated. This enables precise determination of the configuration of the shuttle car train formation, improving the accuracy of the shuttle car train formation configuration.
