Description

Technical Field

[0001] The present invention relates to the technical field of filling mining in mining engineering, and specifically relates to a carbon emission accounting device and a carbon emission accounting method applicable to underground mine stopes. Background Art

[0002] At present, "carbon emission accounting" has been gradually promoted to the daily work content of mine enterprises in China. When a large number of mines conduct carbon emission accounting, they will adopt the "top-down" accounting method, which is relatively macroscopic and is beneficial to mine planning. However, due to the large mining intensity and complex carbon emission sources in underground mines, there is currently no effective way to reasonably calculate carbon emission data for each stope and section. Only approximate calculations can be used to obtain the corresponding carbon emissions of the mine. Therefore, it is necessary to consider a carbon emission accounting device that can be applied to multiple underground scenarios, which has great research significance for the carbon reduction goal of mines in China.

[0003] The defects of the prior art are as follows:

[0004] Since the device layout units are still mainly in the midsection when the current mines are statistically calculating carbon emission data, it is impossible to accurately reach the section and stope very effectively. Therefore, it is becoming more and more necessary to have a device that can conduct carbon emission accounting for a single stope. Summary of the Invention

[0005] In view of the above problems, the present invention provides a carbon emission accounting device and a carbon emission accounting method applicable to underground mine stopes, aiming to achieve visual operation of carbon emission accounting, improve convenience; conduct carbon emission accounting for a single stope, with more accurate accounting and improved calculation efficiency; ensure that carbon emission accounting can still be carried out when the device is offline, and the carbon emission differences of each stope can be seen more intuitively.

[0006] To solve the above problems, the technical solution provided by the present invention is as follows:

[0007] A carbon emission accounting device applicable to underground mine stopes includes a device main body and a high-speed capture device, wherein:

[0008] The device main body is fixedly installed on the ore wall at the stope entrance; the device main body is used to calculate and display the carbon emission data of the stope; the device main body is electrically signal-coupled to the circuit system of the stope through an electric wire; the high-speed capture device is fixedly installed on the upper part or side wall of the stope entrance side wall and is used to capture and record the entry and exit times of the vehicles entering and leaving the stope; the high-speed capture device is electrically signal-coupled to the device main body.

[0009] Preferably, the device main body includes a device housing, physical buttons, a display screen, an intelligent electricity meter, and an operation module, wherein:

[0011] A carbon emission calculation method using the carbon emission calculation device applicable to the underground mine stope described above includes the following steps:

[0012] S100. After the stope is formed, reserve the installation positions of the device main body and the high-speed capture device at the stope entrance, and electrically signal-couple the installation positions to the underground power supply system of the stope through the wire.

[0013] S200. Fix the device main body and the high-speed capture device to the installation positions respectively, and then electrically signal-couple the device main body to the high-speed capture device.

[0014] S300. During the mining process, the high-speed capture device captures and records the time when the vehicle enters the stope and the time when the vehicle exits the stope respectively, so as to obtain the working duration of the vehicle in the stope, and then send the working duration of the vehicle in the stope to the operation module.

[0015] S400. During the mining process, the smart meter counts the electric energy input into the stope through the wire, and then sends the electricity consumption in the stope to the operation module.

[0016] S500. The stope workers input the explosive consumption used in the stope through the physical button, and then send the explosive consumption to the operation module.

[0017] S600. The built-in CPU of the operation module calculates the carbon emissions generated by the incoming and outgoing vehicles, the carbon emissions generated by the electric energy machinery, the carbon emissions generated by blasting per cubic meter of rock mass, and the carbon emissions generated by the charging equipment for completing the charging of per cubic meter of rock mass respectively through the artificially preset carbon emission algorithm, and then visually displays the main carbon emissions within a certain period of time in a single stope on the display screen through the built-in GPU of the operation module.

[0018] Preferably, the carbon emissions generated by the incoming and outgoing vehicles are expressed by the following formula:

[0019]

[0020] Where: Ee3 Used to characterize the carbon emissions generated by the in-and-out vehicles, unit: kg CO 2 ; EF electric Used to characterize the latest carbon emission factor of electric energy released by the local power grid, unit: tCO 2 / kWh; T i Used to characterize the working duration of the corresponding vehicle in the stope, unit: h; W i Used to characterize the rated power of the corresponding vehicle, unit: kW; i is used to characterize the vehicle number; n is used to characterize the number of vehicles.

[0021] Preferably, the carbon emissions generated by the electric energy machinery in a single stope are expressed by the following formula:

[0022] Ee 1 = EF electric × E

[0023] Where: Ee 1 Used to characterize the carbon emissions generated by the electric energy machinery in a single stope, unit: kg CO 2 ; EF electric Used to characterize the latest carbon emission factor of electric energy released by the local power grid, unit: tCO 2 / kWh; E is used to characterize the electricity consumption, unit kWh.

[0024] Preferably, the carbon emissions generated by blasting per cubic meter of rock mass are expressed by the following formula:

[0025]

[0026] Where: Used to characterize the carbon emissions generated by blasting per cubic meter of rock mass, unit: t CO 2 / m 3 ; EF electric Used to characterize the latest carbon emission factor of electric energy released by the local power grid, unit: tCO 2 / kWh; m is used to characterize the type of mining operation in the mine, 1-3 respectively represent the development, preparatory mining and stoping operations, and corresponding selections are made; k' is used to characterize the number of rock mass types with obvious rock property differences in the mine; Used to characterize the explosive consumption per unit volume of the same type of rock mass for blasting, kg / m 3 ;

[0027] Preferably, the carbon emissions generated by the charging equipment for charging per cubic meter of rock mass are expressed by the following formula:

[0028]

[0029] Where: Used to characterize the carbon emissions generated per cubic meter of blasted rock mass, unit: tCO 2 / m 3 ; P ch Used to characterize the operating power of the charging equipment, unit: kW; V ch Used to characterize the charging rate of the charging equipment, kg / m 3 ; ρ cb Used to characterize the density of the explosive used, kg / m 3 .

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. Since the present invention can visualize the carbon emissions generated by vehicles, fixed electricity consumption and blasting in the stope through a display screen, it is convenient for stope management personnel to understand the carbon emission situation related to the stope.

[0032] 2. Since the present invention can calculate the carbon emissions of a single stope, compared with the current "top-down" calculation method of most mines, its "bottom-up" calculation method is more applicable to mines, the calculation is more accurate, and the calculation efficiency is improved.

[0033] 3. Since the present invention uses a built-in operation module for calculation, it will not affect the calculation of carbon emissions in the stope due to network problems, thus ensuring that carbon emission accounting can still be carried out when the device is offline, and ensuring the steady progress of carbon emission accounting work for each stoping unit.

[0034] 4. Since the present invention solves the problem that underground personnel need to manually calculate the carbon emissions in the stope, it enables the carbon emissions in underground mines to enter the digital calculation era, making the carbon emission calculation results more accurate and rapid.

[0035] 5. Since the calculation results of the present invention serve each installed single stope, it solves the problem that the results of each stope are equal in traditional measurement, enabling the carbon emissions between different stopes to be intuitively seen as different, which has a certain reference role for the "dual carbon" development and plan formulation of mining enterprises.

[0041] The following further clarifies the present invention in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, various equivalent modifications made by those skilled in the art fall within the scope defined by the appended claims of this application.

[0042] As Figure 1 、 2 、shown in Figure 3, a carbon emission accounting device applicable to an underground mine stope includes a device main body 1 and a high-speed capture device 4, wherein:

[0043] The device main body 1 is fixedly installed at the ore wall at the stope entrance; the device main body 1 is used to calculate and display the carbon emission data of the stope; the device main body 1 is electrically signal-coupled to the circuit system of the stope through the electric wire 5; the high-speed capture device 4 is fixedly installed on the upper part of the side wall or the side wall of the stope entrance for easy vehicle identification, and is used to capture and record the entry and exit times of the vehicles entering and leaving the stope; the high-speed capture device 4 is electrically signal-coupled to the device main body 1.

[0044] It should be noted that the device main body 1 includes a device housing 2, a physical button 3, a display screen 6, an intelligent electricity meter 7 and an operation module, wherein:

[0045] The device housing 2 is used to fixedly install the device main body 1 and protect the internal circuit of the device main body 1; the physical button 3 is used to input the explosive consumption used in the stope; the intelligent electricity meter 7 is electrically signal-coupled to the circuit system of the stope through the electric wire 5 and is used to record the electricity consumption inside the stope during mining; the operation module is used to calculate the carbon emissions of the stope; the operation module is electrically signal-coupled to the physical button 3, the intelligent electricity meter 7 and the display screen 6 respectively; the display screen 6 is used to visually display the carbon emission calculation result of the operation module.

[0046] It should be noted that the present invention uses unified underground power supply, captures the vehicles entering and leaving the stope, and then determines the working time of the vehicles in the stope. By calculating with their rated power, the carbon emissions generated by the vehicles in the stope can be obtained. At the same time, the intelligent electricity meter 7 built into the device can count the electricity used in the stope. Thus, the carbon emissions generated by the vehicles and fixed electricity consumption in the stope are visualized through the display screen, which is convenient for the stope management personnel to understand the relevant carbon emission situation of the stope.

[0047] It should be further noted that the device main body 1 is installed on the ore wall at the stope entrance according to the operable height of personnel. After the device main body 1 is installed, the externally connected high-speed capture device 4 is connected to the device main body 1, and finally the capture ability for the vehicles entering and leaving the stope is formed.

[0048] A carbon emission accounting method using a carbon emission accounting device applicable to underground mine stopes includes the following steps:

[0049] S100. After the stope is formed, reserve the installation positions of the device main body 1 and the high-speed capture device 4 at the stope entrance, and electrically couple the installation positions to the underground power supply system of the stope through the wire 5 to ensure that the device main body 1 and the high-speed capture device 4 can statistically analyze relevant data without affecting the internal work of the stope.

[0050] S200. Fix and install the device main body 1 and the high-speed capture device 4 to their installation positions respectively, and then electrically couple the device main body 1 to the high-speed capture device 4; after the devices are installed, connect the power to the intelligent electricity meter 7 built into the device.

[0051] S300. During the mining process, the high-speed capture device 4 captures and records the time when the vehicle enters the stope and the time when the vehicle leaves the stope respectively, and then obtains the working duration of the vehicle in the stope, and then sends the working duration of the vehicle in the stope to the operation module.

[0052] S400. As Figure 4 shown, during the mining process, the intelligent electricity meter 7 statistically analyzes the electric energy input into the stope through the wire 5, and then sends the electricity consumption in the stope to the operation module.

[0053] S500. The stope workers input the explosive consumption used in the stope through the physical button 3, and then send the explosive consumption to the operation module.

[0054] S600. The built-in CPU of the operation module calculates the carbon emissions generated by the incoming and outgoing vehicles, the carbon emissions generated by the electric energy machinery, the carbon emissions generated by blasting per cubic meter of rock mass, and the carbon emissions generated by the charging equipment for completing the charging of per cubic meter of rock mass respectively through the artificially preset carbon emission algorithm, and then visualizes and displays the main carbon emissions within a certain period of time in a single stope on the display screen 6 through the built-in GPU of the operation module.

[0055] It should be noted that the carbon emissions generated by the incoming and outgoing vehicles are expressed by Equation 1:

[0056]

[0057] Where: Ee 3 is used to represent the carbon emissions generated by the incoming and outgoing vehicles, unit: kg CO 2; EF electric Used to represent the latest electricity carbon emission factor released by the local power grid, unit: tCO 2 / kWh; T i Used to represent the working duration of the corresponding vehicle in the stope, unit: h; W i Used to represent the rated power of the corresponding vehicle, unit: kW; i is used to represent the vehicle number; n Used to represent the number of vehicles.

[0058] It should be noted that the carbon emissions generated by the electric machinery in a single stope are expressed by Equation 2:

[0059] Ee 1 = EF electric × E (2)

[0060] Where: Ee 1 Used to represent the carbon emissions generated by the electric machinery in a single stope, unit: kg CO 2 ; EF electric Used to represent the latest electricity carbon emission factor released by the local power grid, unit: tCO 2 / kWh; E is used to represent the electricity consumption, unit kWh.

[0061] It should be noted that the carbon emissions generated by blasting per cubic meter of rock mass are expressed by Equation 3:

[0062]

[0063] Where: Used to represent the carbon emissions generated by blasting per cubic meter of rock mass, unit: tCO 2 / m 3 ; EF electric Used to represent the latest electricity carbon emission factor released by the local power grid, unit: tCO 2 / kWh; m is used to represent the type of mining operation in the mine, 1 - 3 represent the development, preparatory mining, and stoping operations respectively, and corresponding selections are made; k' is used to represent the number of rock mass types with obvious rock property differences in the mine; Used to represent the explosive consumption per unit volume of the same type of rock mass for blasting, kg / m 3 ;

[0064] It should be noted that the carbon emissions generated by the charging equipment for charging per cubic meter of rock mass are expressed by Equation 4:

[0065]

[0066] Where: Used to represent the carbon emissions generated by blasting per cubic meter of rock mass, unit: t CO 2 / m 3 ; P ch Used to characterize the operating power of the charging equipment, unit: kW; V ch Used to characterize the charging rate of the charging equipment, kg / m 3 ; ρ ch Used to characterize the density of the explosive used, kg / m 3 .

[0067] It should be noted that the present invention can calculate the carbon emissions of a single stope. Compared with the current "top-down" calculation method of most mines, its "bottom-up" calculation method is more applicable to mines, with more accurate calculation and improved calculation efficiency.

[0068] At present, most mines mostly use the "top-down" macroscopic calculation method, that is, before actual production, the carbon emissions in the underground are calculated and estimated in advance according to past experience in the production plan. However, the mechanical use in the stope is complex, and there will be phenomena such as early use and extra use in each stoping unit, which will result in the situation where the actual carbon emissions and the planned carbon emissions cannot correspond, causing great difficulties for on-site production personnel to actually master the on-site carbon emissions. After installing this device, the power consumption and vehicle entry and exit in the stope can be directly mastered, and the corresponding carbon emissions generated can be obtained according to the built-in calculation method, which is convenient for production personnel to master the actual situation.

[0069] It should be further noted that the present invention can dynamically monitor the relevant carbon emissions in the stope on the stope site, solving the problem that carbon emissions cannot be viewed on-site. The device uses built-in calculation software for calculation, and will not affect the carbon emissions calculation in the stope due to network problems, ensuring that carbon emissions can still be calculated when the device is offline, and ensuring the steady progress of the carbon emissions calculation work for each stoping unit.

[0070] It should be further noted that the present invention solves the problem that underground personnel need to manually calculate the carbon emissions in the stope, bringing the carbon emissions of underground mines into the digital calculation era, making the carbon emissions calculation results more accurate and rapid; its calculation results serve each installed single stope, avoiding the problem that the carbon emissions results of each stope are set to be equal in traditional measurements, enabling the carbon emissions between different stopes to be intuitively seen to be different, and having a certain reference role for the "dual carbon" development and "planning" formulation of mining enterprises.
