Description

Technical Field

[0001] This invention relates to the field of open-pit mining technology, specifically to an intelligent water spraying dust suppression system. Background Technology

[0002] Open-pit mining involves stripping away the topsoil and surrounding rock of the ore body, transporting waste rock to a spoil heap, and directly extracting ore from the exposed ore body. Open-pit mining is superior to underground mining when the ore body is shallow or has surface outcrops. The work of stripping away the topsoil and rock is called stripping. The ratio of the amount of stripped rock and rock to the amount of ore extracted is called the stripping ratio. Open-pit mines with excessively high stripping ratios have high costs and should be converted to underground mining methods. Open-pit mining is an independent production and management unit with defined mining boundaries.

[0003] The extraction and transportation of stone in mines generate a large amount of dust. This dust not only causes serious pollution to the surrounding environment, but also causes great harm to the health of workers on site and residents living nearby. Therefore, it is necessary to carry out dust suppression operations in open-pit mines.

[0004] Existing open-pit mines typically employ two main dust suppression strategies: general dust suppression and roadside water spraying. General spraying, due to the large area of ​​open-pit mines, is only effective for localized areas requiring prolonged, high-volume spraying, resulting in poor targeting and wasting water resources. Furthermore, it can easily lead to water accumulation when dust suppression demand is low. Water spraying, on the other hand, requires separate vehicles and can only provide preventative dust suppression based on possible vehicle routes or as a remedial measure after significant dust accumulation. However, this method is not timely; preventative measures often fail when dust occurs, and remedial measures often require large-volume spraying, further exacerbating the dust problem.

[0005] Based on the above problems, a dust suppression system is needed to solve them. Summary of the Invention

[0006] This invention addresses the problem that large amounts of dust are generated during the quarrying and transportation of stone in existing technologies. This dust not only causes serious pollution to the surrounding environment but also poses a significant health risk to construction workers and nearby residents. The invention provides an intelligent water spraying dust suppression system, which adopts a design framework focused on the timeliness of dust suppression to solve the aforementioned problems.

[0007] This invention provides an intelligent dust suppression system, comprising a mobile dust source suppression module, a fixed dust area suppression module, an environmental dust suppression module, and a dust control module. The dust suppression terminals of the environmental dust suppression module are evenly distributed within the open-pit mine. The dust suppression terminals of the fixed dust area suppression module are located in areas where dust is generated according to time or production patterns. The coverage area of ​​the fixed dust area suppression module terminals is smaller than that of the environmental dust suppression module. The mobile dust source suppression module terminals are mounted on moving objects entering and exiting the open-pit mine. Both the fixed dust area suppression module and the environmental dust suppression module are digitally connected to the dust control module. The mobile dust source suppression module is data-connected to each dust suppression terminal of the environmental dust suppression module within a defined range centered on each dust suppression terminal of the mobile dust source suppression module. Each dust suppression terminal of the environmental dust suppression module is equipped with a location tag.

[0008] The mobile dust source suppression module is a small-volume spray and sensor integrated structure installed on a vehicle. It can be a small device that can be installed quickly. It can be installed in real time when the vehicle enters the mining area, and work with the environmental dust suppression module to enhance the spraying around the vehicle.

[0009] The intelligent water spraying dust suppression system of the present invention, as a preferred embodiment, includes a dust suppression control module comprising a timer module, a production process dust source module, an environmental dust suppression location control module, a dust suppression degree control module, and a positioning module. The timer module is a cyclic clock, which controls the dust suppression terminal of the environmental dust suppression module to perform timed dust suppression behavior by feeding back time data to the dust suppression degree control module.

[0010] The dust source module in the production process generates a dust suppression enhancement location signal with timestamps and production attribute information in the open-pit mine by inputting the production plan, and controls each dust suppression terminal of the dust suppression module in the fixed dust area through the dust suppression degree control module.

[0011] The environmental dust suppression location control module is used to collect the location tags of each terminal of the environmental dust suppression module that have received information from each terminal of the mobile dust source dust suppression module and transmit them to the positioning module. The positioning module determines the coverage area and movement direction of each terminal of the mobile dust source dust suppression module based on the real-time location tags of each terminal of the environmental dust suppression module and sends the control signal to the dust suppression degree control module.

[0012] The dust suppression control module adjusts the dust suppression behavior of each dust suppression terminal in the mobile dust source suppression module, the fixed dust area suppression module, and the environmental dust suppression module according to different information types.

[0013] In a preferred embodiment of the intelligent water spraying dust suppression system described in this invention, the dust suppression degree control module receives time data from the timer module and then uses the dust suppression information carried in the dust suppression amount signal output by each dust suppression terminal of the environmental dust suppression module to determine the dust suppression degree as a quantitative value.

[0014] In a preferred embodiment of the intelligent sprinkler dust suppression system described in this invention, after the positioning module receives the location information transmitted by the environmental dust suppression location control module, it performs noise reduction processing on each location information to form several dust coverage areas for moving objects. Based on the real-time changes in the coverage areas of moving objects, it makes a preliminary prediction of the trajectory, speed, and affected area of ​​the moving objects. It then performs strong dust suppression enhancement on the terminals of the environmental dust suppression modules within a threshold range set in the direction of the moving objects' origin, and weak dust suppression enhancement on the terminals of the environmental dust suppression modules within a threshold range set in the direction of the moving objects' movement.

[0015] For dust patterns arising from moving objects on soil surfaces, dust suppression modes are categorized into preventative and remedial dust suppression. Preventative dust suppression is determined by the possible direction of movement of the moving object. Due to its preventative nature, its accuracy does not need to be too high. Furthermore, since the dust does not enter the affected area, its prediction range should not be too large. Remedial dust suppression, on the other hand, is determined by the moving object's path. In open-pit mines, a significant amount of dust will inevitably be generated along the path of the moving object. Since this dust is already generated, its accuracy is naturally higher. The dust suppression range should be determined based on the speed of the moving object. The faster the moving object moves, the faster the frequency of the rapid dust suppression signal should be, and the shorter the travel distance. Based on this, any terminal within the short travel distance that receives the dust suppression signal should continuously suppress dust within a specific timeframe. Furthermore, the higher the speed, the higher the degree of dust suppression indicated by the signal.

[0016] In the intelligent sprinkler dust suppression system described in this invention, as a preferred embodiment, the enhanced dust suppression degree of the strong dust suppression enhancement is greater than the enhanced dust suppression degree of the current corresponding mobile dust source dust suppression module terminal, which is greater than the enhanced dust suppression degree of the weak dust suppression enhancement.

[0017] The intelligent water spraying dust suppression system of the present invention, as a preferred embodiment, uses water spraying or water spraying and dust suction as the dust suppression method of the dust suppression terminal of the mobile dust source dust suppression module, the dust suppression terminal of the fixed dust area dust suppression module, and the dust suppression terminal of the environmental dust suppression module.

[0018] In the intelligent water spraying dust suppression system of the present invention, as a preferred embodiment, the range of strong dust suppression enhancement is determined by the moving path of the moving object, the range of weak dust suppression enhancement is determined by the tangential direction of the current movement of the moving object, and the axial length of the strong dust suppression enhancement range is greater than the axial length of the weak dust suppression enhancement range.

[0019] In a preferred embodiment of the intelligent water spraying dust suppression system described in this invention, the dust suppression degree control module forces each terminal of the environmental dust suppression module to perform dust suppression behavior equivalent to the dust suppression information and degree after receiving time data feedback from the timer module, based on the information received from the mobile dust source dust suppression module.

[0020] In a preferred embodiment of the intelligent water spraying dust suppression system described in this invention, the dust suppression degree control module controls the dust suppression at each terminal of the dust source module in the production process based on the production attribute information of the received dust suppression enhancement location signal. The dust suppression degree is a variable determined based on the production attribute information.

[0021] Based on the production process, a production map is created that changes over time. Then, based on the different production attributes, such as the different levels of dust generated by activities like perforation, blasting, and loading, different levels of dust reduction are implemented.

[0022] In a preferred embodiment of the intelligent sprinkler dust suppression system described in this invention, when the dust suppression terminal of the mobile dust source dust suppression module enters the coverage area of ​​the dust suppression terminal of the fixed dust suppression module, the dust suppression terminal of the mobile dust source dust suppression module suspends its signal connection with each dust suppression terminal of the environmental dust suppression module.

[0023] Production sites should meet the requirements for maximum dust reduction, and vehicle traffic should be taken into account in production considerations. Therefore, at fixed production locations, the impact of vehicles on dust reduction is temporarily eliminated to reduce further waste of water resources.

[0024] The present invention has the following advantages:

[0025] In open-pit mines, dust pollution primarily originates from fixed-point production and transportation activities. Fixed-point production includes activities such as drilling, blasting, and loading, which inherently generate dust at specific locations, and their dust emission patterns are predictable. Transportation activities, however, generate dust based on the movement of materials, making their dust emission more time-sensitive. This technical solution employs a targeted system that pre-sets water spraying for fixed-point dust suppression and combines it with mobile module dust suppression. The function of the water truck is split between watering the transport vehicles and the surrounding environment, reducing the overall amount of water sprayed for environmental dust suppression. Instead, the spraying volume is increased in the area affected by the transport vehicles themselves, supplemented by simple vehicle-based dust suppression, achieving a more rational water spraying dust suppression mode. This achieves a more significant dust suppression effect compared to existing methods using less water. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1

[0032] like Figure 1 As shown, an intelligent dust suppression system includes a mobile dust source suppression module 1, a fixed dust area suppression module 2, an environmental dust suppression module 3, and a dust control module 4. The dust suppression terminals of the environmental dust suppression module are evenly distributed within the open-pit mine. The dust suppression terminals of the fixed dust area suppression module 2 are set in areas where dust is generated according to time or production patterns. The coverage area of ​​the fixed dust area suppression module 2 terminals is smaller than that of the environmental dust suppression module 3. The dust suppression terminals of the mobile dust source suppression module 1 are set on moving objects entering and leaving the open-pit mine. Both the fixed dust area suppression module 2 and the environmental dust suppression module 3 are digitally connected to the dust control module 4. The mobile dust source suppression module 1 is data-connected to each dust suppression terminal of the environmental dust suppression module 3 within a set range centered on each dust suppression terminal of the mobile dust source suppression module 1. Each dust suppression terminal of the environmental dust suppression module 3 is equipped with a location tag.

[0033] like Figure 2 As shown, the dust control module 4 includes a timer module 41, a production process dust source module 42, an environmental dust control module 43, a dust control module 44, and a positioning module 45. The timer module 41 is a cyclic clock. The timer module 41 controls the dust control terminal of the environmental dust control module 3 to perform timed dust control behavior by feeding back time data to the dust control module 44.

[0034] The dust source module 42 in the production process generates a dust suppression enhancement location signal with timestamp and production attribute information in the open-pit mine by inputting the production plan, and controls each dust suppression terminal of the dust suppression module 2 in the fixed dust area through the dust suppression degree control module 44.

[0035] The environmental dust suppression location control module 43 is used to collect the location tags of each terminal of the environmental dust suppression module 3 that have received information from each terminal of the mobile dust source dust suppression module 1 and transmit them to the positioning module 45. The positioning module 45 determines the coverage range and movement direction of each terminal of the mobile dust source dust suppression module 1 based on the location tags of each terminal fed back by each terminal of the environmental dust suppression module 3 in real time, and sends the control signal to the dust suppression degree control module 44.

[0036] The dust suppression control module 44 adjusts the dust suppression behavior of each dust suppression terminal in the mobile dust source dust suppression module 1, the fixed dust area dust suppression module 2, and the environmental dust suppression module 3 according to different information types.

[0037] After receiving the time data from the timer module 41, the dust reduction control module 44 measures the dust reduction information carried by the dust reduction amount signal output by each dust reduction terminal of the environmental dust reduction module 3, and the dust reduction degree is quantitative.

[0038] After receiving the location information transmitted by the environmental dust suppression location control module 43, the positioning module 45 performs noise reduction processing on each location information to form several dust coverage areas of moving objects. Based on the real-time changes in the coverage areas of moving objects, it makes a preliminary prediction of the trajectory, speed and affected area of ​​the moving objects. It also performs strong dust suppression enhancement on the terminals of the environmental dust suppression module 3 within a threshold range set with the moving objects as the origin, and weak dust suppression enhancement on the terminals of the environmental dust suppression module 3 within a threshold range set with the moving objects as the origin and the moving objects as the direction of movement.

[0039] The enhanced dust suppression effect of the strong dust suppression is greater than the dust suppression effect of the current corresponding mobile dust source dust suppression module 1 terminal, which is greater than the enhanced dust suppression effect of the weak dust suppression.

[0040] The dust suppression methods of the dust suppression terminals of the mobile dust source dust suppression module 1, the fixed dust area dust suppression module 2, and the environmental dust suppression module 3 are water spraying or water spraying and dust suction.

[0041] The range of strong dustfall enhancement is determined by the movement path of the moving object, while the range of weak dustfall enhancement is determined by the tangential direction of the current movement of the moving object. The axial length of the strong dustfall enhancement range is greater than the axial length of the weak dustfall enhancement range.

[0042] The dust reduction control module 44 forces each terminal of the environmental dust reduction module 3 to perform dust reduction behavior equivalent to the dust reduction information and dust reduction degree after receiving the time data feedback from the timer module 41, based on the information received from the mobile dust source dust reduction module 1.

[0043] The dust reduction control module 44 performs dust reduction control on each terminal of the dust source module 42 in the production process based on the production attribute information of the received dust reduction enhancement position signal. The dust reduction level of the dust reduction control is a variable determined based on the production attribute information.

[0044] When the dust suppression terminal of the mobile dust source dust suppression module 1 enters the coverage area of ​​the dust suppression terminal of the fixed dust area dust suppression module 2, the dust suppression terminal of the mobile dust source dust suppression module 1 suspends the signal connection with each dust suppression terminal of the environmental dust suppression module 3.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
