Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to a system and method for measuring the amount of ore in a chute in an underground mining area of ​​a mine. Background Art

[0002] The chute in the underground mining area is the throat of the mine for transporting ore. The weakness of chute ore discharge is that once the chute fails, it will affect the stage transportation capacity and the lifting capacity of the shaft, and then affect the production of the entire mine. The failure of the chute is mainly due to the wear and blockage of the chute. These two major problems are not only unsafe to deal with, but also have a long treatment cycle and high cost, which seriously affects the production of the mine. Relatively speaking, the blockage of the chute is more frequent than the wear and damage of the chute, especially when the production and management are chaotic.

[0003] The main reason for ore blockage in the chute is that the ore has been stored for too long, which is easy to form agglomerations, causing the ore to form an arch when it is released later. Therefore, timely chute ore transportation is very necessary. The wear of the chute is mainly the impact of the upper ore falling on the chute. It is also very necessary to reduce the drop of iron ore in the chute and reduce the impact and wear of iron ore on the chute wall. Therefore, how to adjust the transportation volume of iron ore in the upper and lower stages requires real-time control of the ore inventory in the chute.

[0004] Under this requirement, accurate real-time automatic measurement of chute ore volume can not only minimize chute blockage and wear, but also improve enterprise management level, grasp the underground mine production situation in real time, save energy and increase efficiency of the underground transportation system, and make the entire underground production operation scheduling more flexible and accurate.

[0005] However, the existing monitoring technology is greatly affected by the dust in the chute, or by the dust and flatness of the ore falling in the chute, the measurement is inaccurate, the false alarm rate is high, and the installation of the equipment is limited by the chute dropping process (affected by the ore screen at the top of the chute), the installation or maintenance is inconvenient, and it is easy to be damaged by the ore. Summary of the invention

[0006] The present invention provides a mine chute ore quantity metering system and method in an underground mining area, so as to solve the technical problems existing in the prior art such as being greatly affected by chute dust, or being greatly affected by chute ore dust and pile flatness, inaccurate measurement, high false alarm rate, and the installation of the equipment is limited by the chute ore dropping process (affected by the ore placing grid screen at the top of the chute), inconvenient installation or maintenance, and easy to be damaged by ore.

The data provided by the system can help production management personnel flexibly and efficiently dispatch and command the underground electric locomotive 2 transportation operation, so as to achieve energy saving and efficiency improvement for the enterprise.

[0064] The electronic tag is a passive electronic tag, preferably an RFID tag. RFID (Radio Frequency Identification) technology, also known as wireless radio frequency identification, is a communication technology that can identify a specific target and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and the specific target.

[0065] The upper wireless substation 40 and the lower wireless substation 50 are RFID card readers. The upper wireless substation 40 is arranged on the top or side wall of the tunnel near the upper ore discharge place of the chute 3.

[0066] The lower wireless substation 50 is arranged on the top or side wall of the tunnel near the lower unloading place of the chute 3. Specifically, a vibrating ore discharger is arranged at the lower unloading place of the chute 3, and the lower wireless substation 50 is arranged on the top or side wall of the tunnel near the vibrating ore discharger.

[0067] The computer 20 is connected to the upper wireless substation 40 and the lower wireless substation 50 respectively through wireless communication or wired communication.

[0068] Preferably, the computer 20 is connected to the industrial Ethernet ring network 30 built underground in the mine through the wired network 24 (or wireless network) and then connected to the upper wireless substation 40 and the lower wireless substation 50 respectively.

[0070] The present invention provides a mine underground mining area chute 3 ore quantity measurement system, which is flexible in networking, easy to install, low in price, safe and reliable, and stable in operation, and effectively overcomes the defect that traditional measurement technology is easily affected by the process environment of the underground mining area. The data provided by the system can help production management personnel flexibly and efficiently dispatch and command underground electric locomotive 2 transportation operations, thereby achieving energy saving and efficiency improvement for the enterprise.

[0071] In addition, the present invention also discloses a method for measuring the amount of ore in a chute in an underground mining area of ​​a mine using the above-mentioned measuring system, which specifically includes:

[0072] Step 1: Install an electric locomotive electronic tag 51 on the electric locomotive 2 and install an electric forklift electronic tag 41 on the mining shovel 1;

[0073] An upper wireless substation 40 is arranged at the upper part of the chute 3, and a lower wireless substation 50 is arranged at the lower part of the chute 3;

[0074] Install shovel electronic tags on mining shovel loaders and install electric locomotive electronic tags on the head of underground transport electric locomotives. The electronic tags are passive tags that do not require power supply, and each tag has a unique ID. The wireless substation and the electronic tags use (RFID) wireless communication technology for data transmission.

[0075] Step 2: The upper wireless substation 40 reads the shovel information of the shovel electronic tag 41 through radio frequency identification (RFID) wireless communication to identify the shovel 1 used to place ore (dump ore) into the chute 3;

[0076] Step 3: The lower wireless substation 50 reads the electric locomotive information of the electric locomotive electronic tag 51 through radio frequency identification (RFID) wireless communication to identify the electric locomotive 2 used to transport the ore from the chute 3;

[0077] Step 4: The computer 20 is connected to the upper wireless substation 40 to record the shovel information and the number of times the shovel loader 1 releases the ore;

[0078] The computer 20 is connected to the lower wireless substation 50 to record the electric locomotive information and the number of transportation times of the electric locomotive 2;

[0079] The computer 20 summarizes the above information and calculates the ore quantity information of the chute 3.

[0080] In the application, there are multiple chutes 3, and the computer 20 monitors the ore volume of each chute 3 in real time to provide basic data for mine production scheduling and management.

[0081] Among them, the ore quantity information of chute 3 includes the total amount of incoming goods, the total amount of outgoing goods and the total amount of inventory.

[0082] The forklift information of the forklift electronic tag 41 includes at least the vehicle ID (vehicle number) of the forklift 1;

[0083] The forklift information of the forklift electronic tag 41 includes the transport weight (single load) of the forklift 1 to which it is attached; or the transport weight (single load) of each forklift 1 is stored in the database of the computer 20 .

[0084] The locomotive information of the locomotive electronic tag 51 at least includes the vehicle ID (vehicle number) of the locomotive 2; the locomotive information of the locomotive electronic tag 51 includes the transport weight (single load) of the locomotive 2 to which it is attached; or the transport weight (single load) of each locomotive 2 is stored in the database of the computer 20. The locomotive electronic tag 51 and the forklift electronic tag 41 store the chute 3 ID (chute 3 number information) information.

[0085] The information such as the affiliated unit, contact person or contact number of the electric locomotive 2 and / or the scraper 1 is stored in the electronic tag or in the database of the computer 20 .

[0086] The technical solution of the present invention solves the shortcomings of inaccurate and unstable instrument measurement due to the influence of production conditions and environment of ore discharge process of chute 3. The solution is technically mature, stable and reliable, low cost, not affected by the production process and environment of ore discharge of chute 3 underground, easy to manage, and real-time statistical measurement of ore volume of chute 3.

[0087] The system displays the ore inventory in chute 3 in real time, providing data basis for underground transportation scheduling, ensuring that underground locomotives do not run empty, reducing transportation energy consumption, and improving mine production management level and production efficiency.

[0088] By understanding the ore inventory and time in the chute 3, timely scheduling and management can effectively prevent the chute 3 from being blocked; by measuring the total amount of ore in the chute 3, a data basis is provided for analyzing and judging the wear condition of the chute 3, which are all related to the safe production of underground mining enterprises.

[0089] The process flow in actual application is as follows:

[0090] Shovel loader transports ore in the mining area → unloads in the chute in the mining area → the wireless substation above the chute mouth identifies the electronic tag information of the shovel → uploads data to the ground computer through the system network → the database collects data and analyzes and calculates → the upper computer program extracts data and displays the output of the existing ore volume in the chute; specifically, the ore volume in the chute increases by several cars of ore;

[0091] The electric locomotive transports ore → the ore is loaded into the chute in the mining area → the wireless substation at the bottom of the chute mouth identifies the electronic tag information of the electric locomotive → uploads data to the ground computer through the system network → the database collects data and analyzes and calculates → the upper computer program extracts data to display and output the current amount of ore in the chute; specifically, the amount of ore in the chute is reduced by several cars of ore.

[0092] The database of the computer or server can use the currently popular large-scale database Oracle11g, and the acquisition and analysis software is developed using powerbuilder9.0. The computer is interfaced with the RFID tag identification device (wireless substation). The wireless substation reads the number of ore unloading by the shovel loader in the morning and the number of transportation by the lower transport ore car in real time, and transmits it to the data center through the network. The data center acquisition and analysis software stores the data in the database in real time, and finally calculates the ore inventory in each chute through the software and displays it in a report.

[0093] The specific data collection and analysis process is as follows:

[0094] 1) The ID information of each electronic tag (scraper and transport locomotive) and the information of the upper wireless substation and the lower wireless substation (RFID reader) of each chute are established in the database through the database software, and each mine is numbered for identification and distinction;

[0095] That is, each mine is numbered to identify and distinguish each mine; a different shovel electronic tag is attached to each shovel loader to identify and distinguish different shovel loaders; a different electric locomotive electronic tag is attached to each electric locomotive to identify and distinguish different electric locomotives; different upper wireless substations and lower wireless substations are attached to the upper and lower parts of each chute to identify and distinguish different chutes.

[0096] 2) When the loader is unloading ore at the top of the mining chute, the upper wireless substation (RFID reader) of the chute reads the loader's shovel electronic tag and obtains the loader's ID, records the read loader ID and sends it to the ground data center (computer).

[0097] By matching and retrieving relevant information such as the shovel loader's transport weight and the basic information of the mine stored in the computer, the amount of ore transported by the shovel loader is obtained, and then the amount of ore transported by the shovel loader is uploaded to the computer database, and the existing amount of ore in the chute is calculated.

[0098] 3) When the transport locomotive arrives at the chute to load ore for transportation, the wireless substation (RFID reader) at the bottom of the chute reads the electronic tag of the transport locomotive and obtains the ID of the locomotive, records the read locomotive ID and sends the ID information to the ground data center (computer).

[0099] By matching and retrieving relevant information such as the locomotive transport weight and basic information of the mine stored in the computer, the amount of ore transported by the locomotive is obtained, and then the information on the amount of ore transported by the locomotive is uploaded to the computer database, and the existing amount of ore in the chute is calculated.

[0100] 4) Continuously update the information on the amount of ore in the chute, the amount of ore transported by the electric locomotive (ore transport information) and the amount of ore transported by the shovel loader (ore transport information) stored in the computer database. The real-time amount of ore in each chute can be calculated through collection and analysis software.

[0101] Among them, the database related table structure is designed as follows:

[0102]

[0103]

[0104]

[0105]

[0106] The specific algorithm process is as follows:

[0107] (Mine volume of the chute) = (Mine volume of each shovel of the scraper IDx) - (Mine volume of each train of the electric locomotive IDy);

[0108] like Figure 6 As shown, the ore reserves of each chute can be clearly displayed on the host computer or other computers.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
