It addresses the problems of high backfilling costs and difficulty in determining the amount of backfill used. This high-efficiency, low-cost downward-entry cemented backfilling mining method includes segmented along-vein transport roadways, mining area ramps, ore passes, return air connecting roadways, and return air level roadways in the preparatory engineering. Backfilling is performed in two or more stages, with high-strength backfilling within a certain height range at the bottom of the roadway, serving as the roof for the second-stage, first-step mining approach.

Description

Technical Field

[0001] This invention relates to the field of down-path cemented backfilling technology, specifically to a high-efficiency, low-cost down-path cemented backfilling mining apparatus and implementation method. Background Technology

[0002] Downward-entry layered backfill mining requires the backfill body to have high strength to form a stable artificial false roof, ensuring the safety of workers and equipment. Generally, no further support is required during the downhole mining process.

[0003] Chinese patent CN112196538B discloses a method for mining with a combined inclined incline and downward approach cemented backfilling. This method primarily involves stope design, arranging the stope along the ore body strike, determining the approach width based on the ore body thickness, and determining the approach height based on the degree of ore body fragmentation; pre-cutting engineering; roof control, with anchor mesh support after constructing the inclined incline, along-vein drilling roadways, and approach; steel arch support in severely fragmented areas, particularly at the large exposed areas of the inclined incline and approach openings, where dense steel arch support is used; ore extraction, using a combination of muck loader, electric tricycle, and electric scraper after blasting and ventilation; mechanical layer transfer; and cemented backfilling. While this patent solves the mining problems, the following issues remain in practical operation:

[0004] 1. Mining and backfilling are costly and inefficient, making it impossible to maximize the recovery of ore resources under complex geological conditions and to fully protect the safety of the mining face.

[0005] 2. When multiple filling material usage data are transmitted, the large amount of data transmitted can cause channel congestion and affect data transmission efficiency.

[0006] 3. When filling the downward path, the amount of filling material used in the process was not statistically analyzed, making it impossible to conduct anomaly analysis on the amount of filling material used and to effectively identify abnormal sections. Summary of the Invention

[0007] The object of the present invention is to provide a high - efficiency and low - cost downward drift cemented filling mining device and implementation method. The drift filling is carried out in two or more times to fill to the roof, and high - strength filling is carried out within a certain height range at the bottom of the drift. As the roof of the stope for the first - step mining of the second slice, a low - strength filling body is used to connect the top above the high - strength filling body. After all the ore bodies in the first slice are mined and filled, a second - slice connecting roadway and slice roadway are dug from the sectional cross - vein haulage roadway to the central part of the panel stope until the hanging wall or footwall of the ore body, and then the ore body is mined and filled, and so on until the ore body mining is completed. Compared with the conventional downward drift cemented filling, the mining efficiency is improved and the filling cost is reduced, and the problems in the prior art can be solved.

If so, take the first abnormal value and the time interval as the first abnormal data; otherwise, determine that the first abnormal value is invalid.

[0043] The data integration unit is used to periodically label the first abnormal data to obtain the first valid abnormal data, to non-periodically label the second abnormal data to obtain the second valid abnormal data, to use the first and second valid abnormal data as the final valid abnormal data, and to store the final valid abnormal data separately.

The numerical sequence is then divided using these multiple split points to obtain multiple different second subsequences. From the second subsequences, a third subsequence with a value greater than a preset value is obtained. Based on the position of the third subsequence in the numerical sequence, the abnormal time interval of the third subsequence is determined. A fourth subsequence is then obtained from the adjacent third subsequences whose abnormal time intervals are within the preset time interval range. The fourth subsequence and the abnormal time interval are used as second abnormal data.

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0047] 1. An efficient and low-cost downward drift cemented filling mining device and implementation method provided by the present invention. Stratified crossheading and stratified roadways are excavated from the sectional crosscut haulage roadway towards the central part of the panel stope until the upper or lower wall of the ore body. Then, stoping is carried out in the form of horizontal drifts along the strike of the ore body, and multiple drifts in each panel are stoped simultaneously. The upper and lower stratified drifts are arranged in a staggered "pin" shape. When stoping the lower stratified drift, the ore body or filling body on both sides of the stoping drift is used to support the upper stratified drift to prevent the upper stratified filling body from moving down or caving in. The same stratified drift is stoped in three steps. That is, in the first step of stoping, "mining one out of every four" is carried out to form the first-step stoping drift of the first stratification. After the first-step stoping and filling are completed, "mining one out of every two" is carried out in the second step to form the second-step stoping drift of the first stratification. Finally, the third-step stoping drift of the first stratification is carried out. The drift filling is carried out in two or more times to fill to the top. High-strength filling is carried out within a certain height range at the bottom of the drift to serve as the roof for the stoping of the first-step stoping drift of the second stratification. A low-strength filling body is used to top the high-strength filling body. After all the ore bodies in the first stratification are stoped and filled, the second-stratified crossheading and stratified roadways are excavated from the sectional crosscut haulage roadway towards the central part of the panel stope until the upper or lower wall of the ore body, and then ore body stoping and filling are carried out, and so on until the ore body stoping is completed. Compared with the conventional downward drift cemented filling, the mining efficiency is improved and the filling cost is reduced.

[0048] 2. An efficient and low-cost downward drift cemented filling mining device and implementation method provided by the present invention. By setting the number of dataset transmissions according to the actual situation of the communication channels for transmitting the usage data of filling materials in multiple regions, the matching degree between the number of dataset transmissions and the actual situation of the channels can be effectively improved, thereby effectively improving the data transmission efficiency and data transmission stability, and preventing the problem that the one-time random transmission method of the dataset cannot be set针对性 according to parameters such as the actual saturation of the channel, resulting in too large single data transmission volume causing channel blockage and affecting data transmission efficiency, and too small single data transmission volume causing waste of channel resources.

[0049] 3. An efficient and low-cost downward drift cemented filling mining device and implementation method provided by the present invention. While ensuring that the numerical value meets the abnormal requirements, the time interval is also judged. Exceeding the preset time interval indicates that the time between two first abnormal numerical values is relatively long and cannot be used as valid abnormal data. The first abnormal numerical value and the time interval are used as the first abnormal data, reducing the redundancy of abnormal data and ensuring the accuracy of the obtained first abnormal data. The first valid abnormal data and the second valid abnormal data are used as the final valid abnormal data, ensuring the clarity, definiteness and accuracy of the finally obtained valid abnormal data, thereby providing a basis for judging and making decisions on the numerical value of the filling material usage data, facilitating the self-judgment of the filling material usage data, and judging whether there is an abnormality in a certain section of the filling material.

Detailed Implementation

[0063] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0064] To solve the problems in the prior art, such as high mining filling cost, low efficiency, inability to recover ore resources to the maximum extent under complex geological conditions, and inability to fully protect the safety of the stope working face, please refer to Figures 1-8 This embodiment provides the following technical solutions:

[0065] An efficient and low-cost downward drift cemented filling mining device includes a sectional drift transportation roadway 1 for development and preparation engineering, a mining area ramp 3, a ore pass 4, a return air connection roadway 9, and a return air level roadway 10. From the sectional drift transportation roadway 1, a stratified connection roadway 2 and a stratified roadway 5 are excavated towards the central part of the panel stope until the hanging wall or footwall of the ore body, and then stoping is carried out in the form of horizontal drifts along the strike of the ore body. Multiple drifts in each panel are stoped simultaneously. Among them, the cutting engineering includes a stratified connection roadway 2, a stratified roadway 5, a filling return air raise 6, a personnel ventilation shaft 7, and a filling roadway 12; only the stratified roadway 5 in the cutting engineering is arranged within the vein, and other engineering is arranged outside the vein. Each sectional roadway is connected through the mining area ramp 3. A stratified connection roadway 2 is excavated from the sectional drift transportation roadway 1 to the ore body. The upper part of the high-strength filling body 17 is topped with a low-strength filling body 16, and the working process is carried out on the filling main body 23.

[0066] An implementation method for efficient and low-cost downward drift cemented filling mining includes the following steps:

[0067] S1: The upper and lower stratified drifts are arranged in a "pin" shape. The same stratified drift is stoped in three steps. That is, in the first step of stoping, "one is mined every three is left", after the first step of stoping and filling is completed, the second step of "one is mined every one is left" is carried out, and finally the third step of stoping is carried out, and the stoping data of each step is collected;

[0068] S2: The same stratified drift can also be stoped in multiple steps. There are multiple drifts between the two stoping drifts. The stratified drift is stoped and filled in several steps, and the stoping and filling data of several steps are collected;

[0069] S3: The drift filling is carried out in two or more times for topping. High-strength filling is carried out within a certain height range at the bottom of the drift as the roof for the stoping of the next stratified drift. The upper part of the high-strength filling body 17 is topped with a low-strength filling body 16, and the working process is carried out on the filling main body 23, and the filling data is collected;

[0070] S4: Transmit the data collected at each stage in a unified manner, effectively match the actual situation between the data according to the data of each type, and make targeted settings for the data transmission channel;

[0071] S5: Perform data analysis on the data transmitted at each stage and make numerical judgments on the data for each filling cycle.

[0072] The mining steps in S1 include: mining the same stratified route in three steps, namely, the first step of mining involves "mining every three steps to form the first-step mining route 15 for the first stratum; after the first step of mining and filling is completed, the second step involves "mining every one step to form the second-step mining route 18 for the first stratum"; finally, the third-step mining route 20 for the first stratum is performed. The production panel is divided along the strike of the ore body, with a panel length of 60m-80m and a panel width equal to the horizontal thickness of the ore body. The access route is 3.5m × 3.5m in size. The filling steps in S3 include: filling the access route in two or more stages to reach the top; high-strength filling is performed within a certain height range at the bottom of the access route to form a high-strength filling body 17. As the second-level first-step mining approach 22 for mining the roof, the high-strength backfill 17 is topped with a low-strength backfill 16. The high-strength backfill 17 part of the approach uses a lime-sand ratio of 1:4-1:6, a compressive strength greater than 3MPa, and a filling height of 1.5m. The backfill with the roof has a lime-sand ratio of 1:8, a compressive strength greater than 1MPa, and a backfill height of 2.0m. The mining steps for S1 also include: after the first-level ore body is completely mined and backfilled, the second-level connecting roadway 2 and the level roadway 5 are excavated from the segmental vein transport roadway 1 to the center of the panel mining area until the upper or lower plate of the ore body, and then the ore body is mined and backfilled, and so on, until the ore body mining is completed.

[0073] Specifically, for panel mining of ore body division, according to the ore body shape, the stoping drifts can be arranged along the strike direction of the ore body or perpendicular to the strike of the ore body. The development workings include the sublevel drift along the vein 1, the ramp in the mining area 3, the ore pass 4, the return airway crossheading 9, and the return airway level 10; the cutting workings include the crossheading between slices 2, the slice roadway 5, the filling return air raise 6, the manway and ventilation raise 7, and the filling roadway 12. Only the slice roadway 5 in the cutting and development workings is arranged within the vein, and other workings are arranged outside the vein. Each sublevel roadway is connected through the ramp in the mining area 3, and the crossheading between slices 2 is driven from the sublevel drift along the vein 1 towards the ore body. The sequence of development and cutting is: ramp in the mining area 3 → sublevel drift along the vein 1 → crossheading between slices 2 → slice roadway 5 → stoping drift. Among them, the stoping process of the downward drift cemented filling method includes: rock drilling, charging, blasting, ventilation, scaling, ore drawing, and support. The crossheading between slices 2 and the slice roadway 5 are driven from the sublevel drift along the vein 1 towards the central part of the panel stope until the hanging wall or footwall of the ore body, and then stoping is carried out in the form of horizontal drifts along the strike of the ore body. Multiple drifts in each panel are stoped simultaneously. The upper and lower slices of drifts are arranged in a staggered "pin" shape. When stoping the lower slice of drifts, the ore body or filling body on both sides of the stoping drift is used to support the upper slice of drifts to prevent the filling body in the upper slice from moving down or caving. The stoping of the same slice of drifts is carried out in three steps. That is, in the first step of stoping, "mining one out of every four" is carried out first to form the first-step stoping drift 15 of the first slice. After the first-step stoping and filling are completed, the second step of "mining one out of every two" is carried out to form the second-step stoping drift 18 of the first slice. Finally, the third-step stoping drift 20 of the first slice is carried out. The filling of the drift is carried out in two or more times to fill to the top. High-strength filling 17 is carried out within a certain height range at the bottom of the drift to serve as the roof for the stoping of the second-step stoping drift 22 of the second slice. The upper part of the high-strength filling body is topped with a low-strength filling body 16. After all the ore bodies in the first slice are stoped and filled, the crossheading between slices 2 and the slice roadway 5 of the second slice are then driven from the sublevel drift along the vein 1 towards the central part of the panel stope until the hanging wall or footwall of the ore body, and then the ore body is stoped and filled, and so on until the stoping of the ore body is completed. Compared with the conventional downward drift cemented filling, the mining efficiency is improved and the filling cost is reduced.

[0074] To solve the problem that in the prior art, when multiple filling material consumption data are transmitted, due to the excessive quantity transmission flow rate, the channel is blocked, affecting the data transmission efficiency, please refer to Figure 9 and Figure 10 , the following technical solutions are provided in this embodiment:

[0075] The data transmission for each stage of S4 includes: a data acquisition module for acquiring statistical data on the quantity of materials used in each process within a preset unit time period in each step stage; a channel acquisition module for acquiring the communication channel between the current material usage data of each process and the unified data receiving platform, and assigning a unique encoding label to each communication channel; a channel parameter acquisition module for scanning each communication channel sequentially according to the unique encoding label to acquire the channel parameters of each communication channel; wherein, the channel parameters include the communication channel saturation and the current remaining capacity of the communication channel; a retrieval module for retrieving the data transmission setting parameter model; a transmission count setting module for determining the number of datasets transmitted in a single transmission for each channel in a single data transmission based on the data transmission setting parameter model and using the communication signal saturation and the current remaining capacity of the communication channel; and a data transmission module for transmitting data sequentially through the communication channels according to the number of datasets transmitted in a single transmission after determining the number of datasets transmitted in a single transmission for each channel in a single data transmission.

[0076] The data transmission module includes: a data packet forming module, used to divide and package several sub-data sets according to the number of data packets transmitted in a single transmission, to obtain multiple standard data packets and one reserve data packet; a data transmission execution module, used to transmit the multiple standard data packets sequentially through each communication channel to a unified data receiving platform; a transmission speed acquisition module, used to acquire the data transmission speed of each communication channel for the standard data packets during the data transmission process, and acquire the three communication channels with the fastest data transmission speed; a target channel acquisition module, used to acquire the remaining communication capacity of the three communication channels with the fastest current communication channel speed, and extract the communication channel with the largest remaining communication capacity as the target channel; a binding module, used to bind the reserve data packet with any one of the standard data packets to be transmitted, forming a mixed data packet to be transmitted; and a binding transmission module, used to send the mixed data packet to be transmitted to the target channel for data transmission after the current data transmission on the target channel is completed.

[0077] Specifically, setting the number of data sets transmitted based on the actual communication channel conditions for data transmission of filling material usage in multiple regions can effectively improve the matching degree between the number of data sets transmitted and the actual channel conditions, thereby effectively improving data transmission efficiency and stability. This prevents the problem of data sets being transmitted randomly at once, which cannot be specifically set according to parameters such as the actual channel saturation, resulting in excessive data transmission volume in a single transmission causing channel congestion and affecting data transmission efficiency, as well as the problem of excessive data transmission volume in a single transmission causing waste of channel resources.

[0078] To address the issue in existing technologies where the amount of filling material used in the downward feed is not statistically analyzed, thus hindering anomaly analysis and effective identification of abnormal areas, please refer to [link to relevant documentation]. Figure 11 and Figure 12 This embodiment provides the following technical solution:

[0079] The analysis of data for each filling cycle in S5 includes: a data comparison module, used to acquire process material usage data from multiple communication channels and compare the received data with the stored normal threshold data; a comparison data calculation module, used to calculate the numerical difference between the process material usage data and the data information of the qualified range value; and a calculation data reading module, used to read the result of the difference calculation and perform a qualified detection on the read value. The calculation data reading module includes: a sequence judgment unit, used to acquire the numerical sequence of the data difference calculation, perform periodic detection on the numerical sequence, and determine whether the numerical sequence is a periodic sequence; and a sequence analysis unit, used to, when the numerical sequence is determined to be a periodic sequence, divide the numerical sequence according to the period to obtain multiple identical first subsequences, determine whether all values ​​in the first subsequence are greater than a preset value, and if so, extract the first abnormal value in the first subsequence that is greater than the preset value, determine the time interval between adjacent first abnormal values, and determine whether the time interval is within the preset time interval range. If so, the first abnormal value and time interval are taken as the first abnormal data; otherwise, the first abnormal value is determined to be invalid. The data integration unit is used to periodically label the first abnormal data to obtain the first valid abnormal data, to non-periodically label the second abnormal data to obtain the second valid abnormal data, to take the first valid abnormal data and the second valid abnormal data as the final valid abnormal data, and to store the final valid abnormal data separately. The sequence analysis unit is also used to: when the numerical sequence is determined to be a non-periodic sequence, to perform clustering operation on the numerical sequence using a one-dimensional clustering method to obtain multiple split points, and to divide the numerical sequence using multiple split points to obtain multiple different second subsequences, to obtain a third subsequence from the second subsequences that has a value greater than a preset value, and to determine the abnormal time interval of the third subsequence based on the position of the third subsequence in the numerical sequence, and to obtain a fourth subsequence from the adjacent third subsequence whose abnormal time interval is within the preset time interval range, and to take the fourth subsequence and the abnormal time interval as the second abnormal data.

[0080] Specifically, the numerical sequence of filling materials is first periodically analyzed. Different methods are used to analyze periodic and non-periodic sequences to ensure the focus and efficiency of sequence analysis. Specifically, the periodic sequence is divided into identical first subsequences. The values ​​of the first subsequences and the time intervals between the first outlier values ​​are evaluated. While ensuring the values ​​meet the anomaly requirements, the time intervals are also evaluated. Exceeding a preset time interval indicates a long interval between two first outlier values, which cannot be considered valid anomaly data. The first outlier value and the time interval are used as the first anomaly data, reducing redundancy and ensuring the accuracy of the obtained first anomaly data. However, a different sequence analysis method is used for non-periodic sequences. Specifically, a one-dimensional clustering method is first used to cluster the numerical sequence, obtaining multiple segmentation points. This makes the segmentation more accurate and objective, providing a basis for subsequent anomaly analysis. After dividing the aperiodic sequence, a third subsequence greater than a preset value is extracted. Based on the position of the third subsequence in the aperiodic sequence, the abnormal time interval of the third subsequence is determined. Similarly, the abnormal time intervals are judged, and the third subsequences that are not within the preset time interval range are removed to obtain a fourth subsequence. Finally, the fourth subsequence and the abnormal time intervals are used as the second abnormal data to ensure the accuracy of the obtained second abnormal data. Finally, the first abnormal data is periodically labeled to obtain the first valid abnormal data, and the second abnormal data is aperiodically labeled to obtain the second valid abnormal data. The first and second valid abnormal data are used as the final valid abnormal data to ensure the clarity and accuracy of the final valid abnormal data. This provides a basis for judging and making decisions on the numerical values ​​of filling material usage data, and facilitates the self-judgment of filling material usage data to determine whether a certain segment of filling material is abnormal.
