Description

Technical Field

[0001] This utility model relates to the field of mine safety and information monitoring technology, specifically a portable monitoring device for recording underground mine filling data. Background Technology

[0002] Backfilling of goaf areas in underground mines is a crucial step in mine safety and resource recovery, primarily used to maintain roof stability, prevent ground pressure disasters, and control surface subsidence. Currently, most backfilling operations rely on manual execution of each step according to Standard Operating Procedures (SOPs), with time and step management managed manually. However, in practice, due to complex environments, busy personnel, or limited recording methods, inaccurate or missing operation time records are common, leading to deviations in the calculation of solidification time at each stage of the backfilling process, thus affecting the backfilling effect. Furthermore, failure to complete some steps in a timely manner may delay the formation of backfill strength, increasing the potential risk to goaf stability. Existing backfilling processes generally lack real-time monitoring and data archiving methods for backfill strength, making it impossible to promptly grasp the backfilling effect and hindering subsequent data accumulation and theoretical research. While some mines have attempted to supplement this with sensors or manual inspections, the overall monitoring remains fragmented and independent, lacking systematic and portable recording and monitoring equipment. Therefore, there is an urgent need for a portable device that integrates process recording, strength monitoring, and data archiving functions to improve the standardization and reliability of underground mine backfilling operations.

[0003] To address the aforementioned issues, several technologies have been publicly disclosed: CN113607465A "Portable Uniaxial Test," which uses on-site core sampling for strength analysis of filling materials. The entire system can be manually carried into the well to monitor the filling material, enabling portable / in-situ recording of strength data; ZL201921908037.9 "Portable In-situ Performance Monitoring Simulation Device for Filling Material," which allows for filling material monitoring, portable / in-situ parameter acquisition; ZL202010552475.7 "Environmentally Friendly Precision Measurement Device for Mine Filling Concentration," which enables online / quasi-online measurement and data acquisition of filling concentration; and CN203148370U "Mine Filling Material Stress and Deformation Monitoring System," which enables online monitoring of the filling material's stress / deformation. CN202467929U "Online Monitoring System for Filling Material Performance" enables online monitoring of filling materials and data uplink / master server; CN221074362U "Device for Venting and Steady-State Conveying of Slurry in Filling Pipelines" is an venting box + pressure control unit that improves steady-state conveying and reduces the risk of blockage and explosion; it facilitates the overlay of pressure / flow rate data. Related: Pipeline / Slurry, Pressure / Steady-state, Online Monitoring Interface; CN111853553A "Method and System for Fluid Pipeline Fault Detection" can detect pipeline faults, friction resistance / flowability coefficients, and anomalies.

[0004] These patented technologies still have shortcomings such as incomplete records of underground mine backfilling operations, insufficient intensity monitoring, and a lack of systematic data archiving.

[0005] Therefore, it is of great significance to develop a portable recording and monitoring device for underground mine filling data. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a portable recording and monitoring device for underground mine filling data. Through the synergistic effect of process completion recording, image acquisition, real-time intensity monitoring, and electronic report output, it effectively improves the standardization and reliability of the filling construction process and reduces safety hazards caused by human error or missing information.

[0007] The innovative features of this utility model are:

[0008] (1) Process recording and image linkage: Through the synchronous triggering of the process completion button and the camera, the construction time and image information are recorded simultaneously, avoiding human omissions.

[0009] (2) Real-time strength monitoring: Set up a strength sensor interface and display screen to display the strength data of the filling material in real time and dynamically monitor the solidification process.

[0010] (3) Data integration and electronic report output: Automatically integrate process records, image data and intensity data, generate electronic reports with one click, and support wired or wireless transmission to the ground system.

[0011] (4) Portable and stable design: The device adopts a telescopic support frame, support chassis and telescopic power cord to ensure the stability and continuous operation of the device in complex downhole environments.

[0012] To accomplish the above tasks, this utility model adopts the following technical solution:

[0013] The portable recording and monitoring device for underground mine backfilling data comprises, from top to bottom, a rotating handle and recording camera for recording the completion time of each process and archiving video information, a process recording display screen with a strength monitoring display screen on the side, a retractable support frame, and a retractable support chassis. One side of the strength monitoring display screen is connected to a data interface for backfilling strength monitoring. At the bottom of the process recording display screen, from left to right, are buttons linked to the backfilling strength monitoring data interface: a retaining wall completion record button, a retaining wall shotcrete completion record button, a first-stage bottom backfilling completion record button, a second-stage backfilling completion record button, and an electronic report sending button, used to record the completion time of each process and archive video information. The process recording display screen is equipped with a retractable charging power cord. The strength monitoring display screen has a data interface for connecting a strength sensor and displaying data in real time on the monitoring screen. The electronic report sending button integrates the construction process records and monitoring data into a complete electronic report and outputs it to the surface system.

[0014] Compared with the prior art, this utility model has the following advantages or effects:

[0015] Because the filling process is synchronized with the camera by linking the completion button, the error of manual recording can be effectively reduced. At the same time, due to the setting of a strength sensor interface and display screen, the process records, video data and strength data can be automatically integrated, generating an electronic report with one click and supporting wired or wireless transmission to the ground system to display the strength data of the filling material in real time and dynamically monitor the solidification process. In addition, due to the use of a telescopic support frame, support chassis and telescopic power cord, the stability and continuous operation of the device can be guaranteed in complex downhole environments.
