In terms of drilling power, ordinary motors struggle to precisely control speed and position, and torque cannot be flexibly adjusted in complex geological conditions, leading to unstable drill bit operation, inaccurate data, and impacting monitoring. Data acquisition methods are outdated; manual measurements are prone to errors, and simple sensors lack accuracy and real-time performance, resulting in unreliable data for fracture height determination. Furthermore, the devices have low levels of intelligence, lacking intelligent control and depth analysis components.

[0035] Working principle and process of a coal mine water-conducting fracture zone height observation device: This observation device relies primarily on the coordinated operation of its various components to monitor the height of water-conducting fracture zones in coal mines. Each component plays a distinct role: Power Drive: The servo motor 4 serves as the power source for the entire device, enabling precise speed and position control to drive the drill bit 9 to drill stably and efficiently. Under complex and variable underground geological conditions, the servo motor 4 can also flexibly adjust its torque to ensure continuous and stable observation operations. Data Acquisition: The distance sensor 15 captures the drilling depth and position information of the drill bit 9 in real time and with high precision, providing crucial data for accurately determining the height of the water-conducting fracture zone. Data Analysis and Control: The host unit 5 intelligently regulates the servo motor 4, receives and deeply analyzes the data transmitted from the distance sensor 15, and quickly generates intuitive and accurate observation results. Structural Protection and Adaptability: The reinforcement layer 16 enhances the strength of the drill bit 9, enabling it to withstand greater pressure and friction when dealing with complex geological conditions such as hard rock formations, preventing damage to the drill bit 9; the protective layer 17 isolates the drill bit 9 from corrosive substances downhole, preventing chemical erosion and physical wear, and extending its service life; the telescopic hollow tube 10 provides overall protection, reducing damage caused by external collisions and compression, and can flexibly extend and retract according to the drilling depth, improving the device's adaptability to different working conditions. Device Installation: Fix the observation device in a suitable position using the fixing plate 3, ensuring that the observation device body 1 at the lower end of the fixing body 2 is in a stable state to ensure the accuracy of subsequent observations. Connection Cable 7: Fix the interface 11 of the connection cable 7 on the left side of the host 5 to the middle right side of the servo motor 4, ensuring that the host 5 can control the servo motor 4 and transmit data. At the same time, check whether the connections between the components are secure. Parameter Setting: Set the initial parameters (such as speed, torque, etc.) of the servo motor 4 through the touch screen 6 at the front of the host 5 to prepare for drilling operations. Servo motor 4 is started: The host 5 sends a start signal to the servo motor 4, which starts working, driving the shaft 12 to rotate, and then driving the telescopic column 13 and drill bit 9 to start drilling. Drilling parameters are adjusted: During drilling, the servo motor 4 flexibly adjusts its torque according to preset parameters and actual geological conditions to adapt to different geological conditions and ensure stable drilling operations. Real-time monitoring of drilling depth and position: The distance sensor 15 in the groove 14 at the lower end of the telescopic column 13 collects the drilling depth and position information of the drill bit 9 in real time and transmits this data to the host 5. Protective measures are implemented: The reinforcement layer 16 enhances the strength of the drill bit 9, enabling it to withstand the pressure and friction during drilling; the protective layer 17 isolates the drill bit 9 from corrosive substances downhole, protecting it from corrosion; the telescopic hollow tube 10 flexibly extends and retracts according to the drilling depth, providing protection for the device and reducing damage caused by external collisions and compression. Data reception and processing: The host 5 receives the data from the distance sensor 15 and performs in-depth analysis on this data. By analyzing the drilling depth and position information, the height of the water-conducting fracture zone is determined.Observation Results Generation: Based on data analysis, the main unit 5 quickly generates intuitive and accurate observation results, which are displayed on the touchscreen 6 for easy viewing by operators. Drilling Stop: When the preset drilling depth is reached or the observation task is completed, the main unit 5 sends a stop signal to the servo motor 4, causing the servo motor 4 to stop working and the drill bit 9 to stop drilling. Device Retrieval: The observation device is removed from its installation location and properly stored for future use. Through the above working principles and processes, this coal mine water-conducting fracture zone height observation device can efficiently and accurately complete observation tasks, providing strong technical support for coal mining.
