Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shaft ground pressure monitoring, in particular to a ground pressure monitoring system for an under-construction super-deep shaft. BACKGROUND

[0002] With the gradual depletion of shallow mineral resources, mining deep mineral resources is the main development direction of future mining. The shaft is an important channel connecting the ground and underground space, and has important significance for mine construction and production. Compared with shallow shafts, deep shafts face complex engineering geological conditions such as high stress, water enrichment, and cyclic blasting disturbance during construction, which are prone to rock burst, water inrush, shaft deformation and other disasters, seriously affecting the safety of the project and the construction progress. Therefore, it is necessary to monitor the ground pressure of the shaft wall and surrounding rock to real-time perceive the stress, displacement, deformation and other information of the shaft surrounding rock, analyze and evaluate the health status of the shaft, so as to real-time early warning and timely take corresponding preventive measures to ensure the smooth construction and long-term stability of the shaft.

[0003] At present, the traditional shaft ground pressure monitoring methods include shaft deformation monitoring, structure state monitoring, and ground pressure dynamic monitoring. After years of development, certain technical progress has been made, but there are also some shortcomings.

[0031] Monitoring the ground pressure of the under-construction super-deep shaft is of great significance to ensure the smooth construction and long-term stability of the shaft 1. In order to solve the problem that the existing shaft ground pressure monitoring system lacks systematic cross-section monitoring and the data transmission is inconvenient, the present application provides a ground pressure monitoring system for under-construction super-deep shaft, which can synchronously monitor the whole section of each cross-section and ensure the stable transmission of monitoring data, realizing the comprehensive, real-time, long-term and stable monitoring of the ground pressure of the under-construction super-deep shaft.

[0032] Please refer to Figure 1 The embodiments of the present application provide a ground pressure monitoring system for under-construction super-deep shaft, comprising a sensor system arranged at a monitoring cross-section, an acquisition box 10 connected with the sensor system, and a ground receiving box 14 connected with the acquisition box 10 through a communication module; the sensor system comprises a first sensor system arranged at a shaft circular cross-section 2 and a second sensor system arranged at a horsehead door cross-section 3, and the first sensor system and the second sensor system each comprise a plurality of sensors connected with the acquisition box 10; in the shaft circular cross-section 2, monitoring points are symmetrically arranged along the direction parallel and / or perpendicular to the maximum horizontal principal stress; in the horsehead door cross-section 3, monitoring points are arranged on the sidewall of the shaft 1 and the side slope of the horsehead door.

[0033] The shaft 1 of the under-construction super-deep shaft is provided with a horsehead gate at intervals in the vertical direction, so that the under-construction super-deep shaft has two different cross sections, one being the ordinary cross section of the shaft, i.e. the shaft circular cross section 2, and the other being the horsehead gate cross section 3. The embodiments of the present application alternately divide the shaft circular cross section 2 and the horsehead gate cross section 3 in the vertical direction of the shaft 1, and set monitoring points at specific positions in the ordinary cross section of the shaft (i.e. the shaft circular cross section 2) and the horsehead gate cross section 3, and set sensors in the corresponding monitoring points, so that the monitoring data in the super-deep shaft can be more comprehensively and effectively collected, so as to accurately evaluate the health status of the shaft 1 based on the monitoring data. Meanwhile, the sensors of different cross sections are connected to the collection box 10, and the collection box 10 is connected to the ground receiving box 14 set on the ground through the communication module, so that the monitoring data of each cross section can be synchronously transmitted while improving the stability of data transmission, realizing the synchronous and simultaneous monitoring of the ground pressure of the super-deep shaft in multiple cross sections, and further realizing the full coverage of the full-depth ground pressure monitoring area of the shaft 1.

[0034] Further, please refer to Figure 2 In some embodiments of the present application, four monitoring points are provided in the shaft circular cross section 2, including two monitoring points symmetrically arranged along the direction parallel to the maximum horizontal principal stress and two monitoring points symmetrically arranged along the direction perpendicular to the maximum horizontal principal stress. For example, when the direction of the maximum horizontal principal stress is NW (300°), the 300° direction of the shaft wall consistent with the direction can be set as the No. 1 point, the 30° direction of the shaft wall can be set as the No. 2 point, the 120° direction of the shaft wall can be set as the No. 3 point, and the 210° direction of the shaft wall can be set as the No. 4 point. The No. 1 point and the No. 3 point are symmetrically arranged along the direction parallel to the maximum horizontal principal stress, and the No. 2 point and the No. 4 point are symmetrically arranged along the direction perpendicular to the maximum horizontal principal stress.

[0035] More specifically, the first sensor system includes a first sensor assembly provided at each monitoring point of the shaft circular cross section 2; the first sensor assembly includes a displacement meter 4, a stress meter 5, a soil pressure cell 6, and a set of strain gauges 7 (including three strain gauges 7, and the corresponding test directions are X, Y, and Z directions). In this way, the collected monitoring data can more accurately reflect the ground pressure change in the shaft circular cross section 2.

[0036] The displacement meter 4 and the stress meter 5 are installed inside the surrounding rock at the corresponding monitoring point through a borehole, and the borehole is tightly combined with the surrounding rock by grouting to seal the borehole; the soil pressure cell 6 is attached to the rock wall at the corresponding monitoring point by coupling agent, and can be further fixed by steel wire to prevent it from falling off; and the strain gauges 7 are installed in the concrete lining at the corresponding monitoring point through a support.

[0037] In other embodiments of the present application, the specific type, number and installation method of the sensors in the first sensor assembly can be reasonably adjusted according to actual conditions. For example, 1-2 pore water pressure gauges can be selected according to the water content of the surrounding rock of the well wall.

[0038] Further, the cables of the sensors in the first sensor system are all threaded into the threading hose 8 after being combed, and the cables of the sensors arranged at the same monitoring point are threaded into the same threading hose 8. The threading hoses 8 corresponding to the monitoring points in the wellbore circular section 2 are annularly laid along the well wall and are fixed on the anchor net of the well wall by binding. All the threading hoses 8 corresponding to the monitoring points in the wellbore circular section 2 are led to the junction box 9 fixed on the well wall. The cables in the threading hoses 8 are integrated into one signal line through the junction box 9. The signal line output by the junction box 9 is vertically laid along the well wall and is led to the collection box 10 closest to it and is connected to the collection box 10. The threading hose 8 is a plastic hose with a steel wire lining inside. The cables of the sensors are threaded into the threading hose 8, which can well protect the cables and prolong their service life.

[0039] Further, please refer to Figure 3 In some embodiments of the present application, five monitoring points are arranged in the horsehead section 3, including two wellbore monitoring points and three horsehead monitoring points. The two wellbore monitoring points are arranged on the two sides of the wellbore 1, and the three horsehead monitoring points are arranged on the two sides of the main horsehead and on one side of the auxiliary horsehead. For example, when the horsehead direction is NE30°, the No. 1 point is arranged on the right side of the S horsehead, the No. 2 point is arranged on the W side of the well wall, the No. 3 point is arranged on the left side of the N horsehead, the No. 4 point is arranged on the right side of the N horsehead, and the No. 5 point is arranged on the E side of the well wall. The No. 2 point and the No. 5 point are the wellbore monitoring points arranged on the two sides of the wellbore 1, the No. 3 point and the No. 4 point are the horsehead monitoring points arranged on the two sides of the main horsehead, and the No. 1 point is the horsehead monitoring point arranged on one side of the auxiliary horsehead.

[0040] More specifically, the second sensor system includes a second sensor assembly arranged at each wellbore monitoring point and a third sensor assembly arranged at each horsehead monitoring point. The second sensor assembly includes one displacement meter 4, one stress meter 5, one soil pressure cell 6 and one set of strain gauges 7 (including three strain gauges 7, and the corresponding test directions are X, Y and Z directions). The third sensor assembly includes one displacement meter 4 and one soil pressure cell 6. In this way, the collected monitoring data can more accurately reflect the ground pressure changes in the wellbore circular section 2.

[0041] The installation mode of the displacement meter 4, the stress meter 5, the earth pressure cell 6 and the strain meter 7 is consistent with the installation mode of the corresponding sensors in the wellbore circular section 2, and will not be described here. In other embodiments of the present application, the specific types, numbers and installation modes of the sensors in the second sensor assembly and the third sensor assembly can be reasonably adjusted according to actual conditions.

[0042] Further, the cables of the sensors in the second sensor system can be threaded into the threading hose 8 in a similar manner as in the first sensor system, and the cables of the sensors arranged at the same monitoring point are threaded into the same threading hose 8, so that the plastic threading hose 8 with a lining inside is used to effectively protect the cables of the sensors and prolong the service life. Unlike the first sensor system, since the second sensor system and the collection box 10 are arranged at the shaft door section 3, the cables in the threading hose 8 of the second sensor system can not pass through the junction box 9, but are directly connected with the collection box 10.

[0043] Further, in some embodiments of the present application, the box body of the collection box 10 is suspended on the concrete wall on the main shaft door side of the shaft door section 3 by expansion screws, the box body of the collection box 10 is made of stainless steel plate and is subjected to explosion-proof, rust-proof and corrosion-proof treatment in order to cope with the harsh construction environment underground. The collection box 10 is internally provided with a collection module, a wired transmission module and a wireless transmission module connected with the collection module, the collection module is used to connect with the cables of the sensors, collect the corresponding sensing signals, and the wired transmission module and the wireless transmission module are respectively used to transmit the collected sensing signals through different signal transmission modes. In the present application, each module in the collection box 10 is a conventional functional module, and the specific accessories selected can be selected from existing accessories according to the needs of actual conditions, and the present application is not limited thereto. For example, the collection module can select a multi-channel collector and a serial port server, wherein the number of channels of the multi-channel collector can be configured according to the number of sensors connected; the wired transmission module can select a switch, and the wireless transmission module can select a router, and the collection box 10 can further be provided with an optical-electricity converter and a transformer, and the power supply in the collection box 10 can use the ground pressure lighting electricity of the shaft door.

[0044] Further, in some embodiments of the present application, the communication module includes an optical cable 11 connected with the wired transmission module and a wireless receiving module 12 connected with the wireless transmission module. Among them, the optical cable 11 can be selected as an industrial armored communication optical cable 11, and the length needs to be sufficient to connect the ground and the target horsehead door. In actual application, the optical cable 11 can be bundled with the monitoring, telephone line and other cables of the vertical shaft construction party, suspended and lowered by the steel wire rope, fixed by the wire hoop while lowering, so that the optical cable 11 is closely attached to the steel wire rope to ensure stability. After the optical cable 11 is lowered to the target horsehead door, the optical cable 11 is connected to the acquisition box 10, so as to be connected with the wired transmission module in the acquisition box 10. The ground end of the optical cable 11 needs to be reserved with sufficient length, so as to be connected to the ground receiving box 14 and the dispatching room computer 15. The wireless receiving module 12 can be arranged at the air return port of the wellhead, so as to realize wireless connection with the wireless transmission module in the acquisition box 10 under the ground. The wireless receiving module 12 can also be connected with the ground receiving box 14 through the optical cable 11. In the present application, the wireless receiving module 12 is a conventional functional module, and its wireless communication protocol can be selected as Lora or 4G mode according to needs. In addition, since the transmission distance of the wireless transmission module in the acquisition box 10 is limited, a repeater 13 can be installed at the horsehead door at the intermediate position, so as to ensure stable transmission of the wireless signal.

[0045] Further, in some embodiments of the present application, the ground receiving box 14 can be installed on the outer wall of the ground building. The ground receiving box 14 is provided with a power supply, a receiving module and a transmitting module. The receiving module and the transmitting module are conventional functional modules, which can be selected according to actual needs in existing products, and can realize signal receiving and transmitting. Among them, the receiving module can be connected with the optical cable 11 in the communication module for receiving wired signals, and can also be connected with the wireless receiving module 12 in the communication module through the additional optical cable 11 for receiving wireless signals. The signals received by the ground receiving box 14 can be directly connected to the dispatching room computer 15, or can be interconnected with the 4G signal through the transmitting module, and the information can be transmitted to the cloud server through the Internet, so that the user can view the monitoring data on any computer.

[0046] By the above manner, the in-construction super-deep vertical shaft ground pressure monitoring system can make the monitoring system more integral, can monitor the super-deep vertical shaft ground pressure in multiple sections synchronously, and realizes full coverage of the shaft 1 full-deep ground pressure monitoring area. Meanwhile, the cable of the sensor arranged in each section can be effectively protected by the threading hose 8, effectively prolonging the service life. Moreover, the data transmission in the application has both wired and wireless transmission modes, providing double insurance for data uploading and ensuring stable transmission of monitoring data. On this basis, the sensor system, the acquisition box 10 and the like in the in-construction super-deep vertical shaft ground pressure monitoring system can work for a long time, realizing comprehensive, real-time, long-term and stable monitoring of the in-construction super-deep vertical shaft ground pressure.

[0047] It should be noted that the present application is not limited to the above embodiments.
