With the advancement of science and technology, the mining and utilization methods of coal mines are also constantly innovating to meet the needs of sustainable development. In the process of coal mine production, the problem of groundwater on the roof and floor of the tunnel is inevitable, and the existence of groundwater also brings many safety hazards to coal mine production. Therefore, the tunnel floor drainage system is directly related to the work safety of the staff.

[0003] At present, the existing coal mine tunnel floors are usually drained by drainage units in conjunction with drainage pipe extraction methods. However, in the above drainage method, the drainage units are basically in a normally open state, and lack real-time and reliable detection of water at the floor position (i.e., lack of detection data support), and cannot flexibly set the drainage power in response to changes in water accumulation on the floor, resulting in a large overall energy consumption of the floor drainage system and a large deviation in the drainage control of the floor; in addition, the existing floor drainage system also lacks feedback on the drainage situation and accident alarms, making it impossible for staff to obtain drainage information and accident alarms in a timely manner, which is not conducive to safety work and real-time monitoring in the mine.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a tunnel floor drainage system, including: a drainage well 10, a floor detector 20, a drainage channel 30, a drainage unit 40, a drainage pipeline 50, a water level detection component 60 and an intelligent controller. The drainage well 10 is arranged in the floor of the tunnel and extends deep into the stratum. The drainage well 10 is used to collect water on the floor of the tunnel; the floor detector 20 is arranged on the floor and is used to detect the water level change on the floor; the drainage channel 30 is arranged on the floor and is connected to the drainage well 10, and is used to guide the water on the floor to flow into the drainage well 10; the drainage unit 40 is arranged In the drainage well 10, the drainage pipe 50 is connected to the outside of the tunnel and the drainage unit 40 respectively, and the drainage unit 40 discharges the water in the drainage well 10 to the outside of the tunnel through the drainage pipe 50; the water level detection component 60 is arranged in the drainage well 10, and is used to detect the water level height in the drainage well 10; the bottom plate detector 20, the drainage unit 40, and the water level detection component 60 are electrically connected to the intelligent controller respectively, and the intelligent controller controls the operation of the drainage unit 40 according to the water level changes on the bottom plate detected by the bottom plate detector 20 and the water level height in the drainage well 10 detected by the water level detection component 60.

[0029] The present invention realizes reliable drainage of the floor of the tunnel and real-time and reliable detection of water on the floor by setting a drainage well 10, a floor detector 20, a drainage channel 30, a drainage unit 40, a drainage pipeline 50, a water level detection component 60 and an intelligent controller to work together, so that the intelligent controller can flexibly set the drainage power according to the changes in the water accumulation on the floor in real time according to the data obtained by the detection, thereby making the overall energy consumption of the tunnel floor drainage system reasonable and reducing the deviation of the drainage control of the floor; subsequently, by setting and expanding the function of the intelligent controller, real-time feedback on the drainage situation and timely alarm for accidents can be realized, thereby structurally ensuring safe work and real-time monitoring in the mine; by setting the drainage well 10 and the drainage channel 30 to work together, the water on the floor can be Reliable recovery, which is convenient for subsequent reuse of water, avoiding waste of water resources; the tunnel floor drainage system proposed in the present invention has been found to be efficiently applied to coal mines in actual use. The present invention, combined with other existing detection equipment, communication equipment and display equipment, can collect, transmit information, analyze and process various real-time dynamic data in the tunnel, remotely monitor, control decisions and prevent and warn, thereby realizing the automation, informatization and intelligence of drainage in coal mine tunnels, improving the operating efficiency of the drainage system, reducing the operating cost of the drainage system, improving the safety and reliability of the drainage system, increasing the scope of application of the drainage system, extending the service life of the drainage system, and playing a role in ensuring the safe operation of coal mine production; the present invention has a simple structure and low cost, is easy to form and subsequent maintenance, and is suitable for large-scale promotion and use.

[0030] like Figure 1 As shown, drainage wells 10 are arranged at the sides of the tunnel to avoid the passage of personnel and equipment in the tunnel; there are multiple drainage wells 10, and multiple drainage wells 10 are arranged at intervals along both sides of the tunnel; there are multiple drainage channels 30, and at least one drainage channel 30 connects two adjacent drainage wells 10.

[0031] By setting up multiple drainage wells 10 on both sides of the lane, interference with the passage of personnel and equipment is avoided, ensuring that the passage of the lane is not affected by drainage facilities, and improving the safety and passage efficiency of the lane. At the same time, multiple drainage wells 10 and connected drainage channels 30 increase the drainage capacity and flexibility of the system, can more effectively and quickly handle groundwater in different locations, prevent local water accumulation, and further improve the overall efficiency of the drainage system.

[0032] like Figure 1 As shown, at least one of the multiple drainage channels 30 extends along the extension direction of the alley, and the extension direction of at least one drainage channel 30 is perpendicular to the extension direction of the alley; there are multiple drainage pipes 50, and at least one of the multiple drainage pipes 50 is buried under the bottom plate and extends along the extension direction of the alley.

[0033] This arrangement increases the rationality of the layout of the drainage channel 30 and the drainage pipeline 50, can more comprehensively cover the bottom plate of the tunnel, and ensure that groundwater can be fully collected and quickly discharged; the drainage channel 30 and the drainage pipeline 50 arranged along the extension direction of the tunnel improve the drainage efficiency of the system, and the drainage channel 30 perpendicular to the extension direction of the tunnel helps to collect groundwater on both sides of the tunnel, prevent water from accumulating laterally along the tunnel, and ensure the overall drainage performance of the system.

[0034] like Figure 2 As shown, the water level detection component 60 includes an instant water level detection structure 61 and a safety water level detector 62, and the instant water level detection structure 61 and the safety water level detector 62 are electrically connected to the intelligent controller respectively; the instant water level detection structure 61 is used to detect the water level height in the drainage well 10 in real time; the safety water level detector 62 is arranged in the drainage well 10 and is located at a set safety water level height; wherein, when the water level in the drainage well 10 rises to the safety water level height, the safety water level detector 62 is contacted by water and triggered; the intelligent controller detects the water level change speed according to the instant water level detection structure 61, and calculates the reduced water flow rate according to the water level change speed and the size of the drainage well 10. When the reduced flow rate is greater than the drainage flow rate of the drainage unit 40 at this time, the intelligent controller determines that the water in the drainage well 10 is leaking and sends out a leakage alarm message.

[0035] By setting up a double-layer detection mechanism of an instant water level detection structure 61 and a safety water level detector 62, it is possible to monitor the water level changes in the drainage well 10 in real time, and trigger an alarm when the water level reaches a preset safety height, thereby ensuring the safe operation of the drainage system; the intelligent controller can calculate the reduced water flow rate based on the water level change rate, and can promptly identify and issue a leakage alarm when the reduced flow rate is abnormal, which not only improves the system's responsiveness to abnormal situations, but also reduces potential safety hazards.

[0036] Specifically, when the water level in the drainage well 10 rises to the safe water level, the safe water level detector 62 is triggered by water contact. If the water level detected by the real-time water level detection structure 61 is greater than or equal to the safe water level, the intelligent controller issues a high water level alarm message and controls the drainage unit 40 to perform drainage at maximum power. If the water level detected by the real-time water level detection structure 61 is less than the safe water level, the intelligent controller issues an abnormal alarm message to remind the staff to observe the water level in the drainage well 10 at this time.

[0037] This arrangement can ensure that when the water level rises abnormally, the drainage unit 40 can immediately start drainage at maximum power, avoiding the safety risk of excessively high water levels; at the same time, an abnormal alarm can also be issued for the situation where the water level is lower than the safe water level, prompting the staff to check the working status of the drainage system, avoiding poor drainage due to system failure, and further enhancing the stability and safety of the drainage system.

[0038] like Figure 2 As shown, the real-time water level detection structure 61 includes: a floating guide rod 611, a floating member 612 and a height detector 613; the floating guide rod 611 is fixedly arranged on the inner wall of the drainage well 10 and is vertically arranged, and the floating member 612 is slidably arranged on the floating guide rod 611 and floats on the water surface in the drainage well 10 to follow the rise and fall of the water level; the height detector 613 is electrically connected to the intelligent controller, and the height detector 613 detects the height change of the water level in the drainage well 10 in real time by detecting the height change of the floating member 612.

[0039] By setting the floating member 612 to follow the rise and fall of the water level, the accuracy and real-time nature of the water level detection are ensured; the height detector 613 monitors the water level in the drainage well 10 in real time by detecting the height change of the floating member 612, and provides accurate data support for the intelligent controller, making the control of the drainage unit 40 more precise, which not only improves the drainage efficiency, but also reduces unnecessary energy waste.

[0040] Specifically, the tunnel floor drainage system also includes a plurality of safety permeable gratings, which respectively cover the opening of the drainage well 10 and the exposed opening of the drainage channel 30; the safety permeable gratings are used to prevent external equipment or workers from falling into the drainage well 10 and the drainage channel 30, and allow water on the floor to pass through.

[0041] The setting of the safety permeable grille can not only prevent external equipment or workers from falling into the drainage well 10 and the drainage channel 30, thereby ensuring the safety of personnel in the tunnel, but also allow water on the bottom plate to pass smoothly without affecting the drainage process, thereby ensuring the safety and reliability of the system.

[0042] Optionally, the tunnel floor drainage system further includes a filter screen, which is provided in a plurality of ways and arranged in the drainage well 10 and the drainage channel 30, respectively. The filter screen is used to prevent foreign matter from entering the drainage well 10 and the drainage channel 30 to avoid blockage. Figure 1 As shown, there are multiple bottom plate detectors 20, and the multiple bottom plate detectors 20 are arranged at intervals along the extension direction of the tunnel to respectively detect water level changes at different positions on the bottom plate.

[0043] The setting of the filter net can effectively prevent foreign objects from entering the drainage well 10 and the drainage channel 30, reduce the possibility of system blockage, extend the service life of the equipment, and reduce maintenance costs; the layout of multiple bottom plate detectors 20 increases the coverage and accuracy of water level detection, and can more accurately monitor the water level changes at different positions of the bottom plate, provide more comprehensive data for the intelligent controller, and enhance the intelligence and automation control capabilities of the drainage system.

[0044] Specifically, there are multiple drainage wells 10, and the total volume of water that can be accommodated by the multiple drainage wells 10 is a first volume V. The time required for the staff to completely evacuate the tunnel is statistically obtained as the first time t. The maximum flow rate when groundwater leaks in the tunnel is statistically obtained as the first flow rate n, V≥t*n, so as to ensure that the staff can safely evacuate the tunnel when the drainage unit 40 is completely out of operation.

[0045] By ensuring that the total volume of the drainage well 10 is large enough, it can accommodate the water generated by groundwater leakage even if the drainage unit 40 fails, providing a safe time window for emergency evacuation of staff and greatly improving the safety of the tunnel drainage system in emergency situations.

[0046] The present invention also provides a tunnel floor drainage method, which is applied to the above-mentioned tunnel floor drainage system, and the tunnel floor drainage method also includes the following steps: drainage layout step: based on the geological conditions of the tunnel, a drainage channel 30 and a drainage well 10 are excavated in the floor, a drainage unit 40, a drainage pipeline 50 and a water level detection component 60 are installed in the drainage well 10, and the drainage pipeline 50 is connected to the outside of the tunnel; a plurality of floor detectors 20 are installed on the floor to respectively detect water level changes at different positions on the floor; data acquisition step: the intelligent controller obtains water level change data on the floor according to the detection of the floor detector 20, and the intelligent controller obtains drainage data according to the detection of the water level detection component 60 The water level height data in the water well 10 controls the drainage unit 40 to work at the corresponding power according to the water level change data and the water level height data; when the water level detection component 60 detects that the water level in the drainage well 10 rises to the safe water level, the intelligent controller issues a high water level alarm message and controls the drainage unit 40 to drain at the maximum power; the intelligent controller detects the water level change speed according to the water level detection component 60, and calculates the reduced water flow rate according to the water level change speed and the size of the drainage well 10. When the reduced flow rate is greater than the drainage flow rate of the drainage unit 40 at this time, the intelligent controller determines that the water in the drainage well 10 is leaking, and issues a leakage alarm message to remind the staff to pay attention to whether the leaked water softens the bottom plate.

[0047] The above method realizes the intelligent management of the drainage system through scientific drainage layout and data collection; the intelligent controller dynamically adjusts the power of the drainage unit 40 according to the real-time monitored water level changes and height data, reduces energy consumption, and improves the economy and environmental protection of the system; when the water level rises abnormally, the intelligent controller can immediately activate the alarm and adjust the drainage strategy, ensuring the safe and stable operation of the system, while promoting the safety and efficiency of coal mine production.

[0048] In summary, the present invention provides a tunnel floor drainage system and a tunnel floor drainage method. The present invention realizes reliable drainage of the tunnel floor and real-time and reliable detection of water on the floor by setting a drainage well 10, a floor detector 20, a drainage channel 30, a drainage unit 40, a drainage pipeline 50, a water level detection component 60 and an intelligent controller to work together, so that the intelligent controller can flexibly set the drainage power according to the changes in the water accumulation on the floor in real time according to the data obtained by the detection, thereby making the overall energy consumption of the tunnel floor drainage system reasonable and reducing the deviation of the drainage control of the floor; subsequently, by setting and expanding the function of the intelligent controller, real-time feedback on the drainage situation and timely alarm for accidents can be realized, thereby structurally ensuring safe work and real-time monitoring in the mine; by setting the drainage well 10 and the drainage channel 30 The coordinated work realizes the reliable recovery of water on the bottom plate, which is convenient for the subsequent reuse of water and avoids the waste of water resources; the tunnel bottom plate drainage system proposed in the present invention has been found to be efficiently applied to coal mines in actual use. The present invention is combined with other existing detection equipment, communication equipment and display equipment to collect, transmit information, analyze and process various real-time dynamic data in the tunnel, remotely monitor, control decisions and prevent and warn, thereby realizing the automation, informatization and intelligentization of drainage in coal mine tunnels, improving the operating efficiency of the drainage system, reducing the operating cost of the drainage system, improving the safety and reliability of the drainage system, increasing the scope of application of the drainage system, extending the service life of the drainage system, and playing a role in ensuring the safe operation of coal mine production; the present invention has a simple structure and low cost, is easy to form and subsequent maintenance, and is suitable for large-scale promotion and use.
