Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, specifically relating to an integrated online monitoring and early warning device for fissure water hazards in underground mines, which can simultaneously detect water inflow, water temperature, water pressure, and water quality. Background Technology

[0002] Domestic mine water hazard monitoring systems primarily monitor borehole water levels, mine drainage volumes, and water tank levels in real time. For fissure water hazard monitoring, single-factor or static monitoring methods are commonly used, such as electrical resistivity tomography (EDT) and microseismic monitoring. EDT monitors changes in mine fissure water by measuring changes in the electrical properties of the underground medium; however, it is susceptible to external influences, such as external magnetic fields and the electrical characteristics of the monitored object. Microseismic monitoring detects changes in fissure water by monitoring minute vibrations within the rock mass; however, it is also susceptible to changes in the physical properties and geological structure of the underground rock.

Detailed Implementation

[0022] To facilitate understanding and implementation of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to embodiments. The embodiments described herein are only for illustration and explanation and are not intended to limit the present utility model.

[0023] Example 1:

[0024] An integrated online monitoring and early warning device for fissure water hazards in underground mines includes an early warning device comprising a cylindrical protective shell 1, a water temperature detection probe 4, a water pressure detection probe 5, a water collection pipe 8, and a flow meter 9. The protective shell 1 includes an insertion end and an early warning end. The early warning end of the protective shell 1 is provided with an outward-facing fixing ring 2, which has a fixing hole 3. The insertion end of the protective shell 1 is inserted into a water detection hole installed in the rock wall, and the early warning device is then fixed in the water detection hole through the fixing hole 3 on the outward-facing fixing ring 2. The water temperature detection probe 4 and the water pressure detection probe 5 are... On the outer side of the insertion end of the protective housing 1, a water temperature detection probe 4 and a water pressure detection probe 5 are respectively used for water temperature detection and water pressure detection; a water collection tank 7 is also provided in the protective housing 1, which is connected to the outlet of the water collection pipe 8. The water inlet of the water collection pipe 8 is provided on the insertion end of the protective housing 1, and the water collection tank 7 is connected to the inlet of the water discharge pipe 10. The outlet of the water discharge pipe 10 is provided on the warning end of the protective housing 1. A water quality detection probe 6 is provided in the water collection tank 7. Valves are also provided on the water collection pipe 8 and the water discharge pipe 10. A flow meter 9 (such as an ultrasonic flow meter) is also provided on the water collection pipe 8.

[0025] Water samples from the fissures are collected through the water collection pipe 8 and the flow meter 9 on the water collection pipe 8 measures the flow rate. The water is then stored in the water collection tank 7 for water quality testing, thus enabling periodic testing. Water samples from the fissures can also be collected and released to the outside through the water discharge pipe 10. The outward-folding fixing ring 2 on the protective shell 1 can better install the early warning device inside the water detection hole.

[0026] In one embodiment, the system also includes a data transceiver 11 and an external communication device 12. The water temperature detection probe 4, water pressure detection probe 5, flow meter 9, water quality detection probe 6, valve of the water collection pipe 8, and valve of the water discharge pipe 10 are all connected to the data transceiver 11 via data cables. The data transceiver 11 is connected to the external communication device 12 via data cables. The external communication interface (such as an LTE interface) of the external communication device 12 is located at the warning end of the protective casing 1. A wireless communication device is connected to the external communication interface or connected to an external monitoring system via a signal transmission line. The data transceiver 11 receives various measurement data of the fissure water, including water temperature, water pressure, flow rate, and water quality, and transmits each measurement data to the external monitoring system via the external communication device 12. The monitoring personnel compare each measurement data with the threshold of each warning level corresponding to the measurement data and send a warning signal of the corresponding warning level to the data transceiver 11.

[0027] The data transceiver 11 is also connected to the valves of the water collection pipe 8 and the water discharge pipe 10 via a data cable. External monitoring personnel send control signals of the valves of the water collection pipe 8 and the water discharge pipe 10 to the data transceiver 11. The data transceiver 11 adjusts the opening and closing of the valves of the water collection pipe 8 and the water discharge pipe 10 by receiving the control signals.

[0028] In one embodiment, the device further includes an audible and visual alarm 13, which includes a signal light 14 and a buzzer 15. Both the signal light 14 and the buzzer 15 are disposed on the outer side of the warning end of the protective housing 1. Both the signal light 14 and the buzzer 15 are connected to the data transceiver 11. After receiving the warning signal, the data transceiver 11 sends the warning signal to the audible and visual alarm 13. After receiving the warning signal, the audible and visual alarm 13 alarms the corresponding warning level through the signal light 14 and the buzzer 15. For example, the signal light 14 alarms the different warning levels by flashing at different frequencies, and the buzzer 15 alarms the different warning levels by blaring at different frequencies.

[0029] In one embodiment, a power module 16 is also included to power the early warning device. The power module 16 is connected to the data transceiver 11, the water quality detection probe 6, the water temperature detection probe 4, the water pressure detection probe 5, the valve of the water collection pipe 8, and the valve of the water discharge pipe 10 via power lines.

[0030] The early warning device of this utility model integrates a flow meter 9, a water temperature detection probe 4, a water pressure detection probe 5, and a water quality detection probe 6. It can simultaneously detect the inflow, water temperature, water pressure, and water quality. Furthermore, each probe of this utility model is in direct contact with and samples the fissure water in the water detection hole, avoiding interference from external environmental factors such as rock physical properties and ensuring the accuracy of water source measurement results.

[0031] The early warning device of this utility model has a modular structure, so if a probe or module malfunctions, it can be quickly replaced.

[0032] It should be noted that the embodiments described in this utility model are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described embodiments or use similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
