Embodiment 1

[0038] like Figure 1~Figure 4 As shown, a device and method for real-time automatic monitoring of old empty water in coal mines is characterized in that it includes a steel pipe 1, a steel sleeve 2, a steel plate A 3 and a steel plate B 4, a pressure sensor 5, a temperature sensor 6, a pH sensor 7, Water hardness sensor 8, TDS tester 9, ORP meter 10, signal receiver 11 and controller 12; pressure sensor 5, temperature sensor 6, pH sensor 7, water hardness sensor 8, TDS tester are arranged on the outer surface of steel pipe 1 Meter 9, ORP meter 10, these test elements are connected with signal receiver 11 respectively, receive signal by signal receiver 11 and deliver to controller 12 and carry out data processing;

[0039] There is an annular cavity between the steel pipe 1 and the steel sleeve 2, and the above-mentioned test components are located in the cavity. The steel pipe 1 and the steel sleeve 2 are cylinders with the same height and are coaxial. Steel plate A3 is prov...

Embodiment 2

[0051] The real-time automatic monitoring coal mine old air water regime method of the present invention is used in the well as follows (such as Figure 6 Shown): In a mine with a low mining depth, a hole 13 is drilled vertically downward from the ground to the goaf, and the diameter of the hole 13 is 320mm; sent to the goaf IV, the device fell to the bottom of the goaf IV due to its own weight; after the device was sent in, the borehole 13 was blocked with cement-water glass grouting slurry 14 to slow down the weathering of the cable and the hole The damage to the cable caused by the wall collapse and avoid the exposure of the borehole 13 to the surface; by adjusting the controller 12, the water regime in the goaf IV is monitored every 15 days. If there is an abnormality in each parameter, the observation data will be automatically encrypted (1 times / min).

[0052] All the other are with embodiment 1.

Embodiment 3

[0054] The real-time automatic monitoring coal mine old air water regime method of the present invention is used in the coal seam mining process as follows: after the coal seam mining is completed, a monitoring device 15 of the present invention is placed in the coal seam goaf; by adjusting the controller 12, The water regime in the goaf is monitored every 30 days, and if any abnormality occurs in each parameter, the observation data will be automatically encrypted (1 time / min).

[0055] All the other are with embodiment 1.

Abstract

The invention discloses a device and a method for monitoring a water regimen of goaf water of a coal mine automatically in real time. The device comprises a steel pipe, a steel jacket, a steel plate A, a steel plate B, testing components, a signal receiver and a controller. A pressure sensor, a temperature sensor, a pH sensor, a water quality hardness sensor, a TDS tester and an ORP meter are arranged on the outer surface of the steel pipe. The testing components are connected to the signal receiver, separately and are transferred to the controller by the signal receiver. An annular cavity isformed between the steel pipe and the steel jacket, the testing components are located in the cavity, the steel pipe and the steel jacket are cylinders equal in height and are coaxial, the steel plateA is arranged on the tops of the steel pipe and the steel jacket, and the steel plate B is arranged at the bottoms of the steel pipe and the steel jacket. Mine water penetrating holes are uniformly formed in the surfaces of the steel jacket and the steel plate, and wiring holes are formed in the steel plates. The device can monitor the water regimen of goaf water automatically in real time, alsocan set the monitoring time manually, and has the advantages of being high in efficiency, high in anti-interference capacity, small in project quantity, low in cost and the like.

Description

technical field [0001] The invention relates to a device and a method for monitoring old empty water in coal mines, in particular to a real-time automatic monitoring device and method for old empty water in coal mines, and belongs to the technical field of coal mine safety mining. Background technique [0002] Mine water damage is one of the five major disasters in mines, and its damage to mines is second only to gas, ranking second. The types of mine water damage can be divided into roof water damage, floor water damage, old hollow water damage, fault and subsidence column water damage, and poorly sealed borehole water damage. Among them, old empty water damage is the main type of water damage that threatens the safe production of coal mines. After coal mining is completed, a large number of abandoned roadways and coal mining spaces will be left underground. At this time, due to the stop of drainage in the mine, a large amount of groundwater will accumulate in the goaf. Thi...
