Description

Technical Field

[0001] This invention belongs to the field of borehole attitude measurement technology, and more specifically, relates to a borehole attitude measurement device and its usage method in roadways. Background Technology

[0002] As the mainstay of my country's energy structure, coal mining is a crucial pillar of socio-economic development. Leveraging its low cost and high reserves, it powers key industries such as electricity, steel, and chemicals, ensuring national energy security and economic stability, while simultaneously driving innovation and breakthroughs in mining technology, clean utilization, and intelligent operations. With the depletion of shallow resources, my country's coal mining has gradually shifted towards deeper layers, and tunnel drilling is the foundation for rock exploration, stress monitoring, gas extraction, and tunnel support in deep mining.

[0003] In measuring the strike and dip of boreholes in coal mine roadways, commonly used inclinometers, total stations, and traditional compasses have significant limitations. For example, inclinometers are constrained by borehole diameter and accessibility; small-diameter, collapsed, or curved boreholes are prone to probe jamming, affecting data integrity. Total stations rely on borehole opening measurements, making it difficult to reflect deep trajectory offsets, and coordinate conversion can easily amplify errors.

Detailed Implementation

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The outer casing includes a first outer casing 10 and a second outer casing 20, which are connected. For example, the first outer casing 10 and the second outer casing 20 can be detachably connected. The first outer casing 10 is a transparent casing, and the second outer casing 20 is a metal casing. That is, the first outer casing 10 is a transparent casing made of a transparent material, and the second outer casing 20 is a metal, opaque casing made of a metal material. Optionally, the first outer casing 10 can be made of transparent glass; however, it is not limited to this, as long as the first outer casing 10 is made of a transparent material, it can be, but is not limited to, glass.

[0030] Optionally, the metal casing can be made of aluminum, aluminum alloy, copper, copper alloy, or other materials. Preferably, the metal casing is made of aluminum alloy.

[0031] In the borehole attitude measurement device, the conical mirror 30 is disposed inside the first outer shell 10; that is, the conical mirror 30 is correspondingly disposed inside the transparent outer shell, which covers the outside of the conical mirror 30. The main function of the conical mirror 30 is to reflect the condition of the borehole inner wall. For example, the borehole quality can be reflected by the conical mirror 30 through the transparent outer shell; the main function of the conical mirror 30 is to reflect the condition of the borehole inner wall.

[0032] By reflecting the borehole wall through the conical mirror 30, a panoramic image can be obtained in one go without mechanical rotation, enabling real-time and high-speed observation of the borehole wall. It features high efficiency, no moving parts, no splicing errors, and high real-time performance. Therefore, the conical mirror 30 has excellent performance in application scenarios that require rapid, comprehensive, and dynamic observation of the borehole wall.

[0033] In the borehole attitude measurement device, camera 40 is housed within the second outer casing 20, that is, camera 40 is housed inside a metal casing, which covers the outside of camera 40, and camera 40, located inside the metal casing, is positioned opposite to conical mirror 30, located inside a transparent casing. Camera 40 is mainly used for real-time monitoring of conical mirror 30. For example, during the measurement process when the measuring device is placed in the borehole, camera 40 can continuously capture and record images of the borehole inner wall reflected by conical mirror 30, so as to facilitate subsequent evaluation of borehole quality or rock mass fracture conditions.

[0034] Optionally, in this embodiment, the conical mirror 30, camera 40, data storage and transmission unit 50, and measurement unit 60 are all located inside the housing, and the conical mirror 30, camera 40, at least a portion of the data storage and transmission unit 50, and at least a portion of the measurement unit 60 are coaxially arranged.

This data storage and transmission unit 50 is electrically connected to the camera 40. The data storage and transmission unit 50 can be used to store images captured by the camera 40 and transmit them to relevant devices, such as computers or other related processing equipment.

[0036] In the borehole attitude measurement device, the measurement unit 60 is housed within the second outer casing 20, that is, the measurement unit 60 is housed inside a metal casing, which covers the outside of the measurement unit 60. The measurement unit 60 is electrically connected to the data storage and transmission unit 50. The data storage and transmission unit 50 can also be used to transmit the data measured by the measurement unit 60. The data measured by the measurement unit 60 can be transmitted through the data storage and transmission unit 50 to related equipment, such as computers or other related processing equipment.

[0037] Therefore, the provided borehole attitude measurement device mainly consists of a borehole quality assessment module and a borehole attitude measurement module. The borehole quality assessment module is primarily implemented through a transparent housing, a conical mirror 30, a camera 40, and a data storage and transmission unit 50. For example, the borehole inner wall fractures can be reflected on the conical mirror 30 (e.g., a metal conical mirror) through the transparent housing (e.g., a transparent glass housing), and the camera 40 (e.g., a miniature industrial camera) records the borehole inner wall image on the conical mirror 30 in real time. The borehole attitude measurement module is primarily implemented through a measurement unit 60 (e.g., an electronic compass) and the data storage and transmission unit 50. The measurement unit 60 can be used to measure the borehole's dip and inclination angle. Thus, the configuration of the conical mirror 30, camera 40, and transparent housing enables borehole quality assessment, and the configuration of the measurement unit 60 enables borehole attitude measurement. This achieves the effect of not only measuring borehole attitude but also assessing borehole quality, and is applicable to boreholes of different diameters. In addition, this measuring device overcomes the shortcomings of inaccurate measurements in traditional monitoring equipment, and can deduce the entire borehole orientation information by measuring data from specific points.

It operates in conjunction with the vertical electronic compass 620, and together they form a north-south coordinate system, which can display the borehole's orientation, dip, and rotation angle in real time. For example, regarding hollow-cell strain gauges, the measuring device can install the hollow-cell strain gauge at the top.

[0063] The borehole attitude measurement device in this embodiment is a three-dimensional mining stress sensor based on borehole micro-deformation monitoring technology, which includes a borehole quality assessment module and a borehole attitude measurement module.

[0064] When using this tunnel borehole occurrence measurement device, a hole can be drilled in the rock mass, relevant sensors can be installed on the top of the measurement device, the mounting rod can be assembled on the bottom of the measurement device, the entire device can be pushed into the borehole, and the borehole quality and occurrence can be measured at intervals.

[0065] Accordingly, in some embodiments, a method of using a roadway borehole attitude measuring device is provided, the method comprising: The borehole attitude measurement device is connected to a sensor to form a measurement device, which is then sent into the borehole; for example, it is connected to the external sensor through a first detachable connector 810 on the top outer side of the transparent housing to form a measurement device. The condition of the borehole inner wall is reflected on the conical mirror 30 through the transparent shell. The camera 40 captures the image of the borehole inner wall on the conical mirror 30 in real time. The data storage and transmission unit 50 stores and processes the image of the borehole inner wall captured by the camera 40. The dip and inclination of the borehole are measured by the measuring unit 60; for example, the dip and inclination of the borehole are measured by the coordinated use of the horizontal electronic compass 610 and the vertical electronic compass 620. The measuring device is gradually pushed into the hole, and the tendency and inclination of the borehole are measured at preset intervals until it is pushed to the bottom of the hole.

[0066] In this embodiment, the measuring device is used to drill holes in the rock mass, connect other sensors to the top of the measuring device, insert the entire measuring device into the hole, measure the hole's inclination and dip angle, and slowly push the measuring device into the hole, measuring the hole's inclination and dip angle at fixed intervals until it is pushed to the bottom of the hole.

[0067] For example, when the measuring device is used to assess the quality of a borehole, the condition of the borehole's inner wall is captured by the metal conical mirror 30 through the transparent glass shell as the measuring device is pushed into the borehole. The miniature industrial camera 40 captures the image of the borehole's inner wall on the metal conical mirror 30 in real time. After the sensor installation is completed, the measuring device is pulled out. By exporting the image of the borehole's inner wall monitored by the miniature industrial camera 40, processing such as conical image unfolding and distortion processing is performed. Finally, the quality of the borehole can be assessed through the image, such as assessing the development of cracks in the borehole.

[0068] For example, when this measuring device is used to measure borehole attitude, after the measuring device is inserted into the borehole, the measuring device switch is turned on. The horizontal electronic compass 610 and the vertical electronic compass work together to monitor the attitude. The horizontal electronic compass 610 is mainly used to measure the borehole's strike, while the vertical electronic compass 620 is mainly used to measure the borehole's dip and the measuring device's rotation angle. The two electronic compasses together construct a northeast-central coordinate system. Measurements are taken at intervals during insertion into the measuring device, ultimately measuring both the borehole's strike and dip. After data export, the borehole's azimuth is obtained by transforming the northeast-central coordinate system, thus achieving the measurement of the borehole's attitude.
