Description

Technical Field

[0001] The invention belongs to the technical field of coal mine gas control, and in particular relates to a method for quickly verifying a drilling orientation in a given area. Background Art

[0002] Regional verification is a key step in coal mine gas control and outburst prevention (coal and gas outburst prevention and control). Its core goal is to accurately determine whether the coal seam area meets the conditions for safe excavation. A hole attitude meter is required for construction area verification. A hole attitude meter is a high-precision instrument used to measure the attitude of a drill hole. It is widely used in underground coal mine drilling rigs, geological exploration, and other fields. During regional verification, a hole attitude meter is often used to measure the inclination of the drill hole.

[0003] However, the use of the hole attitude meter has the following problems:

[0004] 1) High cost: Aperture attitude meters rely on high-precision MEMS sensors or fiber optic gyroscopes, and core components are primarily imported. A single device typically costs tens to hundreds of thousands of yuan, and requires supporting professional data processing software (some of which require subscription fees), increasing long-term operating costs. Furthermore, high humidity environments can easily damage electronic components, shortening the instrument's lifespan and requiring long and expensive repair and replacement cycles.

[0005] 2) Poor portability: The explosion-proof and shock-proof design results in a bulky casing, often weighing more than 5kg, making it difficult to move underground; some models require connection to a mine power supply, limiting construction flexibility;

[0006] 3) Complex operation: Underground conditions are harsh, and the attitude meter needs to be calibrated frequently, but there is a lack of stable reference points. At the same time, data interpretation requires professionals, and ordinary miners may misjudge the drilling angle. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a method for quickly verifying the drilling orientation in a given area.

[0008] The technical solution adopted by the present invention is a method for quickly verifying the drilling orientation in a given area, which is:

[0009] S1. Using trigonometric functions and a steel tape measure, determine the parameters of the 2-meter to 4-meter contour line for the area verification and create a parameter table.

[0010] S2. Use a tape measure to measure the position 0.5m away from the left and right sides of the tunnel;

[0011] S3. Keep the drill rod horizontal and perpendicular to the working surface at a distance of 0.5m from the left and right sides of the tunnel, and then shift the tail of the drill rod left and right;

[0012] S4. Use a tape measure to measure the distance between the drill pipe tail and the working surface and the auxiliary surface after deviation;

[0013] S5. Determine the distance between the tail of the drill pipe and the working surface and the auxiliary surface by referring to the parameter table to obtain the opening angle and the range of the control tunnel contour line.

[0014] Furthermore, the parameters of the regional verification of the 2m to 4m contour line include the outer length of the 10m verification hole control tunnel contour line, the distance from the drill pipe tail to the side surface, and the distance from the drill pipe tail to the working surface.

[0015] Compared with the existing technology, the beneficial effect of the present invention is that the present invention only requires a steel tape measure and a parameter table, and the angle and control range can be obtained by measuring the position of the drill rod from the working surface according to the parameter table. There is no need to operate the instrument, and there is no need to purchase supporting professional data processing software. It is light and practical and can be carried with you. In addition, the operation is simple, no professional training is required, anyone can easily operate it, it is not affected by the environment, and no calibration is required.
