Embodiment Construction
[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail in combination with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. The technical solutions of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings, but the scope of protection is not limited thereto.
[0016] Such as figure 1 As shown, a measurement method for a large through roadway, including the following steps:
[0017] 1) Determine the starting points A and B on both sides of the roadway respectively.
[0018] 2) Set up the total station at the starting point A, level and center it, look back at the known wire points, and measure the three points passing through the f...

The invention discloses a measuring method for a large break-through roadway, and belongs to the technical field of coal mine geological disaster prevention and measurement. The method comprises the following steps that starting points A and B are determined on the two sides of the roadway respectively; a total station is erected at the starting point A, leveling and centering are performed, existing guide line points are subjected to rear view processing, and three points of the final bottom edge of one end of the break-through roadway are measured; at the point B, the leveling and centeringare performed, the existing guide line points are subjected to the rear view processing, and the three points of the final bottom edge of one end of the break-through roadway are measured; any point between the starting point and the final bottom edge point is randomly selected at a front view, and the leveling is performed only; and according to coordinates of center line measuring points 7 and gin the forefront of two roadways, and based on a coordinate inverse calculation method, the azimuth angles of the points 7 and g are calculated out. The time of underground leveling and centering isshortened; the work organization is simplified; the work efficiency is improved; the labor intensity of underground measurement personnel is reduced; and the measurement precision of plane and elevation is effectively improved, so that the measurement error is reduced.
Description
technical field [0001] The invention belongs to the technical field of prevention and measurement of geological disasters in coal mines, and relates to an application technology applicable to the process of draining water underground in coal mines, in particular to a method and device for detecting and draining water in overlying strata of coal mines. Background technique [0002] Underground measurements in tunnels and mines are different from ground engineering measurements in that there are various measurement methods. Underground coal mines are limited by their special space and operating environment, and their measurement methods are also subject to certain restrictions. The measurement methods and methods in underground coal mines are single , Tunnel and downhole measurement can only extend forward along with the working face, and continue to extend the middle and waistline forward, and its measurement method is limited to the polar coordinate traverse method. At the s...
