Description

[0002] In underground surveying, it is often necessary to mark the opening location and direction of the tunnel, and the center line is usually marked at the positive excavation tunnel position. There are many mining tunnels in the underground mining area, which are evenly arranged in a straight line from the main tunnel to the ore vein. During the construction process, the main tunnel is first excavated and formed, and then the adjacent mining tunnels are excavated. The engineering quality of each mining tunnel is directly related to the safety of mining operations in the later stage.

[0003] In the relevant technology, when excavating the opening section of each mining tunnel, since the main tunnel is close to the opening face, the center waistline point calibrated in the positive direction is easily damaged by blasting, which makes it impossible to calibrate the center line and waistline normally. As a result, the measurement workload is increased by relying on measurement and layout after each blast. The surveying and mapping process is cumbersome and time-consuming, affecting the progress of the project construction. If the center line and waistline are not determined accurately, it will cause quality accidents such as tunnel deviation, under-excavation or over-excavation. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] According to an embodiment of the present invention, an embodiment of a method for controlling the quality of the middle waistline of a transition section of a cutting tunnel opening is provided. It should be noted that although the steps shown in the flowchart of the accompanying drawings are shown in a logical order in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown here.

[0020] This embodiment provides a method for controlling the quality of the middle waistline of the transition section of the opening of the mining tunnel. Figure 1 As shown, the method comprises the following steps: S101. Based on the tunnel construction measurement elements, determine the center line and waist line of the tunnel excavation direction.

[0021] Specifically, determining the center line and waist line of the tunnel excavation direction based on the tunnel construction measurement elements refers to measuring and determining the center line and waist line of the formed main tunnel based on the tunnel construction measurement elements such as the bottom plate involved in the formed main tunnel and the tunnel opening direction. Usually, the center line is arranged in the vault area of ​​the excavated tunnel, and the waist line is marked at the tunnel opening, at a preset height upward from the bottom plate, such as one meter. This embodiment does not make specific limitations on this, and it can be set according to actual working conditions.

[0022] S102. Based on the waistline, a measuring instrument is used to determine a first fixed point with a side wall corresponding to the opposite direction of the tunnel excavation direction.

[0023] Specifically, based on the waistline, a measuring instrument is used to determine the first fixed point with the side wall corresponding to the opposite direction of the tunnel excavation direction. This means that the waistline point is determined at a preset height in the tunnel excavation direction through the determined waistline, and a measuring instrument is used to determine a measuring point at the same height from the waistline point to the main tunnel floor on the side wall corresponding to the opposite direction of the tunnel excavation direction, i.e., the first fixed point.

[0024] S103. Based on the center line and the first fixed point, a second fixed point is determined on the side wall using a measuring instrument.

[0025] Specifically, based on the center line and the first fixed point, using a surveying instrument, determining the second fixed point on the side wall means setting a second point above the side wall to which the first fixed point belongs, and using a surveying instrument to make the second point be along the center line, so that the first fixed point and the second point belong to the same horizontal plane, thereby taking the second point as the second fixed point. The distance between the corresponding point of the second fixed point and the first fixed point is generally within two meters, usually in the range of 0.5 to 0.8 meters, to facilitate surveying personnel to set points and perform drilling operations. Figure 2 As shown, the positions of the first fixed point and the second fixed point are exemplarily shown. It should be understood that the positions of the first fixed point and the second fixed point include but are not limited to Figure 2 As shown, the first fixed point and the second fixed point are both located in the side wall area where the side wall is vertical to the bottom plate in the opposite direction of the tunnel excavation direction.

[0026] S104. Based on the center line, use a measuring instrument to determine at least one third fixed point in the arched area of ​​the side wall.

[0027] Specifically, based on the center line, using a measuring instrument, at least one third fixed point is determined in the arched area of ​​the side wall. This means that at least one third point is arranged in the arched area of ​​the side wall, and the position of the third point is along the center line, so that the first fixed point and each third point belong to the same horizontal plane, and the third point is used as the third fixed point. The corresponding point of the third fixed point is generally located more than two meters above the arched line of the side wall, and the distance between adjacent third fixed points is kept within one meter. By adding at least one third fixed point, when any third fixed point is affected by blasting damage, part of the point is blocked, and the accuracy of the center line cannot be guaranteed. Therefore, multiple third fixed points are added as backup center lines. Among them, the arched area of ​​the side wall refers to the range above the arched line of the side wall. This area is arc-shaped, such as Figure 2 As shown, two third fixed points are shown exemplarily. It should be understood that the positions of the third fixed points include but are not limited to Figure 2 As shown, the third fixed points are all within the arched area of ​​the side wall.

[0028] S105. Perform quality control on tunnel excavation based on the first fixed point, the second fixed point, and the third fixed point.

[0029] Specifically, quality control of tunnel excavation based on the first fixed point, the second fixed point, and the third fixed point means using the first fixed point as a waistline marking point, using a measuring instrument as the waistline, and adjusting the slope of the tunnel excavation direction, and using the first fixed point, the second fixed point, and the third fixed point together as centerline fixed points, and using a measuring instrument to adjust the tunnel excavation direction and position.

[0030] The present invention provides a method and device for controlling the quality of the middle waistline of the opening transition section of a mining tunnel. The method determines the middle line and waistline of the tunnel, and uses the side wall corresponding to the waistline in the opposite direction of the tunnel excavation direction to determine a first fixed point, and then determines a second fixed point on the side wall and a third fixed point located in the arching area of ​​the side wall, so as to control the quality of the tunnel excavation. In this process, the first fixed point is determined by using the side wall corresponding to the waistline in the opposite direction of the tunnel excavation direction as the point corresponding to the middle waistline, and the second fixed point and the third fixed point determined by the middle line are used as the points corresponding to the middle line, so as to use the side wall to determine the middle line and waistline fixed points, avoid point damage and influence caused by the excavation process, omit tedious repeated measurement work, complete the quality control of the tunnel excavation, and avoid the occurrence of quality accidents.

[0031] In an optional implementation, based on the waistline, using a measuring instrument, determining the first fixed point with a side wall corresponding to the opposite direction of the tunnel excavation direction includes: Based on the waistline, a waistline point is determined at a preset height in the tunnel excavation direction; based on the waistline point, a first fixed point is determined on a side wall corresponding to the opposite direction of the tunnel excavation direction using a measuring instrument.

[0032] Specifically, based on the waistline, at a preset height in the tunnel excavation direction, determining the waistline point means determining the waistline point in the tunnel excavation direction at the same height as the waistline. For example, if the waistline is marked at a preset height upward from the tunnel opening floor, such as one meter, then the waistline point is located one meter upward from the tunnel opening floor.

[0033] Specifically, based on the waistline point, using a measuring instrument, determining the first fixed point on the side wall corresponding to the opposite direction of the tunnel excavation direction means using a measuring instrument to extend the waistline in reverse parallel to the determined waistline point position until the position of the first fixed point is determined on the side wall corresponding to the opposite direction of the tunnel excavation direction. The measuring instrument can be a total station or other measuring instrument, as long as it can be used to ensure that the waistline point and the first fixed point are at the same distance from the bottom plate, that is, to ensure that when measuring at the waistline point, it is extended in reverse parallel to the side wall corresponding to the opposite direction of the tunnel excavation direction. Figure 2 As shown, Figure 2 The dotted line between the position of the first fixed point and the tunnel opening represents the process of extending the waistline in reverse parallel until the position of the first fixed point is determined on the side wall corresponding to the opposite direction of the tunnel excavation direction.

[0034] In an optional implementation, quality control of tunnel excavation is performed based on the first fixed point, the second fixed point, and the third fixed point, including: Based on the first fixed point, use a measuring instrument to adjust the slope of the tunnel excavation direction; based on the first fixed point, the second fixed point, and the third fixed point, use a measuring instrument to form a first ray, a second ray, and a third ray in the tunnel excavation direction, respectively; based on the first ray, the second ray, and the third ray, adjust the tunnel excavation direction and position.

[0035] Specifically, based on the first fixed point, using a measuring instrument, adjusting the slope of the tunnel excavation direction means using a measuring instrument to extend the waistline in parallel at the determined first fixed point until the waistline position is determined at a position corresponding to the tunnel excavation direction, thereby judging whether the slope is within a reasonable range through the waistline position and the distance from the first fixed point to the bottom plate, and adjusting the slope in the excavation direction.

[0036] Specifically, based on the first fixed point, the second fixed point and the third fixed point, a measuring instrument is used to respectively form a first ray, a second ray and a third ray in the direction of tunnel excavation. This means that a measuring instrument is used to measure in the direction of tunnel excavation at the first fixed point, the second fixed point and the third fixed point to respectively form the first ray, the second ray and the third ray.

[0037] In an optional implementation, adjusting the tunnel excavation direction and position based on the first ray, the second ray, and the third ray includes: Determine whether the first ray, the second ray, and the third ray belong to the same horizontal plane; in response to the first ray, the second ray, and the third ray belonging to the same horizontal plane, do not adjust the tunnel excavation direction and position.

[0038] Specifically, in response to the first ray, the second ray, and the third ray belonging to the same horizontal plane, not adjusting the tunnel excavation direction and position means using whether the first ray, the second ray, and the third ray belong to the same horizontal plane to determine whether the tunnel has a direction and position shift during the excavation process, that is, when the first ray, the second ray, and the third ray belong to the same horizontal plane, there is no shift in the tunnel excavation direction and position; otherwise, there is a shift and the relevant shift needs to be corrected.

[0039] In an optional implementation, based on the center line and the first fixed point, using a measuring instrument, determining a second fixed point on the side wall includes: Based on the center line, a point distribution area is determined using a measuring instrument; based on the intersection of the point distribution area and a preset distance between the first fixed point, a second fixed point is determined on the side wall.

[0040] Specifically, determining the point distribution area based on the center line using a measuring instrument means determining the point distribution area at a corresponding position of the side wall along the center line direction using a measuring instrument.

[0041] Specifically, based on the intersection of the preset spacing between the point distribution area and the first fixed point, determining the second fixed point on the side wall means determining the intersection with the point distribution area at the preset spacing above the first fixed point, that is, arranging the second point, and since the second point is projected along the centerline direction and is located above the first fixed point, the position of the second point is along the centerline direction, and the first fixed point and the second point belong to the same horizontal plane, so the second point is used as the second fixed point. The preset spacing is generally within two meters, usually in the range of 0.5 meters to 0.8 meters.
