Abstract
The invention discloses a kind of measurement methods of large-scale break-though roadways, belong to collery's surface movement prevention and treatment and field of measuring technique；The following steps are included: the two sides in tunnel determine starting point A and B respectively；Total station is erected at starting point A, flatten centering, traverse point known to backsight measures three points on the final bottom edge in break-though roadways one end, in point B, flatten centering, traverse point known to backsight measures three points on the final bottom edge in break-though roadways one end, arbitrarily selects any point between starting point and final bottom edge point only to flatten in forward sight, according to the most preceding middle line measuring point point 7 in two tunnels and point g coordinate according to calculated by coordinate method, the azimuth of a little 7 and point g is found out；The present invention shortens the time of underground leveling centering；Simplify the tissue of work；It improves work efficiency；Reduce the labor intensity of underground survey personnel；Plane and measurement of higher degree precision are effectively increased, measurement error is reduced.
Description
Technical field
The invention belongs to collery's surface movement prevention and treatment and field of measuring technique, are related to a kind of suitable for the unrestrained water of underground coal mine
Application technology in the process, the spy discharge method and device of specially a kind of coal mine overlying rock water.
Background technique
The measurement of tunnel and down-hole is different from ground surface works measurement there are many measurement method of multiplicity, underground coal mine by
It is limited in by its special space and operating environment, measurement method is also subject to certain restrictions, the measurement hand of underground coal mine
Section and method are single, tunnel and underground survey can only with the extension forward of working face, constantly extend forward in, stringcourse, survey
Amount method is limited only to polar coordinates traverse method.Simultaneously because underworkings fluctuations, the distance of traverse point is irregular, to measurement
Cause certain error.
Summary of the invention
Encountered measurement difficulty is big, and the big problem of measurement error provides in order to solve to measure in underground coal mine by the present invention
A kind of measurement method of large-scale break-though roadways.The present invention is achieved through the following technical solutions.
A kind of measurement method of large size break-though roadways, comprising the following steps:
1) starting point A and B are determined respectively in the two sides in tunnel.
2) total station is erected at starting point A, flattens centering, traverse point known to backsight measures break-though roadways one end most
Three points are set as a little 5, point 6, point 7 with the sequence of tunnel side wall to center line in roadway by three points on whole bottom edge.
3) total station is erected at starting point B, flattens centering, traverse point known to backsight measures break-though roadways one end most
Three points are set as point e, point f, point g with the sequence of tunnel side wall to center line in roadway by three points on whole bottom edge.
4) it arbitrarily selects any point between starting point and final bottom edge point only to flatten in forward sight, to the last reaches eventually
When putting 5,6,7 or point e, f, g, it need to be flattened to neutralizing.
5) according to the most preceding middle line measuring point point 7 in two tunnels and point g coordinate according to calculated by coordinate method, find out a little 7 and point g's
The distance of azimuth angle alpha 7 and α g and point 7 and point g to starting point A.
6) according to point 7 compared with the grid azimuth α 5 of two break-though roadways, α 6, α f, α g, and respectively to two break-though roadways
Orientation be adjusted to α g and α 7.
Down-hole measure traverse line point is often arranged in the tight roof in tunnel, and leveling centering uses centring under point, by
Shorter, distinguished and admirable larger in underground polygon leg, instrument and surveyor's beacon centering angle measurement and survey side have an impact.Before saving a method in the present invention
Viewpoint can not need to retain optionally in position, without centering is not required to, only need to flatten.
The present invention is generated compared with the existing technology to be had the beneficial effect that.
The present invention is starting point using the permanent pilot point of setting, installs instrument in starting point, known to backsight
Traverse point installs pedestal and prism with band in apparatus for leveling in preceding apparent direction, and instrument is only flattened and misaligned, in measurement
It in pilot process, also only flattens, misaligns, on the middle line or traverse point in last attached to two tunnels to be penetrated through.The present invention
Shorten the time of underground leveling centering；Simplify the tissue of work；It improves work efficiency.Reduce the labor of underground survey personnel
Fatigue resistance；Plane and measurement of higher degree precision are effectively increased, measurement error is reduced.
Detailed description of the invention
Fig. 1 is the measurement point schematic diagram of the large-scale break-though roadways of the present invention.
Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, in conjunction with reality
Example and attached drawing are applied, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to
It explains the present invention, is not intended to limit the present invention.Below with reference to the examples and drawings technical solution that the present invention will be described in detail, but
The scope of protection is not limited by this.
As shown in Figure 1, a kind of measurement method of large size break-though roadways, comprising the following steps:
1) starting point A and B are determined respectively in the two sides in tunnel.
2) total station is erected at starting point A, flattens centering, traverse point known to backsight measures break-though roadways one end most
Three points are set as a little 5, point 6, point 7 with the sequence of tunnel side wall to center line in roadway by three points on whole bottom edge.
3) total station is erected at starting point B, flattens centering, traverse point known to backsight measures break-though roadways one end most
Three points are set as point e, point f, point g with the sequence of tunnel side wall to center line in roadway by three points on whole bottom edge.
4) arbitrary point between starting point and final bottom edge point, including point 1, point 2, point 3, point 4, point are arbitrarily selected in forward sight
A, point b, point c, point d are only flattened, to the last reach home 5,6,7 or point e, f, g when, need to neutralize flatten.
5) according to the most preceding middle line measuring point point 7 in two tunnels and point g coordinate according to calculated by coordinate method, find out a little 7 and point g's
The distance of azimuth angle alpha 7 and α g and point 7 and point g to starting point A.
6) according to point 7 compared with the grid azimuth α 5 of two break-though roadways, α 6, α f, α g, and respectively to two break-though roadways
Orientation be adjusted to α g and α 7.
The above content is combine specific preferred embodiment to the further description done of the present invention, and it cannot be said that
A specific embodiment of the invention is only limitted to this, for those of ordinary skill in the art to which the present invention belongs, is not taking off
Under the premise of from the present invention, several simple deduction or replace can also be made, all shall be regarded as belonging to the present invention by being submitted
Claims determine scope of patent protection.
