Description

The Contact triangle measurement method that a kind of down-hole adjacent wires is obstructed

Technical field

The invention belongs to mining survey technical field, the triangle contact particularly relating to a kind of down-hole adjacent wires obstructed is surveyed Mensuration.

Background technology

Mining survey is different from other surveying, especially underworkings as an independent subject and measures, and wire is surveyed Amount is its uniqueness, and therefore the continuity at control point becomes the characteristic that underground construction controls.

Along with increase and the improvement of mining methods of this mine life, the coming off of control point, people in old tunnel Destruction to back control point at the bottom of work vacation, causes the seriality of wire to be destroyed, and leverages and measures opening of work Exhibition.

Mine construction follows limit mining, the principle of limit mine locating substantially, measures control point and is once destroyed, and integrated wire net is extensive Get up again extremely difficult.

Along with the development of science and technology, mining methods there has also been the biggest improvement, in order to obtain most ore deposits as far as possible Amount and safer mining mode, mine uses advanced " Man-made False is without ore pillar filling " mining methods, this method pair Production and safety efficiency significantly improves.But this method is the biggest to the destruction of SURVEYING CONTROL NETWORK, and Controling network is owing to wanting along the pulse Do " Man-made False " tunnel topside control sites the most destroyed, therefore make traverse net disconnect and cannot use, at underworkings (especially Old tunnel) measurement in, often encounter situations below: traverse point is destroyed, drop or wire that roadway support causes The situation of point not intervisibility occurs.In the recent period, along with the development of science and technology, mining methods have had the biggest improvement, in order to not lose Ore deposit is measured and creates safer mining environment, and mine have employed " Man-made False is without ore pillar filling " mining methods of advanced person, this The efficiency of production and safety is obviously improved by the method for kind, but owing to false top is made at top, drift by this method, therefore to setting Put and destroy serious at the measurement control point at top, tunnel, later measurement and other work using control point are produced disadvantageous Impact.

Summary of the invention

For solving the problems referred to above present in prior art and practical situation, the invention provides a kind of down-hole adjacent wires Obstructed Contact triangle measurement method, comprises the following steps:

1) junction point will be increased between two known lead points of not intervisibility, make junction point and two known points be formed with even Contact is the triangle on summit；

2) junction point and the horizontal range of two known points, junction point and the angle of two known point lines are measured；

3) extrapolate two other acute angle by sine, be allowed to meet angle sum of a triangle through adjustment and be equal to 180 °, then Coordinate figure inverse according to two known points goes out the azimuth of two known points, and thus the orientation of junction point is extrapolated at azimuth Angle；

4) coordinate of junction point is extrapolated according to the coordinate of the orientation of known point to junction point, distance and known point, then by connecting The coordinate of point and junction point are extrapolated another known point coordinate to the azimuth-range of another known point and are checked, then Carry out precision estimation, if meet engineering construction requirement.

The present invention uses succinctly and method accurately, does not affect production.As the workshop of 2000 tons of Ores of daily output, The utilization rate in its tunnel is the highest, can effectively be reduced the time taking tunnel because of measurement by the method, and Can quickly solve the progress of underground construction, also mitigate the workload of down-hole mapping worker simultaneously.

The inventive method is used only to need within about 1 hour, just to complete conventional 12 workaday measurement workloads.This Kind of method not only solves the labor intensity problem of mapping worker but also improves construction and the efficiency produced, and reduce because of Measure and take the time in tunnel, meet the mapping requirement of " technically feasible, precision to allow, reasonable in economy ".

Accompanying drawing explanation

Fig. 1 is the plane measured drawing of the obstructed Contact triangle measurement method of the down-hole adjacent wires of the embodiment of the present invention.

Detailed description of the invention

Technical solution of the present invention is discussed in detail below in conjunction with the accompanying drawings.

Embodiment of the invention discloses that the Contact triangle measurement method that a kind of down-hole adjacent wires is obstructed, including following step Rapid:

1) junction point will be increased between two known lead points of not intervisibility, make junction point and two known points be formed with even Contact is the triangle on summit；

2) junction point and the horizontal range of two known points, junction point and the angle of two known point lines are measured；

3) extrapolate two other acute angle by sine, be allowed to meet angle sum of a triangle through adjustment and be equal to 180 °, then Coordinate figure inverse according to two known points goes out the azimuth of two known points, and thus the orientation of junction point is extrapolated at azimuth Angle；

4) coordinate of junction point is extrapolated according to the coordinate of the orientation of known point to junction point, distance and known point, then by connecting The coordinate of point and junction point are extrapolated another known point coordinate to the azimuth-range of another known point and are checked, then Carry out precision estimation, if meet engineering construction requirement.

Illustrate as a example by the gallery measured drawing of stage casing section, km well mining area 725 below:

Step one: as it is shown in figure 1,27' to No. 29 point is known point in figure, and not intervisibility；Unknown point is arranged between these 2 B so that 27'-B, 29-B intervisibility, forms triangulation chain.

Step 2: unknown point B in measured drawing and the angle β angle of two known point lines, actual quantities B-27' and the water of B-29 Flat distance, table 1 is surveying record table.
