A kind of non-contact measurement method of Slope Angle for Open pit Mines
Technical field
The present invention relates to a kind of non-contact measurement method of Slope Angle for Open pit Mines, relate in particular to and a kind ofly realize the method to open slope angle Accurate Determining based on luminous point ranging technology and angle measurement technique.
Background technology
At present, by side, exploitation is just extensively carried out at glory-hole, very strict for the requirement of side slope angle by side exploitation.Open-pit slope is to excavate by mining the tall and big complex slope forming, can be divided into working slope, non-working slope and end side according to the difference of operation property, working slope side slope is owing to being subject to the disturbance of winning apparatus, cause Slope Shape fragmentation, structure very irregular, the loose easy cunning of edge slope structure being formed by interior casting operation, manually cannot be close.Therefore, be difficult to measure accurately the angle of open-pit slope.
Summary of the invention
For the problem of above-mentioned prior art existence, the invention provides a kind of non-contact measurement method of Slope Angle for Open pit Mines, based on the calculating of range finding, angle measurement and trigonometric function, Obtaining Accurate Slope Angle for Open pit Mines.
To achieve these goals, the technical solution used in the present invention comprises the following steps:
A: horizontal positioned distance measuring equipment and angle-measuring equipment on square position, ore deposit side slope bottom in the open, angle-measuring equipment is fixed on distance measuring equipment;
B: utilize distance measuring equipment to measure its horizontal range L apart from bench toe
1;
C: rotation distance measuring equipment is to aiming at required measuring point;
D: the distance L of measuring distance measuring equipment and measuring point
2;
E: the angle [alpha] of obtaining distance measuring equipment rotation by angle-measuring equipment;
F: utilize trigonometric function principle to calculate side slope angle beta.
Preferably, described distance measuring equipment adopts electro-optical distance instrument.
Preferably, described distance measuring equipment is the distance measuring equipment with levelling function.
Preferably, the precision of described distance measuring equipment is ± 1cm.
Preferably, the precision of described angle-measuring equipment is 0.2 °, and useful range is 180 °.
The invention has the beneficial effects as follows: the ultimate principle that the present invention is based on distance, angle and trigonometric function, the Accurate Determining method of measuring complicated open-pit slope is provided, by being used in conjunction with of distance measuring equipment and angle-measuring equipment, obtain and the parameter of side slope Angular correlation, and then geometric analysis calculates side slope angle.Application cost of the present invention is low, simple to operate, calculates, for the definite and production safety of exploitation boundary provides technical guarantee by the measurement of side slope angle.
