Abstract
The invention discloses an extension measuring orientation method of a mine shaft well under a separating layer. The extension measuring orientation method of the mine shaft under the separating layer comprises a coordinate measuring step and a gyroscopic total station measuring orientation step; the coordinate measuring step is characterized in that shaft-bottom three-layer buntons cross curve and well coordinate before extension of a shaft well are measured on the spot, a mean value is taken as the well cross curve and the well coordinate on the separating layer; a gyroscopic total station can be used for transferring a control point coordinate to a tunnel undetermined point under the separating layer by a lead measuring manner through measurement engineering, orientation of the gyroscopic total station is carried out, the coordinate of the undetermined point is transmitted to the well coordinate under the separating layer; the a gyroscopic total station measuring orientation step is characterized in that two control point azimuth angles are measured in a tunnel on the separating layer by the gyroscopic total station, the cross curve azimuth angels and the well coordinate are measured, the undetermined point azimuth angles are measured under the separating layer, and then the cross curve azimuth angels and the well coordinate under the separating layer are lofted. The transmission of the coordinate azimuth angles has the advantages of high precision and fast speed, is advanced and reliable, and has little influence by other factors.
Description
Technical field
The invention belongs to vertical shaft for mine under a kind of sealing coat and extend measurement orientation method.
Background technology
The indirect deepening of mine engineering vertical shaft is a special Control Surveying in High Accuracy, and for ensureing the indirect deepening quality of vertical shaft, measuring method must be accurate, and ensures that precision is in regulating scope, makes every effort to precision more high more good simultaneously.
Owing under Shaft extension sealing coat, certainty of measurement is required higher by installing engineering, it is desirable to the quality of survey crew azimuthal, coordinate transmission strictly controls. Traditional azimuthal coordinates transmission method: a kind of method is to measure 3-5 layer on sealing coat namely to have buntons analytical Calculation to go out namely to have coordinate in the shaft cross line and well, being delivered under sealing coat at sealing coat upper surface drill hole of drilling machine by coordinate in cross hairs orientation and well instructs installing engineering to measure, this kind of method is due to by the restriction of execution conditions in pit shaft, take the pit shaft time longer, borehole throw is relatively big, not easily reaches code requirement; Another kind of method, adopting traverse survey method to be delivered under sealing coat by azimuth and coordinate in setting-out well cross hairs by measures engineering (gallery-interior shaft or inclined shaft-gallery) on coordinate in the well of analytical Calculation instructs installing engineering under sealing coat to measure, the method is due to the impact by factors such as measures engineering conversion and angle measurement, instrument centering, range measurements, and azimuth transmission is beyond installation specification requirement. For these reasons, it is very important for formulating advanced technology measurement orientation method, now adopts a kind of method of science to measure azimuth and coordinate.
Summary of the invention
The technical problem to be solved in the present invention is to overcome drawbacks described above, there is provided vertical shaft for mine under a kind of sealing coat to extend and measure orientation method, transmission grid bearing angular accuracy height, speed are fast, advanced reliable, less by the impact of other factors, solve boring orientation and traverse survey transmission azimuth accuracy problem low, slow-footed.
For solving the problems referred to above, the technical solution adopted in the present invention is:
Under a kind of sealing coat, vertical shaft for mine extends measurement orientation method, it is characterised in that: include measurement of coordinates step, gyroscope total station measures orientation step; Described measurement of coordinates step, with reference to former the shaft cross line design load and measured value, coordinate in field survey Shaft extension front shaft bottom three layers buntons cross hairs and well, averages as namely there being coordinate in the shaft cross line and well on sealing coat; Utilize gyroscope total station to be delivered to sealing coat under tunnel point to be located by measures engineering in traverse survey mode by control point coordinate, the coordinate of point to be located is delivered to after gyroscope total station orientation sealing coat again and goes into the well middle coordinate; Described gyroscope total station measures orientation step, namely gyroscope total station is measured has two azimuths, control point in tunnel on sealing coat, and measure and namely have coordinate in cross hairs azimuth and well, measure two point to be located azimuths under sealing coat, then coordinate in setting-out sealing coat well-sinking cross hairs and well.
Owing to have employed technique scheme, compared with prior art, namely the present invention has buntons to determine coordinate in the shaft cross line and well for measuring on vertical shaft sealing coat, utilize orientation and the coordinate of the control point gyroscope total station surveyor's cross namely having in tunnel, the point to be located that will namely have coordinate to be delivered under sealing coat tunnel, gyroscope total station measures coordinate in the azimuth of point to be located setting-out sealing coat well-sinking cross hairs and well.
The present invention transmits grid bearing angular accuracy height, speed is fast, advanced person is reliable, less by the impact of other factors, solves boring orientation and azimuth accuracy problem low, slow-footed is transmitted in traverse survey.
