Embodiment Construction

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0026] In one embodiment of the present invention, comprise the following steps:

[0027] Step 1, determine the bearing area of ​​the blasthole, and determine the minimum resistance line (determining the minimum resistance line needs to be confirmed according to the nature of the rock, the blasting material and the blasting form, the specific method is the prior art in this field, and no specific details will be made here Discussion) and determine the direction of the first row of holes and the position of the first blast hole, the first row of holes and the distance between the first row of holes and the nearest free surface is greater than or equal to the minimum resistance line;

[0028] Step 2, set up the total ...

Abstract

The invention relates to a method for setting out holes for a total station, comprising the following steps: step 1, determining the bearing area of ​​blastholes, and determining the direction of the first row of holes and the position of the first blasthole; step 2, setting up the total station on On the first blasthole position, and adjust the horizontal height of the detection port of the total station; Step 3, after completing the erection work of the total station, the erection position coordinates of the total station are set to (0,0,0), Align the detection port of the total station with the direction of the first row of hole layout, and set the horizontal angle of the total station to zero; step 4, call the relative coordinate data file of the blast hole corresponding to the area of ​​the blast hole, and set it in the total station Set the hole distance and hole layout distance, and use the stakeout function of the total station to mark the blasthole position corresponding to the hole position data in the explosion area to complete the stakeout hole layout. The invention realizes simple and rapid hole layout in any explosion zone environment, and makes the hole layout uniform and regular, reduces the labor intensity of hole layout, and improves the efficiency of hole layout.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a method for setting out and arranging holes for a total station. Background technique [0002] The drilling and blasting operation is to use the energy generated by the explosion of explosives to act on the rocks around the blasthole to break the rocks. Since the damage range of the explosives to the rocks is limited, and a reasonable hole row spacing can make reasonable use of the energy of the explosives, so that Rocks are adequately broken and avoid over breaking. Therefore, the level of the drilling quality will directly affect the blasting effect, and an important factor affecting the drilling quality is the hole layout accuracy. In the process of blasting construction, measuring ropes are generally used to arrange holes, and the terrain in the blasting area is uneven, often because the measuring ropes are in a tilted state and stretched, the error of the blasthole spacin...
