Problems solved by technology

[0002] Rock drilling jumbo is an important mechanical equipment for tunnel drilling and blasting mechanized construction. The quality of contour forming is one of the important control indicators of tunnel blasting. Excessive over- and under-excavation of rock mass will increase the cycle time, and even large-scale rework. Proper drilling The design of the blasting hole pattern and the drilling operation are crucial to improving the blasting effect. When the drilling rig is working, the actual drilling operation of the drilling rig may not be consistent with the preset hole layout. Figure 1 As a result, the drilling quality of key drilling and blasting holes is often unsatisfactory, resulting in excessive over- and under-excavation defects in the tunnel contour after blasting. Therefore, it is very important to check and control the drilling quality. There is no detection method and system for drilling quality

Embodiment 1

[0024] A method for evaluating the drilling quality of a rock drilling rig, comprising: acquiring a hole layout map and a simulation map of a tunnel profile after simulating blasting according to the hole layout map; During the setting operation, the attitude data of each rock drilling arm of the rock drilling rig is obtained, and then the actual drilling and blasting hole distribution map is obtained; after blasting, the tunnel outline is scanned to obtain the actual tunnel outline; The distribution map of drilling and blasting holes, the simulation map of the tunnel profile and the actual tunnel profile map, perform over-under-excavation analysis, and obtain the analysis results, which are used to evaluate the drilling quality and blasting quality of the rock drilling rig.

[0025] like Figure 1~Figure 3 As shown, the rock drilling rig includes a traveling chassis 1, a cab 2, a wing boom 3, an outrigger 4, a drilling arm 5 and a platform arm 6 installed on the traveling cha...

Embodiment 2

[0034] Based on the method for evaluating the drilling quality of a rock drilling rig described in Embodiment 1, this embodiment provides a drilling quality evaluation system for a rock drilling rig, including: a first module for acquiring a hole layout map and according to the hole layout The second module is to obtain the attitude data of each rock drilling arm of the rock drilling rig when the drilling rig performs the drilling and blasting operation according to the obtained hole layout diagram, and then Obtain the actual distribution map of drilling and blasting holes; the third module is used to scan the tunnel contour after blasting to obtain the actual tunnel contour map; The contour simulation diagram and the actual tunnel contour diagram are used to analyze the over and under excavation, and obtain the analysis results, which are used to evaluate the drilling quality and blasting quality of the rock drilling rig.

Embodiment 3

[0036] Based on the method for evaluating the drilling quality of a rock drilling rig described in Embodiment 1 and the system for evaluating the drilling quality of a rock drilling rig described in Embodiment 2, this embodiment provides a drilling method for a rock drilling rig, including: obtaining The hole layout diagram and the simulation diagram of the tunnel profile after the blasting is simulated according to the hole layout diagram; when the rock drilling rig performs the drilling and blasting operation according to the obtained hole layout diagram, the drilling rigs of each rock drilling arm of the rock drilling rig are obtained. attitude data, and then obtain the actual drilling and blasting hole distribution map; after blasting, scan the tunnel contour to obtain the actual tunnel contour map; based on the hole layout map, the actual drilling and blasting hole distribution map, the tunnel contour simulation map and the actual tunnel contour Based on the analysis resul...

Abstract

The invention discloses a drilling rig drilling method, a drilling quality evaluation method and system, and a rock drilling rig in the technical field of rock drilling rigs. The simulation diagram of the tunnel profile after blasting is simulated according to the hole layout diagram; when the rock drilling rig performs the drilling and blasting operation according to the obtained hole layout diagram, the attitude data of each rock drilling arm of the rock drilling rig is obtained, and then Obtain the actual drilled and blasted hole distribution map; after blasting, scan the tunnel outline to obtain the actual tunnel outline map; based on the hole layout map, the actual drilled and blasted hole distribution map, the tunnel outline simulation map and the actual tunnel outline map, carry out the supervising. Underexcavation analysis to obtain analysis results for evaluating the drilling quality and blasting quality of the rock drilling rig. It can effectively improve the drilling quality of the rock drilling rig and the contour quality after blasting.

Description

technical field [0001] The invention belongs to the technical field of rock drilling rigs, and particularly relates to a drilling method for a rock drilling rig, a drilling quality evaluation method and system, and a rock drilling rig. Background technique [0002] The rock drilling rig is an important mechanical equipment for the mechanized construction of tunnel drilling and blasting method. The quality of contour forming is one of the important control indicators for tunnel blasting. Excessive and under-excavation of the rock mass will increase the cycle time, and even large-scale rework. The design of blasting hole layout and drilling operation are very important to improve the blasting effect. When the drilling rig is working, the actual drilling operation of the drilling rig may not be able to match the preset hole layout. Figure 1 As a result, the drilling quality of key drilling and blasting holes is often unsatisfactory, resulting in excessive and under-excavation d...
