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

Abstract

The invention discloses a drill jumbo drilling method, a drilling quality evaluation method and system, as well as a drill jumbo, and belongs to the technical field of drill jumbos. The drill jumbo drilling quality evaluation method comprises the steps that a hole distribution diagram is obtained, and a tunnel contour simulation diagram after blasting is simulated according to the hole distribution diagram is obtained; when the drill jumbo conducts drilling and blasting hole drilling operation according to the obtained hole distribution diagram, posture data of all drill arms of the drill jumbo are obtained, and then an actual drilling and blasting hole distribution diagram is obtained; after blasting, the tunnel contour is scanned to obtain an actual tunnel contour map; and based on the hole distribution diagram, the actual drilling and blasting hole distribution diagram, the tunnel contour simulation diagram and the actual tunnel contour diagram, back break analysis is conducted, and an analysis result is obtained and is used for evaluating the drilling quality and blasting quality of the drill jumbo. The drilling quality of the drill jumbo and the contour quality after blasting can be effectively improved.
