Embodiment 1

[0082] Such as Figure 1 to Figure 9 As shown, the present embodiment provides a rapid construction system for side rock bolt holes and advanced drilling in the excavation working face, including a bolter 1, an onboard drilling rig 2 arranged on the top platform of the bolter 1, a shuttle car 3, The lower airborne drilling rig 5 and the control system are arranged at the tail of the shuttle car 3 through the limit adjustment device 4; wherein, the upper airborne drilling rig 2 is used for the construction of the upper row of bolt holes and advanced drilling in the roadway of the excavation working face, and the lower machine The drilling rig 5 is used for the construction of the lower row of bolt holes in the two sides of the roadway, and the control system is used for the automatic control of the drilling construction of the drilling rig.

[0083] Such as figure 2 As shown, the upper airborne drilling rig 2 includes: a rotary mechanism A21, a secondary feeding device A22 ar...

Embodiment 2

[0102] This embodiment provides a method for rapid construction of the side rock bolt holes on the excavation working face, the method includes the rapid construction of the upper row of bolt holes on the side of the excavation face by the upper airborne drilling rig and the lower row of anchor rods by the lower airborne drilling rig Hole rapid construction;

[0103] Such as Figure 5 and Figure 6 , the steps of construction of the upper row of bolt holes by the upper airborne drilling rig include:

[0104] A1: Adjust the angle adjustment cylinder group to complete the opening angle positioning of the upper row of bolt holes on the left side of the roadway;

[0105] A2: When the onboard drilling rig is constructing the upper row of bolt holes, the bolt drilling rig that comes with the bolter is also constructing the bolt holes, so select the power control mode of mode 1 for the onboard drilling rig to ensure that the upper The construction of the airborne drilling rig does...

Embodiment 3

[0120] This embodiment provides a rapid construction method for advanced drilling in the excavation working face. The advanced drilling includes a water exploration hole, a regional verification hole and a coal seam water injection hole;

[0121] On C, the airborne drilling rig constructs the excavation work face and explores the water hole and includes the following steps:

[0122] C1: Adjust the angle adjustment oil cylinder group and the slewing mechanism A to complete the positioning of the opening angle of the water hole on the excavation face;

[0123] C2: Since the bolter miner stops construction when the onboard drilling rig is carrying out the construction of the water hole, the efficiency priority mode of mode 2 is selected for the onboard drilling rig to realize the rapid construction of the water hole;

[0124] C3: through mode 2 to control the primary feed cylinder A and the secondary feed cylinder A to realize the two-stage rod drilling of the power head;

Abstract

The invention discloses a rapid construction system and a method for anchor rod holes on the side wall of a tunneling working face and an advance borehole. The rapid construction system comprises an upper machine-mounted drilling machine, a lower machine-mounted drilling machine and a control system, the upper machine-mounted drilling machine is installed on a top platform of a tunneling and anchoring machine and used for construction of upper row anchor rod holes in two walls of a tunneling working face roadway and the advance borehole, the advance borehole comprises a tunneling working face water exploring and discharging hole, a region verification hole and a coal seam water injection hole, so that multi-purpose efficient utilization of the upper machine-mounted drilling machine is achieved, the lower machine-mounted drilling machine is mounted at the tail joint of a shuttle car and used for constructing lower row anchor rod holes in the two walls of the roadway, and the control system comprises a drill jamming control module, an automatic drilling module and a mode selection module and is used for automatic control over drilling construction of the drilling machine. According to the rapid construction system and the method for the anchor rod holes on the side wall of the tunneling working face and the advance borehole, comprehensive construction of tunneling, supporting, water exploring and discharging, region verification and water injection and dust reduction is achieved, the side wall anchor rod supporting efficiency is improved, the construction safety of a tunneling working face is guaranteed, dust on the tunneling working face is reduced, and the system and the method have great significance in efficient, safe and environment-friendly underground mining.

Description

technical field [0001] The invention belongs to the field of tunneling working face construction in underground tunnels of coal mines, and in particular relates to a rapid construction system and method for side rock bolt holes and advanced drilling holes in the driving face. Background technique [0002] In recent years, the degree of mechanization of fully-mechanized excavation in coal mines has been continuously improved. Bolter miners are used to cut roadways at one time and complete support at the same time. The excavation efficiency has been significantly improved, and the production intensity has been continuously increased. Threatening the health of miners; at the same time, the country's "Regulations on Water Prevention and Control in Coal Mine" clearly states the water prevention and control principle of "prediction and forecasting, detection in case of doubt, exploration before digging, treatment before mining", and the bolter does not have the ability to detect an...
