Description

Technical Field

[0001] The invention belongs to the technical field of underground tunnel drilling in coal mines, and specifically discloses a built-in advanced exploration drilling device of an integrated digging and anchoring machine, an integrated digging and anchoring machine and an advanced exploration drilling method. Background Art

[0002] "Explore when in doubt, explore before digging" is the basic safety requirement for tunnel excavation in underground coal mines. During construction, excavation, support, and exploration of hidden disaster factors are carried out in an alternating manner, resulting in limited space for advance detection and tight construction time. The drilling method is highly intuitive and has a wide range of applications. It plays an irreplaceable role in coal mine exploration technology. The geological conditions of foreign coal mines are simple, and directional long drilling is generally used for overall exploration of the mining work area. The advance detection technology, including drilling and geophysical exploration, has been developing in the direction of stability and reliability, fast detection, and continuous improvement in positioning and observation accuracy.

[0003] With the increasing concentration of coal production in China, fast and accurate advance detection technology and equipment can provide effective geological safety guarantee and is one of the necessary technologies for intelligent and rapid tunneling. However, in terms of advance drilling at the head of tunneling, my country's coal mines currently generally dig ear tunnels on the side of the tunnel and use drilling equipment for drilling construction, rather than directly conducting advance exploration construction at the head of tunneling. The main reason is the lack of efficient and fast integrated drilling and anchoring drilling technology and equipment.

[0004] Domestic coal mines have an increasingly urgent demand for adding water detection modules to all-in-one digging and anchoring machines. By combining the technology of all-in-one digging and anchoring machines with the technology of advanced water detection in drilling, a new type of all-in-one digging, anchoring and detection machine has been invented. This can reduce equipment relocation, reduce the labor intensity of workers, increase the excavation footage, and reduce the number of underground workers. It is of great significance to resolve the contradictions between the four major processes of "detection, excavation, support, and anchoring".

[0005] The traditional approach to adding a forward probe drill to the integrated mining and anchoring machine is to place the forward probe drill directly on the cutting arm. However, the problem with this arrangement method is that when the cutting arm is performing cutting operations, the onboard wet dust removal blower interferes with the forward probe drill. Due to space limitations, the onboard wet dust removal function and the forward probe function cannot be integrated on the same integrated mining and anchoring machine at the same time, which limits the adaptability of the integrated mining and anchoring machine. Summary of the invention

[0006] The present invention is aimed at the technical problem that the prior art directly arranges the forward exploration drill rig on the cutting arm. Due to space limitation, during the cutting operation of the cutting arm, the airborne wet dust removal blower interferes with the forward exploration drill rig, and the airborne wet dust removal function and the forward exploration function cannot be integrated simultaneously on the same drilling and anchoring machine. The present invention provides a built-in forward exploration drilling device for a drilling and anchoring machine, a drilling and anchoring machine and a forward exploration drilling method, thereby improving the adaptability of the drilling and anchoring machine.
