Embodiment 1

[0040] see Figure 1-Figure 5 , an integrated bolter digging machine integrated with a water jet system, specifically applied to coal excavation, includes an integrated bolter digging machine 1 and a water jet system arranged on the integrated bolter digging machine 1, and the integrated bolter digging machine 1 includes For the cutting drum 9 for construction on the face, the water jet system includes a water jet drilling device and a face cutting device both arranged on the integrated bolter 1, and the face cutting device is used for The water jet drilling device is used for drilling or drilling and slitting operations for performing slitting operations on the face of the face.

[0041] The face cutting device includes a water jet nozzle 13 and a nozzle multi-degree-of-freedom boom 14, the water jet nozzle 13 is arranged on the nozzle multi-degree-of-freedom boom 14, and the nozzle multi-degree-of-freedom boom 14 is arranged on On the integrated bolter 1. The palm face sli...

Embodiment 2

[0065] see Image 6 The difference between this embodiment and Embodiment 1 is that the water jet drilling device is different. The water jet drilling device in this embodiment includes a water jet drilling rod 16 and a drilling machine, and the water jet drilling rod 16 is detachably arranged on the On the drilling rig, a water jet drill pipe storage is provided on one side of the drilling rig, and water jet drilling rods of different specifications are arranged in the water jet drilling rod storage. Among them, the drilling rig comes with the bolter. By replacing the original drill pipe with a water jet drill pipe, drilling or drilling and cutting operations can also be realized. The end of the water jet drill pipe is connected to the high-pressure hose through a rotary joint. to achieve normal work. According to the existing structure of the bolter miner, the drilling rig is arranged on the cutting boom 8 through the sliding platform and the rotary platform. The advantage ...

Abstract

The invention provides a digging and anchoring all-in-one machine integrated with a water jet system. The digging and anchoring all-in-one machine comprises a digging and anchoring all-in-one machine body and the water jet system arranged on the digging and anchoring all-in-one machine body; the digging and anchoring all-in-one machine body comprises a cutting roller used for constructing a tunnel face; and the water jet system comprises a water jet drilling device and a tunnel face joint cutting device which are both arranged on the digging and anchoring integrated machine body, wherein the tunnel face joint cutting device is used for conducting joint cutting operation on the tunnel face, and the water jet drilling device is used for drilling or drilling joint cutting operation. The water jet system is integrated to the tunneling and anchoring all-in-one machine body for tunneling and anchoring operation, and the tunneling and supporting operation effects of the tunneling and anchoring all-in-one machine body can be effectively improved in the aspects of tunnel face tunneling, roadway supporting and the like; and roadway space deformation and gas outburst are effectively reduced, multi-way supporting is achieved, and roadway stability is improved. The invention further provides a construction method using the digging and anchoring all-in-one machine integrated with the water jet system.

Description

technical field [0001] The invention relates to the technical field of a bolt-digging integrated machine, in particular to an integrated water-jet system-integrated anchor-digging machine and a construction method. Background technique [0002] Coal is one of the main energy sources in my country, and it accounts for a large proportion of the total primary energy production and consumption in the country. Compared with the tunneling of coal mine underground roadway by fully mechanized excavator or blasting, the one-time roadway anchoring technology of bolter not only improves the safety of the production environment, but also greatly improves the operation efficiency. However, when a hard gangue layer is encountered, the integrated machine of the bolter has problems such as low excavation efficiency and serious equipment wear and tear. [0003] In addition, during roadway support, the integrated bolter miner faces problems such as complex anchorage rock structure, high stre...
