Problems solved by technology

When the coal and rock mass in the anchorage area is relatively broken or the stress is high, after the anchor cable drilling construction is completed and the drill pipe is withdrawn, the borehole will be deformed or even collapsed, resulting in difficulty in feeding the anchoring agent and anchor cable or the waste hole
Therefore, there are many anchor cable construction procedures, long time, and easy hole collapse etc. are the main shortcomings of the prior art

Abstract

The invention discloses a water jet technology based anchor rope self-drilling and rapid anchoring construction method. The method comprises the following steps that an angle adjustable type drillingmechanism is adjusted so that a hollow anchor rope can face a preset drilling direction; a water jet generation device is connected with the rear end of the hollow anchor rope; the water jet generation device and the angle adjustable type drilling mechanism are started to do drilling work; after drilling work is completed, a rigid pipe is coaxially connected to the rear end of the hollow anchor rope, and the rigid pipe is mounted on the angle adjustable type drilling mechanism; a discharging opening of an anchoring agent feeding device is connected with the rear end of the rigid pipe; and theanchoring agent feeding device and the angle adjustable type drilling mechanism are started to do anchoring work on the hollow anchor rope in a drilled hole. In the drilling process, no heat is generated, no spark is generated, no dust is generated, safety is achieved, and noise is low; and meanwhile, the procedures of drilling rod drilling and rod retreating are omitted, operation is simple, andautomatic control can be achieved easily. An anchoring agent is blown in from a hole in the hollow anchor rope, and the problem that cartridge anchoring agents are hard to feed does not exist.

Description

technical field [0001] The invention belongs to the technical field of mining engineering, and in particular relates to an anchor cable self-drilling and rapid anchoring construction method based on water jet technology. Background technique [0002] Anchor cable support is a commonly used support technology in mining engineering, geotechnical engineering, and underground engineering. The length of the anchor cable is long and the anchoring range is large, and it has become the most important support method for coal mine roadways in my country when used in conjunction with bolt support. [0003] The length of anchor cables ranges from 3 to 4 meters to more than ten meters. The length of anchor cables commonly used in coal mines is about 6 to 10 meters. ~10 drill pipes, complete the drilling construction, and then withdraw the drill pipes one by one; use the anchor cable to send the anchoring agent into the drilling hole, the anchoring length of the anchor cable is generally...
