Cable disengaging device, cable conveying assembly and timed recycling method

Abstract

The invention discloses a cable disengaging device, a cable conveying assembly and a timed recycling method. The cable disengaging device is provided with a cylindrical body, and the open end of the body is provided with a limiting end cover; a positioning supporting piece is arranged in the body in the axial direction, a soluble connecting body is installed on the positioning supporting piece, and a variable-diameter connecting body is arranged on the periphery of the soluble connecting body in a clamping connection mode. A cable connecting body axially penetrates through the limiting end cover, and the variable-diameter connecting body is hinged to the cable connecting body. The technical problem that a resistivity monitoring cable is hydraulically conveyed through a non-inner flat drill rod in a coal mine underground bottom plate directional long hole is solved, and the construction convenience of working face bottom plate water-abundance audio electrical method perspective exploration is improved; the recovery problem after the construction of the resistivity monitoring cable is completed is solved, the construction economy of the base plate hole water-abundance audio electrical method perspective exploration is improved, and the technology is more beneficial to popularization and application.

Description

technical field [0001] The invention relates to the fields of underground coal mine drilling engineering and geophysical prospecting engineering, in particular to a cable release device, a cable conveying component and a timing recovery method. Background technique [0002] After the coal mine working face is formed and during the mining process, the precise detection of the water-rich hidden danger in the floor is an important measure to eliminate the water hazard. At present, water-rich audio-frequency electrical perspective exploration has been gradually popularized and applied in coal mines through the directional long drilling holes drilled in the floor of the working face and lowering the resistivity monitoring cable. Compared with the one-time inspection in the traditional roadway, it can not only The one-time inspection before the mining of the working face can also be used for continuous monitoring during the mining process of the working face, which has become an e...

AI Technical Summary

Problems solved by technology

[0003] The invention aims at the technical problem that the non-inner flat drill rod cannot be used to transport the cable in the directional long drilling hole of the underground floor of the coal mine and the cable cannot be recovered after the resistivity monitoring in the hole, and provides a cable release device, a cable conveying assembly and Timing recovery method to meet the construction convenience and economic requirements of accurate detection of water-rich hidden dangers in the floor
