Measurement-while-drilling exploring tube device used for mining

Abstract

The invention provides a measurement-while-drilling exploring tube device used for mining. The exploring tube device comprises an end cap part, a supporting assembly, a damping body assembly, a base body assembly, an outer tube and a top pillar assembly; the end cap part is connected with the front end of the supporting assembly; the damping body assembly is installed at the position of a threaded hole in the supporting assembly along the center axis; one end of the outer tube is installed at the rear end of the supporting assembly; the top pillar assembly is installed at the other end of the outer tube; the base body assembly is installed on a connector on the core part at the rear end of the damping body assembly. In the measurement-while-drilling exploring tube device, a four-wing centering guide is added, it can be achieved that the damping and righting effects are enhanced, the coaxial precision of an exploring tube and a non-magnetic bin is improved, and the exploring tube device is not prone to erosion; a seven-core connector socket is added so that it can be achieved that the Baud rate of a sensor is adjusted in real time and the measurement-while-drilling data of the sensor is detected in real time; when a sliding ring connector plug of the top pillar assembly is connected with a sliding ring connector socket of the base body assembly, simple installation and disassembly and reliable connection can be achieved, the insulativity between a shell and an inner core of the exploring tube is improved, and the length of the exploring tube is shortened, so that the cost is reduced.

Description

technical field [0001] The invention belongs to the field of drilling measurement of underground gas drainage holes and geological exploration holes in coal mines, and in particular relates to a mine measuring-while-drilling probe device which is easy and reliable to install. Background technique [0002] The measurement-while-drilling probe is used in high-gas, high-dust, and high-humidity environments in underground coal mines, and can perform trajectory measurement while drilling drilling holes such as geological exploration holes and gas drainage holes. [0003] The probe tube based on measurement-while-drilling technology is used in conjunction with the matching measuring instruments of the directional drilling rig, which can measure the attitude information of the drilling tool in real time and guide the driller's engineer to achieve directional drilling. However, the probe tube structure is relatively complex and its reliability is poor. Contents of the invention ...
