Abstract

The invention discloses an electronic control telescopic drilling tool for borehole hydraulic mining. The electronic control telescopic drilling tool for the borehole hydraulic mining is composed of a high pressure water conveying system, a power transmission system, a hydraulic giant telescopic system and a deslagging channel. A hydraulic giant of the electronic control telescopic drilling tool can stretch out for a designed distance in the radial direction, the range of the borehole hydraulic mining is enlarged greatly, and production efficiency is improved. The electronic control telescopic drilling tool for the borehole hydraulic mining has the advantages that the rotating angle and speed of a stepping motor can be controlled accurately through a computer, the opening angle of the hydraulic giant can be controlled precisely, and the stretching and retracting actions of the hydraulic giant are stable through the transmission mode of a ball screw.

Description

technical field [0001] The invention relates to a drilling tool, in particular to an electronically controlled telescopic drilling tool for hydraulic mining of boreholes. Background technique [0002] With the rapid development of my country's economy, the mining industry is facing the depletion of surface and shallow rich minerals, while deep underground minerals, shallow uneven small mines, lean ore, lake and seabed minerals, and minerals with complex hydrological and geological conditions It has the problem of great mining difficulty. The use of traditional methods to mine deep minerals and shallow uneven small mines and lean mines will inevitably bring about high costs. All countries are looking for a low-cost mining method for this reason, and drilling hydraulic mining is exactly a new mining method produced under this historical background. [0003] The drilling hydraulic mining method is to break the ore body with high-pressure water jet in the drill hole passing thr...
