AI Technical Summary

Technical Problem

Existing drill pipes are prone to deformation and damage when encountering rocks, leading to damage to drilling equipment and increased exploration costs. Furthermore, large-scale mechanical construction can damage vegetation.

Method used

A novel tunneling method is adopted, which uses components such as a grip rod, drill rod and anti-drop ring inside the drill barrel to switch between conventional tunneling and rock breaking mode by reciprocating lifting and rotation of the grip rod. After breaking the rock, the soil and rock are smoothly collected, avoiding direct collision between the drill barrel and the rock.

Benefits of technology

It effectively avoids drill barrel deformation, improves drilling efficiency and hole quality, reduces equipment wear and damage to vegetation during construction, and is suitable for drilling needs in complex strata.

Abstract

The application relates to the technical field of geological exploration, and discloses a novel ion type rare earth production exploration rock jamming digging method, which comprises the following steps: S1, drilling holes according to exploration points, and assembling a complete set of digging devices at the exploration points; S2, reciprocatingly lifting a handle of the digging device by hand, drilling downwards by using impact, and collecting rock soil in a ring-shaped gap between a drill rod and an inner wall of a drill cylinder to realize sampling; S3, when drilling encounters rock jamming and isolated rock and drilling progress is blocked, temporarily pausing the pressing operation; S4, adjusting the circumferential position of the handle to change a power transmission route, reciprocatingly lifting the handle to apply impact to break the rock jamming at the bottom of the hole. The rock breaking stress carrier is transferred from the drill cylinder body to the built-in drill rod, so that the problem of deformation, cracking and damage of the drill cylinder caused by directly hard collision with the rock jamming is avoided.
