Abstract

The invention discloses a blade for cutting a uranium mining casing and reaming an ore-bearing and water-bearing stratum, and relates to the field of drilling construction of an in-situ leaching process. According to the blade for cutting the uranium mining casing and reaming the ore-bearing and water-bearing stratum, a cutting edge of the blade is composed of alloy sheets and composite sheets; the alloy sheets are located at the head and the tail of the cutting edge of the blade; the composite sheets are located in the middle of the cutting edge of the blade; and the blade is matched with a cutting tool. According to the scheme, the blade is suitable for casing cutting and ore-bearing and water-bearing stratum reaming, abrasion is smaller, the service life is longer, and the cutting efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of drilling construction in ground leaching technology, and in particular relates to a blade for cutting uranium mining casing and expanding holes in ore-bearing aquifers. Background technique [0002] Drilling by in-situ leaching technology is the only channel for metal mining in in-situ leaching sandstone-type uranium mines. This channel is composed of casing, filter, and sand settling pipe from top to bottom. It is a working channel for the hydraulic connection between the surface pipeline and the aquifer, and is called a production well. In the construction process of in-situ leaching drilling, it is usually necessary to use a blade to cut the uranium mining casing, or use a blade to ream the ore-bearing aquifer. The two targets are different, and the blade needs to be replaced during use, which is extremely Greatly affects the cutting efficiency. [0003] Therefore, there is an urgent need for a blade that is s...
