Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] A drilling cementing slurry for uranium mining by in-situ leaching, comprising the following components:

[0018]

[0019]

[0020] Wherein, the percentage is the percentage of each admixture to the weight of the waste mud.

[0021] 1. Waste mud refers to the mud that is returned from the hole during the drilling construction process and is no longer used. It contains a certain proportion of bentonite, fine sand, water, etc., has good suspension and fluidity, and has a strong Toughness, plasticity and viscosity, its properties should be in the following ranges:

[0022] Density: 1.05~1.25g / cm 3 , Viscosity: 25 ~ 45s, sand content: 2.5 ~ 4% (volume ratio).

[0023] 2. Curing agent (slag): Slag is the waste residue produced in the iron-making process. After rapid water quenching at high temperature, a glassy granular hydraulic substance is...

Abstract

The invention belongs to the technical field of in-situ-leaching uranium mining, and particularly relates to an in-situ-leaching uranium-mining drilling well-cementing slurry. The invention aims to provide an in-situ-leaching uranium-mining drilling well-cementing slurry. Several particular reagents are added in waste mud generated in the drilling process, so that the prepared novel well-cementing slurry has the function of cement paste well cementing and satisfies the demands for in-situ-leaching uranium-mining drill well cementing. The in-situ-leaching uranium-mining drilling well-cementing slurry contains waste mud, a curing agent, an activator and an activation assistant in a weight ratio of 20:8:2:1. Compared with the normal cement well-cementing slurry well-cementing technique, the in-situ-leaching uranium-mining drilling well-cementing slurry can consume certain waste mud, lower the treatment cost of the waste mud and protect the mine environment when being used for well-cementing operation. The slurry has the advantages of small specific gravity and low pressure on the drilling well pipe, and protects the uranium-mining well pipe.

Description

technical field [0001] The invention belongs to the technical field of uranium mining by in-situ leaching, and in particular relates to a drilling cementing slurry for uranium in-situ leaching. Background technique [0002] In the production of in-situ leaching uranium mining, drilling is the only channel to expose the ore seam so that the leaching reagent can enter the ore seam and carry the ore-containing solution out of the surface. It is one of the most important facilities for in-situ leaching uranium mining. Well cementing is a key process of drilling construction, and its quality will affect the service life and working ability of the drilling. Since the 1980s, ordinary portland cement slurry has been used as the cementing slurry in the drilling and cementing of in-situ leaching uranium production. This kind of slurry has a higher density during cementing, which will generate greater pressure on the casing of the well; at the same time, during the cementing process, ...
