Abstract

The invention discloses an open-pit mine water-rich deep hole isolation slurry material and a preparation method thereof. The raw materials include fly ash: clay: water: foaming agent: accelerator: early strength agent: thickener =50:50:37‑38:3:2.5‑3:2:2‑3. Mix and stir fly ash, clay, quick-setting agent, early strength agent, and thickener for 3-5 minutes in a dry state; add foaming agent to water and stir fully and rapidly for 3-5 minutes; add the resulting mixture to the mixture, Stir for 1‑2min while incorporating as many air bubbles as possible, and let stand for 20min. The density of the material is slightly higher than that of water, which is close to the density of the sensitized emulsion explosive and is incompatible with it. It has a certain anti-dispersion ability under water, and has a low viscosity and good fluidity. It can effectively solve the isolation problem of water-rich deep-hole explosives, save the amount of emulsion explosives, and is easy to operate, and can flexibly adjust the amount of isolation materials according to the site conditions, thereby achieving different isolation distances. It can be injected through the pipeline, and finally realize the quantitative isolation of blasting explosives in the water hole and discharge the accumulated water in the hole.

Description

technical field [0001] The invention relates to an open-pit blasting technology, in particular to an open-pit mine water-rich deep hole isolation slurry material and a preparation method thereof. Background technique [0002] In the open-pit deep hole blasting, due to the water content in the rich water deep hole blasting, it is impossible to separate, water spray and dust after blasting often occur, and the unit consumption of explosives is high. In order to reduce the technical and economic waste caused by excessive charge and improve the blasting effect, it is sometimes necessary to carry out segmented isolation charge for deep holes. [0003] The existing technology of segmented isolation charging in rich water and deep holes mostly uses mechanical isolation devices, which are costly, complicated to operate, low in efficiency, and the site conditions are complex and changeable. The isolation effect is poor, and it is difficult to be widely used in rich water deep hole b...
