Paste emulsion explosive for upward hole blasting and its preparation and use method
By cross-linking the oil phase and lubricant during the downhole charging process, a more viscous and less dense paste-like emulsion explosive is formed, solving the problems of explosive falling and poor blasting effect in upward hole blasting, and achieving a highly efficient and environmentally friendly blasting effect.

AI Technical Summary
In existing upward hole blasting methods, the charge is prone to falling off, resulting in waste of explosives and poor blasting effect. In addition, the foaming speed is slow, the catalyst acidity is insufficient, resulting in less foaming, insufficient initial viscosity, and insufficient expansion force. Especially in blast holes with water, there is a high chance of backflow of explosives.
During the downhole loading process, the acidic substances in the oil phase and lubricant cross-link and foaming reaction form a more viscous, less dense paste-like emulsion explosive, which is then mixed in the borehole using a static mixer to ensure the explosive adheres.
It achieves non-return-to-hole explosives, saves costs, reduces environmental pollution, improves blasting effect, optimizes viscosity and density, and reduces return rate.
