Problems solved by technology

Invention patent 202010504519.9 provides an emulsion explosive that can quickly adjust hardness and viscosity and its preparation method. This patent can solve the problem that the existing bulk emulsion explosive is soft during production and use, and can also solve the problem of mixing emulsion explosive on site. The problem of drug return when charging the upward hole
However, the distribution method of the latex matrix involved in the method (2) and the above-mentioned invention patents is to produce the latex matrix at the ground station in the mining area for distribution. This method has the problem of high investment costs; and the ground station in the mining area produces Latex matrix usually has a high viscosity, although it can solve the problem of drug return, it will lead to the dilemma of difficult drug delivery

Abstract

The invention discloses a remote distribution underground mining emulsion matrix, which comprises a water phase component and an oil phase component, and the oil phase component comprises mineral oil,paraffin oil and an emulsifier. is the invention also discloses an emulsion explosive comprising an emulsion matrix, a catalyst, and a sensitizer. The invention further discloses a preparation methodof the remote distribution underground mining emulsion matrix. The preparation method comprises the following steps: preparing the water phase; preparing the oil phase; adjusting the flow rate of a pump according to the ratio of the water phase to the oil phase, adjusting the rotating speed of an emulsifier according to the viscosity of the target emulsion matrix, pumping the water phase and theoil phase to the emulsifier, and emulsifying to form the emulsion matrix. The emulsion matrix disclosed by the invention has good bumping resistance, can be remotely distributed to mines within 1500 kilometers for users to use, and can be sensitized at normal temperature to form the emulsion explosive. The explosive can be sensitized after being installed in an upward blast hole, the explosive return phenomenon is avoided, the blasting cost can be greatly reduced, the blasting effect is effectively improved, and dangerous factors existing in blasting construction and other construction processes are greatly reduced.

Description

Technical field [0001] The invention belongs to the field of civilian explosive production, and relates to the remote distribution of latex matrix for underground mines, in particular to emulsion explosives, and more particularly to a preparation method for remotely distributed underground mine latex matrix. Background technique [0002] Underground mining occupies an important position in the mining of metal mines. With the continuous development of technology in the civil explosive industry, the application proportion of on-site mixed emulsion explosives and charging vehicles in underground mines has gradually increased. At present, in the process of underground mine mining, the mode of deploying a latex matrix production ground station in a mine is usually used to distribute the latex matrix. Although this latex matrix distribution method does not require high performance of the latex matrix, it has a high investment cost. The problem. In order to reduce production costs and ...
