Investigation of the Efficiency of the Application of Water Solution of Lexol Reagent for Preparation of Pulling

Abstract

A study of the effectiveness using the aqueous solution of the surfactant "Lexol" for dust suppression during mass explosions in quarries, on technological highways and use as an anti-freezing agent during transportation of bulk cargoes. The task was solved by conducting industrial studies to determine the effectiveness of reducing dust formation during mass explosions by pre-moistening the quarry blocks with the aqueous solution of surfactant "Lexol". Anti-dust reagent is an aqueous solution of glycerin component of plant origin, intended for fixing of erosion-hazardous surfaces of poly-mineral composition. Experimental explosions on the horizon of minus 360 m with the use of this reagent were carried out in the PJSC "Ingulets mining and processing integrated plant" quarry and industrial researches of dust binding on quarry roads with their watering by the aqueous solution of "Lexol". The optimal concentrations and amounts for application of the Lexol reagent to the surface of the dust and loose material during sprayingof the reagent and watering have been determined. Also, the effectiveness of using the aqueous solution of surfactant "Lexol" as an anti-freezing agent during transportation of bulk cargoes was investigated. It is determined that the reagent is economically efficient when used in the winter period of the year. In the research, the process of binding the dust particles by the surfactant "Lexol" remaining on the surface of the quarry block after drilling operations was confirmed, and which are actively involved in the overall process of forming a dust-gas cloud. At 5 % concentration of aqueous solution of the reagent "Lexol-5", the average effectiveness of dust suppression was 21 %. It is determined that the effective time of preserving the properties of the reagent on the road surface is about 10 days, and when repeated application of the aqueous solution of the surfactant "Lexol", the time of effective dust binding will increase
