Orientation underground exploitation method to develop for the Lang Vai of small scale antimol region, ​Tuyen Quang Province

Abstract

Vietnam's mineral resources are very rich yet dispersed; the majority of ore mining are on a modest scale. One such mine is the Lang Vai antimony mine in Tuyen Quang province. The mine contains around 55,000 tons of main ore reserves with a concentration of 0.07 4.56 percent. The ore body is spread in the form of beds, veins, and steep slopes. With these sorts of mines, the issue for mining engineers is balancing technological indications, mining safety, and cheap production costs. If mechanized mining technology is used, capital recovery is not possible; if manual technology is used, productivity and safety are low, and the payback period is long. The building solution is simple, based on an examination of the features of such a mine, which is naturally placed of the ore body, the mechanical and physical qualities of the surrounding rock, and so on, with the objective of the shortest ore production time. simple. The article offers a strategy to approach the ore body through a vertical well combined with a through-seam furnace, an ore storage mining system, the building of a pipeline to prepare for production in the ore body, and a road drill construction technique. Breaking rock with 36 mm glass using a blasting technique. Simultaneously, compute some fundamental efficiency requirements based on the chosen plan.
