Abstract

The invention discloses a continuous striping bag-filling room and pillar type gob pillar stoping method. The method comprises the following steps of a, according to the pillar and goaf conditions, dividing a goaf into goaf stripes and pillar stripes containing a plurality of pillars; b, filling the goaf stripes; c, after the goaf stripes at both sides of each pillar stripe are filled, stoping the pillars in the pillar stripes; d, repeating the steps b and c, and stoping the next pillar stripe; e, after all pillars in the goaf are stoped, performing post-goaf treatment on the pillar stripes. The method has the advantages that the stoping technology is simple, and the production efficiency is high; the recovery rate of pillars is high; the safety is good, and the environment-friendly effect is realized; the cost is low; the method is suitable for room and pillar type pillar stoping and goaf treatment, especially slow-tilting ultrathin to thin ores.

Description

technical field [0001] The invention relates to the technical field of pillar mining in mines, in particular to a method for back-mining pillars in the empty space of a continuous strip bag-type filling room-and-pillar method. Background technique [0002] The room-and-pillar method is used for mine recovery. In order to support the roof of the mining space, regular ore pillars are left in the empty field. According to the survey, according to the mining technical conditions, when the room-and-pillar mining method is used for mining, the amount of ore pillars left generally reaches 5-30% of the ore amount of the ore block, and when the ore value is not high, some can reach 40-60%. . [0003] The characteristic of mineral resources is non-renewable. With the continuous exploitation of mineral resources, geological reserves are decreasing year by year. The loss rate is extremely high, and if it is not recycled, it will cause a serious waste of resources. In order to increas...
