针对香炉山钨矿大跨度多临空面复杂采空区治理难题,提出了围堰式袋装充填技术。该技术以采空区矿柱为拐点,采用充填袋围堰封堵充填处理空区,矿山在Ⅰ盘区E2~E6采场北端约3万m~3空区现场试验结果表明,该技术解决了高大采空区挡墙架设难题,实现了采空区分区充填治理,围堰充填成本为135.7元/m3、空区充填成本为118元/m3,达到了安全经济可靠处理空区的目的,同时为矿柱回采奠定了基础。 Aiming at the problem of complex gob area management in large-span multi-channeled mines in Xiangluo-Shan tungsten mine, a cofferdam bagging technology was proposed. The technology takes mined-out pillars as the inflection point, and adopts filling cofferdam to fill and fill the empty area. The field test results of about 30,000 m ~ 3 empty areas at the northern end of the E2 ~ E6 stopes in the area Ⅰ of the mine show that the technology solves the problem The problem of erection of retaining wall in high gob area was realized. The filling of gob partition was achieved. The filling cost of cofferdam was 135.7 yuan / m3 and the filling cost of empty area was 118 yuan / m3, achieving the goal of safe and economical processing of empty area. At the same time laid the foundation for mining pillars.
