Progressive backfill mining technology with split and two wings

: With the large-scale development of mining industry, soil and water loss, environmental pollution other geological disasters ac-companied by coal are continually increasing. Therefore, while promoting mine production relying on scientific technological progress, measures to control reduce resulting cannot be ignored. In this paper, taking Xiezhuang as an example, we have combined its actual conditions solve problems caused massive accumulation surface gangue in mine. Moreover, improve efficient recovery resources ensure safety deep mining, rock burst damage underground body, a re-search forward filling technology with split-wing is put forward. This paper mainly discusses related technologies laws method split-wing, system, process, mining.
