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