Abstract: In order to effectively protect and develop the underground water resources in the ecological frail zone of West China Area,according to the modern coal mining affected to the overburden strata structure and the underground water deposit environment,taking the super large fully mechanized coal mining face in Shendon g Mining Area as an example,a modern high precision geophysical detection and analysis method was applied to establish a multi attribute data volume with high precis ion 4D seismic multi attribute data as a core.The paper represented the overburden strata variation process of the seam mining under the conditions before the mining operation,in the middle period of the mining face,at the mining terminal period and the strata stabilized period.The paper pointed out that overburden strata above the s eam mining would have opened multi strata seepage structure and layered self recovered tendency,which could provide the theoretical basis to the underground water「 esources protection under the modern coal mining technology in West China Area.
