Caving zone, water flowing fractured zone, the position feature of earth's surface curved bel；
Determine that underground water enters the water supplementing method of Goaf Area by roof caving band and water flowing fractured zone respectively；
S3：Note of one interval of water flowing fractured zone bottom as Regional is selected according to the position feature of fissure zone
Filled layer is starched, determines distribution occasion, trend and the tendency Distribution Characteristics of slip casting filled layer；
S4：The construction station of main vertical hole or main round is determined according to the position feature of Goaf Area and earth's surface curved bel,
According to the distribution occasion of slip casting filled layer, trend and the construction location and technical parameter that are inclined to Distribution Characteristics branched hole, branched hole
For horizontal pinniform oriented branch hole or fan-shaped branched hole；
S5：The drilling construction for leading vertical hole or main round is carried out, along main vertical hole or main round deflecting to slip casting filled layer, into
The drilling construction of row branched hole；
S6：Region slip casting is carried out by branched hole, slurries is diffused in slip casting filled layer by pressurization, it is each
A branched hole grout mixing mutually overlaps, and grout curing grouting behind shaft or drift lining filled layer forms closure surface layer, is subtracted by blocking surface layer
The increment of groundwater of few Atmospheric precipitation to abandoned mine Goaf Area in target area.
Further, in step S2, survey for the purpose of locating hydrogeological resources work includes geological drilling work and hydrogeophysical prospecting work.
Further, in step S2：
The position feature of Goaf Area includes：Distribution, area, depth and ponding situation；
