Zusammenfassung: | The invention discloses a shallow-buried thin-foundation soft rock two-zone water control design method and a shallow-buried thin-foundation soft rock two-zone water control system, which are used for performing integral structural water inrush control on a rock stratum by utilizing the fracture sealing characteristic of a rock stratum two-zone structure after the shallow-buried thin-foundation soft rock is mined and optimizing and strengthening the structural characteristic through mining parameters and a process. The method mainly comprises the following steps: (1) investigating coal seam occurrence conditions and overlying strata conditions; (2) testing basic physical and mechanical parameters of the coal rock sample; (3) theoretical analysis is carried out to determine timely fracture conditions of bedrock; (4) designing working face mining parameters and mining roadway support parameters; and (5) optimizing mining parameters of the working face and supporting parameters of the mining roadway.
