But when we mine commensuration groundwater, the falling velocity water level and range of the deep hydrous stratum are bigger than the shallow hydrous stratum. And the quantity of subsidence is not obvious different. 2. Analyzing the relation between the stratum of groundwater and land subsidence, with the depth of aquifer bed increased, the proportion that the released water because of compressibility of strata possessed become bigger, and it cause land subsidence more serious. 3. The physical and mechanical properties and the consolidation state of stratum do not become better with the depth increased.
