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.

依据： ①一般情况下，随深度增加，地层的压缩性会渐下；但是开采同量的地下水，其水位下降的速率及幅度深部含水组比浅部含水组要大的多，两者引起的沉降量不会有明显的差别；②从地下水开采资源组成与地面沉降关系分析，含水层深度越深，其中的压密释水量所占的比例也越大，造成的地面沉降也越严重；③地层的物理力学性质及固结状态，随深度的增加，也不完全是越来越好。
