摘　　要：在松散层或基岩厚度变化较大时,采用地表移动观测站综合角量参数代替松散层与基岩的角量参数确定的开采影响范围往往与实际差别较大。文中对唐山矿岳各庄观测站实测资料进行分析,采用沉陷学角量参数与采深的几何关系求得了该区松散层与基岩的边界角和移动角。对松散层与基岩变化较大的矿区地表移动观测站角量参数的求取具有一定参考价值。When the change of the soil layer or bedrock thickness is larger,the differences are often larger than actual if you use surface movement observation station integrated angle parameters instead of the angle parameters of loose layer and the bedrock to determine the extent of mining.In this paper,the author analyzes the measured data of Yue Ge Zhuang observation stations in Tangshan Mine,and obtains boundary angle and angle of critical deformation using the geometry relationship between subsidence angle geometry and mining depth.It has a certain reference value for getting surface movement observation station angle parameters in loose layer and the bedrock where the change is larger.
