摘要
为了研究综放开采条件下的地表沉陷变形规律,郭庄煤矿建立了地表移动观测站,通过系统观测和研究,获得了特定地质采矿条件下地表岩移预计参数和角值参数,揭示了厚煤层综放开采条件下地表沉陷变形规律和特点,为矿井"三下"采煤和保护煤柱留设提供了可靠的依据。
In order to study the ground subsidence and deformation law of fully mechanized caving mining, in-situ observation station was made. Through system observation and research, The prediction parameters and angular parameters of the surface rock movement under the specific geological mining conditions were obtained revealing the law and characteristics of the surface subsidence deformation under thick coal seam fully mechanized caving mining conditions providing the scientific basis for ＂ under three＂ coal mining and the pillar design.
