【摘要】 通过北宿煤矿村庄下双对拉工作面开采的地表移动观测,探讨了地表移动变形与房屋变形及其裂缝发育宽度之间的关系,获得了预测房屋裂缝宽度的典型曲线.该曲线可以对房屋裂缝的发育规律作出较为精确的定量预测,对房屋将出现的最大破坏程度有充分的估计.最后,给出了动态下沉系数和水平移动系数的修正公式.

【Abstract】 Based on in situ measurement of ground movement for mining under village in Beisu Coal Mine using two double unit faces, the relationship between the deformation and fissure width of buildings and the movement of ground is investigated. And a typical curve of predicting the fissure width of buildings is gained. The quantitative prediction of the fissure width induced by coal mining can be made more accurately. Finally, corrective formulas for dynamic subsidence factor and horizontal movement coefficient are given.
