| 摘 要： | 针对原万利矿区厚风积砂层、薄基岩、浅埋深的煤层赋存条件,为探明采动覆岩破坏规律,利用经验公式对垮落带和裂隙带高度进行预测,采用钻孔冲洗液法进行覆岩破坏观测,从而确定了上覆岩层"三带"的高度,为确保在第四系含水砂层下安全开采提供了科学依据.

| Abstract: | Based on the existence conditions of thick sand strata,thin bed-rocks,and shallow buried of previous Wanli Mine,the study,in order to explore the laws of overburden failure,predicts the height of caving zones and fracture zones through experience formula.Drilling flush liquid method is used to measure the overburden failure and the heights of Three Zones of overburden strata are determined.The research provides the scientific proof for safety mining in the quaternary watered sand layers. |

| Keywords: | caving zone fracture zone shallow buried flush liquid overburden movement |
