摘要
以济宁花园煤矿1316工作面中央的B24点为例,运用时间序列、灰色系统理论及卡尔曼滤波3种模型分别对该点地表沉降值进行模拟及预报,并对3种数学模型的自适应性及模拟预报结果进行分析,探讨研究模型的模拟及预报的最大偏差表象是否可以反演矸石充填后特殊的地表沉降过程。对于完善充填开采引起的地表移动规律具有参考意义,对安全开采设计和地面建(构)筑物保护具有实用价值。
Is illustrated by the case of the Bu point which located in the center of 1316 working face of Huayuan coal mine, and the time series, the gray system theory and the Kalman filter model are used to simulate and predict the Bu point respectively, then the results are analyzed and the relationship between the surface subsidence inversion and the results is discussed. It is of significance for the surface movement law caused by the filling mining, which is valuable to the mining design and the buildings protection.
