基于灰色系统理论的矿山采后地面沉降预测

Prediction of Land Subsidence at Finished Underground Mining Based on the Grey System Theory

地下采矿导致地面沉陷的过程是一个复杂的系统性问题,准确预测因采矿导致的地面沉陷发展趋势,对于规避其危害具有重要的现实意义。根据灰色系统理论,以大量地面沉陷资料与实际原位监测资料为依据,构建起了平原地区采矿地面沉陷预测的灰色模型。以张楼煤矿为例,给出了灰色模型预测结果与实测结果的对比情况,证实了灰色模型预测的有效性。

Underground mining is one of the causes of land subsidence. The process of the land subsidence caused by underground mining is complicated and systematicness, Accurate prediction the land subsidence has important practical or immediate significance to avoid the harm of land subsidence. According to theory of grey system, a grey prediction model of land subsidence of underground mining in plains was established based on analysis of a vast amount of land subsidence material and many field monitoring data. Taking Zhanglou coal mine as an example, the results of compared the grey prediction model with the observation results has been given. The efficacy of the grey prediction model has been proved.
