近水平煤层开采地表沉陷预测系统研究

Study on surface subsidence forecasting system of nearly flat coal seam mining

针对煤矿近水平煤层开采沉陷特点,采用随机介质理论进行预测研究,综合考虑矿区开采地质及采矿技术影响因素,合理取舍预测参数值,结合开采实例,编制了近水平煤层开采地表沉陷研究预测系统。系统实现了沉陷研究的一系列功能模块,采用本系统能够准确直观预测近水平煤层开采沉陷区的发展变化情况,预测结果实用,利于地表移动变形的整体分析研究。

Against the features of near level seam coal mining subsidence,the random medium theory is applied to make a predict research,considering the factors of mining geology and the impact of mining technology,a reasonable trade-off parameter predicted value,combined with real exploitation example,the near level coal mining subsidence forecast system is coded,this system realizes a series of functional modules,using this system can accurately and intuitively predict the development and the situation of near level coal mining subsidence in recent,and the predict results are practical,it is beneficial to make an analysis about the overall surface deformation.
