采煤沉陷盆地的积水承载力研究

Research on the Hydrops Capacity of Coal Mining Subsidence Basins

根据开采沉陷预计方法和测量计算理论,推导出任意工作面开采沉陷积水承载力的计算方法,并结合实际案例进行了论证,研究表明:采煤沉陷盆地积水承载力的大小不仅取决于开采程度,同时与沉陷盆地边缘最低点高程、区域地形起伏粗糙度的大小有着密切关系;基于现有的GIS数据处理软件和计算机自动化数据处理系统,采用的积水承载力计算方法,可对任意地形、任意工作面采动沉陷预计结果进行直接计算,可为采动沉陷环境规划和综合治理提供可靠的理论支撑和科学方法.

According to the existing mining subsidence prediction methods and research theories,a method to calculate the mining subsidence hydrops capacity of the working face is deduced and demonstrated by some examples.The results show that the factors determining the hydrops capacity consist of the degree of the mining activities,the elevation values of the lowest point in the subsidence basin marginal and the topography roughness of the study area.Based on the current GIS and computer automated data processing system,the method proposed in this paper can directly calculate the subsidence predicted results in any topography and any mining face.The authors hope that the results of this research can provide a reliable scientific basis for mining subsidence environmental planning and integrated management.
