基于DEM的龙口煤矿塌陷区水域淹没分析

SUBMERGE ANALYSIS OF LONGKOU MINING SUBSIDENCE AREA BASED ON DEM

以龙口塌陷区为研究对象,在DEM数据基础上进行采煤塌陷区的确定.在采煤塌陷区范围内,该研究采用无源淹没分析法,给出了给定水位条件下的塌陷区水域淹没分析方法,计算出各年份采煤塌陷区的水域淹没范围.通过遥感影像进行计算结果的验证,表明采煤塌陷区水域淹没范围预计结果较准确.因此采用平面模拟的方法进行采煤塌陷区淹没范围的计算是可行的,能够对塌陷区积水区域的治理和合理利用提供依据.

Taking the Longkou subsidence area as the research area, this paper deteimines the mining subsidence area based on DEM data firstly. In the mining subsidence area, the paper calculates the submerged area by the non- source flood analysis, and proposes the analysis of submerged area under the condition of water - level. Prepared by the remote images, the results of submerged range in mining subsidence area are coincident with practical verification. The research suggests that it is feasible to simulation of flooding range in the mining subsidence area by plane simulation. It can provide the basis for controlling and making use of coal mining subsidence area.
