采煤塌陷区地表动态演变对风蚀影响研究--以神府东胜煤田补连塔矿风沙区为例

The effects of ground surface change of the coal mining area on the wind eroson——A Case Study of Sandy Coal Mining Area of Bulianla Mine

文中以神府-东胜煤田补连塔矿风沙区为例,通过野外调查和观测,系统地分析了补连塔矿风沙区采煤塌陷后塌陷断裂面特征对地表动态演变及风沙蚀积量变化的影响关系。认为区域风沙蚀积量受塌陷断裂面的一系列特征指标影响明显,其构造特征所形成的塌陷断裂面落差(H)、偏移距离(L)、偏移角度(δ)与风沙蚀积量有直接或间接关系。因此,文中研究的主要目的就是搞清风沙区地表塌陷断裂面的一系列构造特征对区域风沙蚀积量的影响关系及地表动态演变规律,为有效控制采煤塌陷后地表风沙运动而采取科学的措施提供依据。

By the field survey and measurement to the coal minning subsided areas of the Buliante Mine, shendong Minning Area, the characters of the cracks , the geograhy changes and the wind erosion dynamics were analyzed. Results showed that the sand deposit was affected by the cracks obviously. The falls of the cracks, the excursion distances and the excursion angles showed the relations with the sand deposits. The conclusion of the study could contribute the scientific basis for the desertification control in the coal minning subsided area.
