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。
Taking the wind-sand area of the Shenlian-Dongsheng coalfield in Beiliantai as an example, through field investigation and observation, the authors systematically analyzed the dynamic evolution of the surface and the amount of wind-sand erosion in the sand area of the Beiliantai mining area after collapse The impact of change. It is considered that the sand aeolian volume in the area is significantly affected by a series of characteristic indexes of the collapsed fracture surface. The structural characteristics of the collapsed fracture surface such as drop (H), offset distance (L), offset angle (δ) Have a direct or indirect relationship. Therefore, the main purpose of this study is to find out the relationship between the series of tectonic features of the surface subsidence surface and the dynamic evolution of the ground surface, and to take scientific measures to effectively control the surface wind and sand movement after coal mining subsidence Measures provide the basis.
