摘　　要：在对彬长矿区自然环境、水土流失和煤炭开采等基本特征分析的基础上,认为采煤沉陷区是彬长矿区水土流失的关键区域。针对采煤沉陷区的区域特性,从"地下控制地表"的新视角,初选出7个显著影响采煤沉陷区水土流失的地下因子。以彬长矿区9个代表性煤矿为样本,运用灰色关联分析原理,甄选出采厚、采深为影响采煤沉陷区水土流失的地下关键因子。研究结果不仅深化和拓展了对采煤沉陷区水土流失基本特征和规律的认识,而且为采煤沉陷区水土流失的"地下与地表联动防控"提供了理论基础。On the basis of analyzing the basic characteristics of natural environment, soil and water loss, and coal mining in Binchang coal mines, mining subsidence area was identified as the key area of soil and water loss in this coal nfines. Aiming to the regional characteristics of mining subsidence area in Binehang coal mines, 7 underground mining influencing factors of soil and water loss were selected preliminarily, from a new view of underground controlling ground surface. Taking 9 typical coal mines as samples, mining height and mining depth were identified as key underground influencing factors, according to the principle of grey correlative analysis. The results could deepen and expand the understand for basic law and characteristics of soil and waler loss in mining subsidence area, furthermore, provide the theoretical basis for prevention and control of soil and water loss with a new path of underground combine surface.
