摘　　要：针对现代煤炭开采中地下水和地表生态保护问题,选择神东矿区补连塔矿的超大综采工作面,研究了风积沙区采动覆岩破坏规律和减损途径。研究表明:在相同开采环境下,工作面宽度和推进速度,是控制覆岩破坏程度的关键。首次采用相对损伤系数比较发现,增加工作面和推进速度,可降低采动覆岩结构相对损伤程度。这对减小采动裂隙带高度,促进采后地表生态修复都有重要作用。In view of protection problems on ground water ＆ earth＇s surface ecology in modern coal mining, this paper makes a research on the failure law and depletion approaches of mining overburden rock in drift-sand area taking example by the mining conditions of oversized fully mechanized coal mining face in Lianbuta coal mine of Shendong diggings. And the research shows that： face width and flitting speed are the keys for overburden failure controlling under same exploitation conditions. Comparative damage factor is lowered for the first time, working face adding and flitting speed lowered comparative damage degree of mining overburden rock structure. It plays significant role in mining fissure zone height decreasing and ecological remediation after mining.
