厚冲积层薄基岩下采煤地表移动变形规律

Surface movement influenced by mining below thick alluvia and thin bedrocks

通过对淮北矿业 (集团 )有限责任公司童亭煤矿地表移动观测资料的研究分析 ,揭示了厚冲积层薄基岩下采煤地表移动变形的一般规律和特点 ,为类似地质采矿条件下的“三下”

The general rule and characteristics of surface movement influenced by mining below thick alluvia and thin bedrocks are found after analyzing the observing data gained in Tongting colliery, Huaibei Coal Mining Group Co. Ltd. This offers some technological reference on how to mine coal similar to the conditions.
