摘　　要：为有效解决建筑物下积压煤柱的安全绿色开采问题,结合矿区环境实际,提出了控制地表变形的地表黄土综采置换煤炭技术。本文对当地黄土的物理及力学特性进行了测试分析,并根据开采引起的地表变形预计结果,确定了合理的"等价采厚",提出相应的预处理措施。In order to effectively resolve safe green mining problem of baeklogings coal pillar under building, combines the actual environment of the mining area, puts forward the surface loess replacement coal with full mechanized mining technology for control the surface deformation. This text tests and analyses physical and mechanical properties of local loess, and accordingg to expected result of surface deformation caused by mining determines reasonable＂ equivalent mining thickness＂ ,also puts forward corresponding pretreatment measures.
