薄煤层开采条件下地面建筑物移动变形观测

摘要

兖州矿区杨村煤矿火药库下采煤是该矿首次进行的建筑物下采煤试验研究项目.本文主要介绍该矿在薄煤层开采条件下地面建筑物所受到的采动损坏程度以及用对比法分析地表移动与房屋变形的关系,同时也分析研究了该矿具体地质采矿条件下地表岩层移动的一般规律.%It is the first time that the Yang village mine has excavated coal under powder storeroom. The damage level of buildings disturbed by mining in the thin coal seam has been introduced. The authors use antithesis to analyze the relationship between the moving of the surface and the damage of buildings,and discuss the normal principles of the moving of the surface ground under the specific geological and coal mining situation.
