某煤矿巷道上方建筑物开裂原因分析

Analysis on Causes of Building Cracking above a Coal Mine Roadway

采矿工业生产和矿区建设的发展过程中引起的地表建筑设施的损坏给矿产企业带来巨大的经济赔偿负担,但并非所有位于巷道或采空区上方的建筑物开裂都是由矿产开采引起的。具体分析了陕西省某煤矿巷道上方建筑物开裂产生的原因,认为造成建筑物开裂的主要原因是地基湿陷变形及地下水位下降,而非巷道的开挖。不仅为合理制定建筑物病害处置方案奠定了基础,同时也减少了不必要的支出。可为同类型的巷道或采空区上方建筑物开裂原因分析提供借鉴与参考。

The building cracking is caused by development of mining production and mining area construction burden on mineral enterprises, but not all building cracking is caused by mining production which aboves roadway or gob. The cause of building cracking above a coal mine roadway in Shaanxi province has been analyzed in this paper, points out the real reason is collapse deformation of foundation and groundwater drawdown of the site, but not the excavation of roadway. The conclusion of this paper is beneficial for the work of restoring, also can reduce unnecessary expenses of the coal mine, and this paper could provide reference for the similar projects.
