摘　　要：程潮铁矿淹井后采准井巷大面积坍塌 ,给生产造成严重影响。本文通过对矿岩所含粘土矿物成分类型及含量、崩解和软化特性的试验研究 ,分析水对采场巷道围岩变形的影响程度和途径 ,查清了井巷大面积坍塌的主要原因。After the inundation of shaft in Chengchao Iron Mine,large area collapse of development openings caused serious influence on production.Based on test and research on the types and contents of clay minerals contained in ore rock and their crumbling and softening properties,this paper analyzed the degree and ways of stope drift wallrock deformation affected by water,found out the major cause for the large area collapse of openings.This offers important reference value for the cause analysis and comprehensive control of opening collapse in similar skarns mines.
