摘要
煤层采空形成的冒落带、裂隙带和沉降变形情况的查明对灾害防治及土地利用是非常重要的,在勘察钻孔中进行声波扫描成像测井能提供清晰直观的图像资料,给工程地质的评价分析提供了可靠的依据。
It is very important for disaster pre vention and curing and application o f land to find out the caving zones,crack zones formed after coal exploitation and s ubsidence conditions.The clear and intuitionistic images can be made by sound wave scaning imaging logging in exploration hole,and providing the reliable basis fo r engineering geological appraisal and analysis.
