| 摘 要： | 为保证煤层安全开采,对淮南煤田张集煤矿西三采区的疑似岩溶陷落柱进行探查。布置了地面钻探工程,研究了钻孔钻进过程中遇陷落柱时所出现的识别特征,同时分析了井温变化,并通过盐化扩散测井测定了涌漏水层位。钻探及试验测试结果表明该陷落柱为中心轴南倾、上小下大的非完全陷落柱,其范围大于三维地震勘探资料解释范围。

| Abstract: | In order to insure safe production of coal mine,in exploration on suspected karst collapse column of west No.3 panel in Zhangji Coal Mine of Huainan coalfield was made.This paper decorated the surface drilling projects,identification features revealed when boreholes driving meet collapse column were also studied,well temperature changes were researched when the drilling drilled.Leaking seams were determined by evapo-salinization diffusion logging.Researches indicated that the exist of the collapse column wa... |
