底板下三带探测技术实例应用

Floor Down Three Zone Detection Technology Example Application

为正确评价下组煤开采受水威胁程度,为底板防治水工作提供依据,以新阳煤业有限公司开采9-10-11号煤层工作面为例,通过"钻孔双端封堵测漏装置"探测底板破坏深度方法,获得采动底板破坏深度的实际数据。重点介绍该方法的探测原理和观测方法,为类似情况提供技术经验借鉴。

In order to evaluate lower coal seam threaten by water and provide basis for floor water prevention and control, No.9-10-11 working face of Xinyang Mining Company was taken as example, drilling double side sealing and side leak detection device was used to detect seam floor s fracture depth, actual data of mining floor damage depth was obtained. The detection principle and observation methods were introduced, which provided technical experience and reference for similar condition.
