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.
