STUDY ON IN-SITU MEASUREMENT OF HYDRAULIC FEATURES OF BASE ROCKS

This paper describes an in situ measurement method of hydraulic features of rocks (including water pressure, water conductivity, discharge, high water conductivity fracture zone).Taking Taiyuan Dongshan Coal Mine as an example, in situ measurement method was used in determining the hydraulic features of base rocks stratum of carboniferous Taiyuan and Benxi groups. The obtained results are described in detail here. The research is of significance in coal mining above confined aquifer.
