Comprehensive Detection Of Hydrogeological Conditions And Design Of Water Prevention In Panel 101 Of The Yuwang Coal Mine No.1 In Yunnan Province

In this paper,taking the panel 101 in Yunnan Yuwang coal mine No.1 as research object,the engineering geological and hydrogeological conditions of the study area were analyzed,including topographic and geomorphic features,stratigraphic lithology,geological structure,hydrological and meteorological conditions and site stability.Isotope testing and hydro-chemical analysis as well as ground geophysical prospecting,underground geophysical prospecting,underground drilling and draining test were used to determine the source and pathway of water inrush from the boreholes of the roadway in panel 101.Meanwhile,the water recharge conditions of the coal mine was determined and a comprehensive analysis for panel 101 was carried out.The results provide a reasonable basis for mine water inrush prevention and serve as a technical support for the building of mine safety and the design of effective mine water inrush prevention measures.Based on the survey data and the comprehensive detection results of various projects,the water prevention and control plane of water-proof coal pillars setting in the roadway of panel 101 was designed.Meanwhile,the water prevention and control measures for the roadway of panel 101 and for the panel 101 were proposed.
