Analysis on Mine Shaft Abnormal Water and Prevention Technologies in Deep and Thick Overburden
LI Wan-feng
Abstract：For the deep overburden of Huainan coal mine freezing shaft water phenomenon ,this paper analyzes the mechanism and prevention measures to this water. First of all ,on the detailed analysis of engineering geological and hydrological conditions ,freezing method sinking construction technology and based on force mechanism of borehole wall ,points out that the deep topsoil freezing shaft water reason mainly ,revealed the deep mechanism of topsoil freezing shaft water ;Then ,puts forward the corresponding prevention measures ,and points out that should strengthen the wall temperature and stress monitoring of the process ,prevention and treatment of informatization.
Keywords：deep and thick overburdenmine shaftfreezing methodmechanism of the waterprevention and control measures
