Study on Coal Mine Hydro-geological Classification Standards in Shendong Mining Area
WANG Zhenrong
Abstract：According to the main types of water damage and hydro-geological characteristics in Shendong Mining Area,the mine hydro-geological classification basis in Prevention and Control of Coal Mine Water Regulations is studied.The hydro-geological classification standard in northwest China and the method for mining water inflow data with distributed drainage system are emphasized.Through investigating and collecting the annual output,water inflow and drainage system type,increasing drainage coefficient of ton coal of national multiple mines,the hydro-geological classification standard for Shendong Mining Area is determined finally,and the method of using comprehensive weighted average coefficient method to define the hydro-geological type is proposed.
