Abstract
In order to find out the law of water gushing in Xiwan open-pit coal mine,prevent water accidents in the process of mining and stripping,and avoid the inundation of mining personnel and equipment,it is necessary to analyze and evaluate the source of water gushing and the amount of water gushing in the mining pit.By analyzing the geological exploration,hydrological supplementary exploration data,testing and monitoring data,combined with the types and characteristics of groundwater and the factors of water filling,Darcy's law section method and hydrogeological analogy method are used to pre-dict the amount of water gushing in coal mining pits,analyze and summarize the risk of water gushing in each aquifer,pro-pose corresponding treatment plans,design important parameters such as the capacity and layout of the reservoir,and verify the capacity of coal mine pumping and drainage equipment,so as to meet the demand of water gushing in coal mining pits and prevent the adverse impact of water gushing on production safety.关键词
