The rock salt resources in Dawenkou basin are abundant.The exploration and utilization of rock salt began in 1990s.According to the occurrence characteristics of rock salt layers and the characteristics of ore quality,rock salt in the basin have been explored by using drilling water solution method.In this pa-per,focusing on the mining method of rock salt,based on the investigation of present situation of rock salt mining,the origins and treatment methods of brine leakage and well blockage accidents in production have been analyzed.It is believed that strengthening the study of well group technical parameters can effectively improve resource utilization in rock salt drilling and water solution mining.In production,selecting high quality casing,improving cementing quality,strengthening production management and monitoring can ef-fectively prevent the occurrence of production accidents.
