In this paper, the theories, techniques, methodologies, and results of monitoring primary fractures connecting to the injection well in Anpeng Alkali Mine are presented, which combines micro-seismic monitoring with leveling survey techniques. By these theories, techniques and methodologies, the production well was located within the fractured band connecting to the injection well at a depth of over 1 000 meters, which makes it possible for continuous water injection and alkali solution production in Anpeng Alkali Mine.
