     The down - hole seismograph can monitor lots of weak earthquake waves that can not be recorded by ground seismographs. The down - hole strata deformation observation can avoid natural and human disturbances on the surface of the earth, which allows observational data to reflect truly strata changes, and greatly improves the source location accuracy. In this work, combined with practical engineering, the design of earthquake monitoring wells, drilling and cementing technology were analyzed. According to the special requirements of earthquake monitoring wells, the technology of preventing bore- hole deviation and the new craft of layered grouting cement were adopted during the drilling, making the perpendicularity of the earthquake monitoring wells and cementing quality both be excellent, which provides a basic guarantee to obtain accurate earthquake monitoring data.
